FeignClient 接口请求 模板

feign的使用在spring cloud中的使用 

 导入依赖1.4.4.RELEASE

      <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-feign</artifactId>
       </dependency>

  1,首先在类或实现类里调FeignService的请求接口

@Service
@Transactional(readOnly = true, rollbackFor = Exception.class)
public class feignClient {
    @Autowired
    private FeignSevice feignSevice;

    public List<StudentVO> getstudentAllk(List<StudentVO> student,String Id) {
        JSONObject json = FeignSevice.feignClient (Id,student);
    }
}

  2,通过FeignService接口请求,服务名为“zx-student”的服务;如果有信息需要请求头通过@RequestHeader放入;

      @RequestMappering塞入:请求的方法路径,请求方式;@RequestBody请求方法入参

@Component
@FeignClient(value = "zx-student") //服务名
public interface FeignSevice{
     // 请求路径,请求方式  @RequestHeader请求头
    @RequestMapping(value = "/sw/ass/getStudentAll",method = RequestMethod.POST)
    JSONObject feignClient(@RequestHeader("tenant") String tenant,@RequestBody List<StudentVO> student);

}

  3,最后需要在启动类里加入两个注解

   @EnableFeignClients
   @EnableTransactionManagement
