整合SSM

环境要求

环境:

  • IDEA
  • MySQL 5.7.19
  • Tomcat 9
  • Maven 3.6

要求:

  • 需要熟练掌握MySQL数据库,Spring,JavaWeb及MyBatis知识,简单的前端知识;

一、底层

数据库环境

创建一个存放书籍数据的数据库

`ssmbuild`

USE `ssmbuild`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

基本环境搭建

1、新建一Maven项目!ssmbuild , 添加web的支持

2、导入相关的pom依赖!

        </dependency>

    </dependencies>

3、Maven资源过滤设置

<build>
   <resources>
       <resource>
           <directory>src/main/java</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
       <resource>
           <directory>src/main/resources</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
   </resources>
</build>

4、建立基本结构和配置框架!

  • com.kk.pojo
  • com.kk.dao
  • com.kk.service
  • com.kk.controller
  • mybatis-config.xml

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">


</beans>

Mybatis层编写

1、数据库配置文件 database.properties

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/mybatis?useSSL=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
username=root
password=123456

2、IDEA关联数据库文件 spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置整合mybatis -->
    <!-- 1.关联数据库文件 -->
    <context:property-placeholder location="classpath:database.properties"/>

    <!-- 2.数据库连接池 -->
    <!--数据库连接池
       dbcp 半自动化操作 不能自动连接
       c3p0 自动化操作(自动的加载配置文件 并且设置到对象里面)
   -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!-- 3.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4.配置扫描Dao接口包,动态实现Dao接口注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.kk.dao"/>
    </bean>

</beans>

3、编写MyBatis的核心配置文件 mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <typeAliases>
        <package name="com.kk.pojo"/>
    </typeAliases>

    <mappers>
        <mapper resource="com/kk/dao/BookMapper.xml"/>
    </mappers>
</configuration>

4、编写数据库对应的实体类 com.kk.pojo.Books

使用lombok插件!

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.12</version>
</dependency>
package com.kk.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

5、编写Dao层的 Mapper接口!

package com.kk.dao;

import com.kk.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {
    //增加一个Book
    int addBook(Books book);

    //根据id删除一个Book
    int deleteBookById(@Param("bookID") int id);

    //更新Book
    int updateBook(Books books);

    //根据id查询,返回一个Book
    Books queryBookById(@Param("bookID") int id);

    //查询全部Book,返回list集合
    List<Books> queryAllBook();

    //搜索书籍模块
    Books queryBookByName(@Param("bookName") String bookName);
}

6、编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包;

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.kk.dao.BookMapper">

    <!--增加一个Book-->
    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books(bookName,bookCounts,detail)
        values (#{bookName}, #{bookCounts}, #{detail})
    </insert>

    <!--根据id删除一个Book-->
    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID=#{bookID}
    </delete>

    <!--更新Book-->
    <update id="updateBook" parameterType="Books">
        update ssmbuild.books
        set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
        where bookID = #{bookID}
    </update>

    <!--根据id查询,返回一个Book-->
    <select id="queryBookById" resultType="Books">
        select * from ssmbuild.books
        where bookID = #{bookID}
    </select>

    <!--查询全部Book-->
    <select id="queryAllBook" resultType="Books">
        select * from ssmbuild.books
    </select>

<!--    搜索书籍模块-->
    <select id="queryBookByName" resultType="Books">
        select * from ssmbuild.books where bookName=#{bookName}
    </select>

</mapper>

7、编写Service层的接口和实现类

接口:

package com.kk.service;

import com.kk.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;
//BookService:底下需要去实现,调用dao层
public interface BookService {
    //增加一个Book
    int addBook(Books book);
    //根据id删除一个Book
    int deleteBookById(int id);
    //更新Book
    int updateBook(Books books);
    //根据id查询,返回一个Book
    Books queryBookById(int id);
    //查询全部Book,返回list集合
    List<Books> queryAllBook();
    //搜索书籍模块
    Books queryBookByName(String bookName);
}

实现类:BookServiceImp

package com.kk.service;

import com.kk.dao.BookMapper;
import com.kk.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class BookServiceImp implements BookService{
    //调用dao层的操作,设置一个set接口,方便Spring管理
    @Autowired
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books book) {
        return bookMapper.addBook(book);
    }

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    @Override
    public int updateBook(Books books) {
        System.out.println("BookServiceImp:updateBook=>"+books);
        return bookMapper.updateBook(books);
    }

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    @Override
    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    @Override
    public Books queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

OK,到此,底层需求操作编写完毕!

