使用Feign构造多参数请求——POST请求包含多个参数

一 修改电影微服务控制器

package com.itmuch.cloud.study.user.controller;

import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

import com.google.common.collect.Maps;
import com.itmuch.cloud.study.user.entity.User;
import com.itmuch.cloud.study.user.feign.UserFeignClient;

@RestController
public class MovieController {
  @Autowired
  private UserFeignClient userFeignClient;

  @GetMapping("/user/{id}")
  public User findById(@PathVariable Long id) {
    return this.userFeignClient.findById(id);
  }

  /**
   * 测试URL:http://localhost:8010/user/post?id=1&username=张三
   * @param user user
   * @return 用户信息
   */
  @GetMapping("/user/post")
  public User post(User user) {
    return this.userFeignClient.post(user);
  }
}

二 修改UserFeignClient接口

package com.itmuch.cloud.study.user.feign;

import com.itmuch.cloud.study.user.entity.User;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.*;

import java.util.Map;

@FeignClient(name = "microservice-provider-user")
public interface UserFeignClient {
  @RequestMapping(value = "/{id}", method = RequestMethod.GET)
  public User findById(@PathVariable("id") Long id);

  @RequestMapping(value = "/post", method = RequestMethod.POST)
  public User post(@RequestBody User user);
}

三 修改用户微服务控制器

package com.itmuch.cloud.study.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import com.itmuch.cloud.study.entity.User;
import com.itmuch.cloud.study.repository.UserRepository;

@RestController
public class UserController {
  @Autowired
  private UserRepository userRepository;

  @GetMapping("/{id}")
  public User findById(@PathVariable Long id) {
    User findOne = this.userRepository.findOne(id);
    return findOne;
  }


  @PostMapping("/post")
  public User post(@RequestBody User user) {
    return user;
  }
}

四 测试

1 启动Eureka

2 启动用户微服务

3 启动电影微服务

4 访问 http:// localhost :8010/user/post?id=1 &username =张三
