前端控制器交给的页面控制的

 

package cn.itsource.controller;

接收参数用的实体类

package cn.itsource.query;

import cn.itsource.util.BaseQuery;

 

public class ArticleQuery extends BaseQuery{

private Boolean enable;
@Override

}
public void setEnable(Boolean enable) {

分页实现都会继承该类接收gridmanger提交的参数

}
public void setPageSize(Integer pageSize) {

mapper.update(article);
System.out.println(article);
return article;
}
}

 

 

 

 

文章管理实现类会调用的mapper

 

 

 

package cn.itsource.mapper;

import java.util.List;

import cn.itsource.domain.Article;
import cn.itsource.query.IArticleQuery;

public interface Articlemapper {
List<Article> findAll(IArticleQuery query);
Integer findTotalCount(IArticleQuery query);
void delete(Long id);
List<Article> findArticleByCode(String constant);
void add(Article article);
void update(Article article);
Article findOne(Long id);
void del(Long id);
Article findById(Long id);
Article findByURL(String url);
}

 

 

 

 

 

文章管理mapper映射文件

 

 

<?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”>
<!–
这个Mapper的主要功能就是写sql
mapper:根
namespace:命令空间 (用来确定唯一)以前这个是可以不加的,现在必需加
namespace的值:接口的完全限定名
–>
<mapper namespace=”cn.itsource.mapper.Articlemapper”>

 

<!– void update(Article article);修改 –>
<update id=”update” parameterType=”Article”>
update t_article set url=#{url},clickCount=#{clickCount},title=#{title},typeId=#{typeId},enable=#{enable},content=#{content},createDate=#{createDate} where id=#{id}
</update>

<!– void add(Article article);添加 –>
<insert id=”add” parameterType=”Article”>
insert into t_article (title,typeId,enable,url,content,createDate)
values (#{title},#{typeId},#{enable},#{url},#{content},#{createDate})
</insert>

 

<!– void delete(Long id);删除 –>
<delete id=”delete”>
delete from t_article where id=#{id}
</delete>

<select id=”findTotalCount” resultType=”int” parameterType=”ArticleQuery”>
select count(id) from t_article
<include refid=”query”></include>
</select>

<!– List<Article> findAll(ArticleQuery query); –>
<select id=”findAll” resultType=”Article” parameterType=”ArticleQuery”>
select * from t_article
<include refid=”query”></include><!– 先高级查询然后在分页 –>
limit #{begin},#{pageSize}
</select>
<sql id=”query”>
<where>
<if test=”typeId != null”>
and typeId = #{typeId}
</if>
<if test=”enable != null”>
and enable = #{enable}
</if>
<!– test里面的写法是ognl表达式,trim()是ognl语法:去掉两端的空白 –>
<if test=”title != null and ” != title.trim()”>
<!– concat是mysql的函数:用于拼接字符串的 –>
and title like concat(‘%’,trim(#{title}),’%’)
</if>
</where>
</sql>
<!– Article findByURL(String url); 根据url查找Article–>
<select id=”findByURL” resultType=”article”>
select * from t_Article where url=#{url}
</select>

<!– List<Article> findArticleByCode(String constant); –>
<select id=”findArticleByCode” resultType=”article”>
SELECT * FROM t_article t1
INNER JOIN t_article_type t2 on t1.typeId=t2.id
WHERE t1.`enable`=1 and t2.code=#{constant}
ORDER BY t1.createDate desc
LIMIT 0,8
</select>
<!–Article findById(Long id);–>
<select id=”findById” parameterType=”long” resultType=”article”>
select * from t_article where id = #{id}
</select>
<!– Article findOne(Long id); –>
<select id=”findOne” parameterType=”long” resultType=”article”>
select * from t_article where id = #{id}
</select>
</mapper>