二、Spring层

1、配置Spring整合MyBatis,这里数据源使用c3p0连接池;

2、编写Spring整合Mybatis的相关的配置文件;spring-dao.xml

3、Spring整合service层

spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置整合mybatis -->
    <!-- 1.关联数据库文件 -->
    <context:property-placeholder location="classpath:database.properties"/>

    <!-- 2.数据库连接池 -->
    <!--数据库连接池
       dbcp 半自动化操作 不能自动连接
       c3p0 自动化操作(自动的加载配置文件 并且设置到对象里面)
   -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!-- 3.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4.配置扫描Dao接口包,动态实现Dao接口注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.kk.dao"/>
    </bean>

</beans>

4、Spring整合service层

spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"

    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">

<!--    <import resource="classpath:spring-dao.xml"/>-->

    <!--1. 扫描service相关的包-->
    <context:component-scan base-package="com.kk.service"/>


<!--   2.将我们所有业务类,注入到Spring 可以通过配置或者注解实现-->
    <bean id="BookServiceImp" class="com.kk.service.BookServiceImp">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>


    <!-- 3.声明式事务配置 -->
    <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--        注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>


    <!--       4.aop事务支持-->
    <!--    结合AOP实现事务的植入-->
    <!--    配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="TransactionManager">
        <!--            给哪些方法配置事务-->
        <!--            配置事务的传播特性,new-->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>

    <!--    配置事务切入-->

    <aop:config>
        <aop:pointcut id="txPointCut" expression="execution(* com.kk.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>



</beans>

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>


</beans>

三、SpringMVC层

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!--    Session-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

spring-mvc.xml

    </bean>

</beans>

3、Spring配置整合文件,applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>



</beans>

配置文件,暂时结束!Controller 和 视图层编写

1、BookController 类编写 , 方法一:查询全部书籍

@Controller
@RequestMapping("/book")
public class BookController {
    //controller层调service层

    @Autowired
    @Qualifier("BookServiceImp")
    private BookService bookService;

    //查询全部的书籍  并且返回到一个书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }
}

2、编写首页 index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
    <style type="text/css">
      a {
        text-decoration: none;
        color: black;
        font-size: 18px;
      }
      h3 {
        width: 180px;
        height: 38px;
        margin: 100px auto;
        text-align: center;
        line-height: 38px;
        background: deepskyblue;
        border-radius: 4px;
      }
    </style>
  </head>
  <body>
  <h3><a href="${pageContext.request.contextPath}/book/allBook">进入书籍页面</a></h3>
  </body>
</html>

3、书籍列表页面 allbook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>查询书籍展示页面</title>
    <%--BookStrap美化界面--%>
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

</head>
<body>
    <div class="container">
        <div class="row clearfix">
            <div class="col-md-12 column">
                <div class="page-header">
                    <h1>
                        <small>书籍列表 ———— 显示所有书籍</small>
                    </h1>
                </div>
            </div>

            <div class="row">
                <div class="col-md-4 column">
<%--                    toAddbook--%>
                    <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增书籍</a>
                </div>
            </div>
        </div>

        <div class="row clearfix">
            <div class="col-md-12 column">
                <table class="table table-hover table-striped">
                    <thead>
                        <tr>
                            <th>书籍编号</th>
                            <th>书籍名称</th>
                            <th>书籍数量</th>
                            <th>书籍详情</th>
                            <th>操作</th>
                        </tr>
                    </thead>

<%--                    书籍从数据库中查询出来,从这个list中遍历出来,foreach--%>
                    <tbody>
                        <c:forEach var="book" items="${list}">
                            <tr>
                                <td>${book.bookID}</td>
                                <td>${book.bookName}</td>
                                <td>${book.bookCounts}</td>
                                <td>${book.detail}</td>
                                <td>

