微服务调用-feign | 程序员灯塔

消费者:

1 controller层自动注入自定义的feign接口:

@Resource
FeignService feignService;

2 配置文件配置feign调用超时时间,默认一秒,根据需要适当增加:

hystrix:
  command:
    default:
      execution:
        timeout:
          enabled: false
ribbon:
  ReadTimeout: 120000

3 创建feign接口:

//配置文件中生产者的微服务名
@FeignClient(name="${spring.application.meName}")
public interface FeignService {

  //  feign的接口，value是指定消费者调提供者的接口名,提供者对外提供什么接口，这里就定义什么接口
    @PostMapping(value = "/me/industry/addUrl")
    public String addUrl(@RequestBody List<JSONObject> list, @RequestParam(value="secuCode") String secuCode, @RequestParam(value="user") String user, @RequestParam(value="type") int type,@RequestParam(value="endDateType") String endDateType);
    @PostMapping(value = "/me/industry/addUrl2")
    public String addUrl2();
    @PostMapping(value = "/me/industry/addTag")
    List<HashMap> addTag(@RequestParam(value = "user",required = false) String user,@RequestBody List<HashMap> data,  @RequestParam(value = "supplier",required = false) String supplier, @RequestParam(value = "starCompany",required = false)String starCompany);

　　注意list类型的参数需要用@RequestBody注解,string类型参数可以用@requestParam

生产者:

编写接口:

@PostMapping("/addTag")
    public List<HashMap>  addTag(@RequestParam(value = "user",required = false) String user,@RequestBody(required = false) List<HashMap> data,@RequestParam(value = "supplier",required = false) String key,@RequestParam(value = "starCompany",required = false) String type){
        return data;
    }
