创建服务端的restful controller

@RestController
@Controller
public class IndexController {


    @PostMapping("/index")
    public IndexResDto index(@RequestBody IndexReqDto indexReqDto) {
        System.out.println("indexReqDto = "+indexReqDto);
        return new IndexResDto(1,"gaoxinfu","man",18);
    }
}

注意 springboot与springcloud版本的一个对照 参考

application.properties配置

spring.application.name=springboot-sample-openfeign-client
server.port=8085

调用服务端的client接口编码

@FeignClient(name = "demo",url = "http://localhost:8086")
public interface ServerFeignClient {

    @GetMapping("/index")
    IndexResDto index(@RequestBody IndexReqDto indexReqDto);
}

客户端restful controller编码

@RestController
@Controller
public class DemoController {

    @Resource
    private ServerFeignClient serverFeignClient;

    @GetMapping("/client/index")
    public IndexResDto index(@RequestParam int id) {
        return serverFeignClient.index(new IndexReqDto(id));
    }
}

客户端调用验证 源码