                                    <a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.bookID}">修改</a>
                                    &nbsp; | &nbsp;
                                    <a href="${pageContext.request.contextPath}/book/deleteBook/${book.bookID}">删除</a>
                                </td>
                            </tr>
                        </c:forEach>
                    </tbody>
                </table>
            </div>
        </div>
    </div>

</body>
</html>

4、BookController 类编写 , 方法二:添加书籍

//    跳转到增加书籍页面
    @RequestMapping("/toAddBook")
        public String toAddPage(){
        return "addBook";
        }
//        添加书籍的请求
@RequestMapping("/addBook")
    public String addBook(Books books){
        System.out.println("addBook=>"+books);
        bookService.addBook(books);
        return "redirect:/book/allBook";// 重定向到我们的  @RequestMapping("/allBook")请求;
    }

5、添加书籍页面:addBook.jsp


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
    <%--BookStrap美化界面--%>
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

</head>
<body>
<div class="container">
    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>新增书籍</small>
                </h1>
            </div>
        </div>
    </div>
</div>

<form action="${pageContext.request.contextPath}/book/addBook" method="post" class="text-center">
    <div class="form-group">
        书籍名称:<input type="text" name="bookName" required>
    </div>
    <div class="form-group">
        书籍数量:<input type="text" name="bookCounts" required>
    </div>
    <div class="form-group">
        书籍详情:<input type="text" name="detail" required>
    </div>
    <input type="submit" value="添加">
</form>



</body>
</html>

6、BookController 类编写 , 方法三:修改书籍

//    跳转到修改书籍页面
    @RequestMapping("/toUpdatePage")
    public String toUpdatePage(Model model,int id){
        Books books = bookService.queryBookById(id);
        System.out.println(books);
        model.addAttribute("QBooks",books);
        return "updateBook";
    }

//    修改书籍请求
@RequestMapping("/updateBook")
    public String updateBook(Model model,Books books){
        System.out.println("updateBook=>"+books);
    int i = bookService.updateBook(books);//真正修改到业务层进行修改
    if (i>0){
        System.out.println("添加books成功"+books);
    }
        return  "redirect:/book/allBook";
    }

7、修改书籍页面 updateBook.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>修改书籍信息</title>
    <%--BookStrap美化界面--%>
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

</head>
<body>
<div class="container">
    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>修改书籍信息</small>
                </h1>
            </div>
        </div>
    </div>

    <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
<%--        出现的问题,我们提交了修改SQL请求,但是修改失败,初次考虑 是事务问题 配置完毕事务 依旧失败!--%>
<%--        查询一些SQL语句能否执行成功,SQL执行失败  修改未完成--%>
<%--         前端传递隐藏域--%>
            <input type="hidden" name="bookID" value="${QBooks.bookID}">
        <div class="form-group">
            <label>书籍名称:</label>
            <input type="text" name="bookName" class="form-control" value="${QBooks.bookName}"/>
        </div>
        <div class="form-group">
            <label>书籍数量:</label>
            <input type="text" name="bookCounts" class="form-control" value="${QBooks.bookCounts}"/>
        </div>
        <div class="form-group">

</body>
</html>

8、BookController 类编写 , 方法四:删除书籍

//删除书籍
@RequestMapping("/deleteBook/{bookId}")
public String deleteBook(@PathVariable("bookId") int id){
    bookService.deleteBookById(id);
    return "redirect:/book/allBook";
}

8、BookController 类编写 , 方法五:查询书籍

//查询书籍
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){  //从前端接收名字
    Books books = bookService.queryBookByName(queryBookName);
    System.err.println("queryBook=>"+books);
    List<Books> list=new ArrayList<Books>();
    list.add(books); //查询出来只显示这一本

    if (books==null){
        list=bookService.queryAllBook();
        model.addAttribute("error","未查到");

    }

    model.addAttribute("list",list);
    return "allBook";

}

9、 方法四:删除书籍、方法五:查询书籍相关jsp,合并在allBook.jsp中

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

                </div>
            </div>

            <div class="row">
                <div class="col-md-4 column">
