使用Fign进行客户端远程调用和SpringFormEncoder的使用

1、引入依赖

java"><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

2、启动类加上注解

java">@EnableFeignClients
@SpringBootApplication
public class FeignTestApplication {public static void main(String[] args) {SpringApplication.run(FeignTestApplication .class, args);}}

3、新增接口暴露的接口

java">@FeignClient(value = "feign2",path="/feignService",configuration=MultipartSupportConfig.class)
public interface FeignTestService {@PostMapping(value = "/getUser", consumes = APPILICATION_JSON_UTF8_VALUE)List<UserInfor> getUserList(@Requesbody  UserInvo inVo);//用于修改spring默认的encoder配置@Configurationclass MultipartSupportConfig{@Beanpublic SpringFormEncoder feignFormEncoder(ObjectFactory<HttpMessageConverts> convert ){return new SpringFormEncoder(convert );}
}

先配置生成了SpringFormEncoder的bean对象，然后在@FeignClient注解中配置configuration值来修改默认Encoder。
这里使用的并不是spring标准的encoder配置，

4、使用@AutoWired进行注入，调用

java">@AutoWired
private FeignTestService feignTestService;@PostMapping("/getUsers")
@ApiOperation("查询用户列表")
public List<UserInfor> getUserList(UserInVo inVo){return feignTestService.getUserList(inVo);
}
