请求多参数的URL
假设请求的URL包含多个参数,如:http://localhost:8086/user1?id=1&username=nihao
1.1、Feign接口
@FeignClient(name = "spring-ribbon-eureka-client2") public interface UserFeignClient { @RequestMapping(value = "/{id}", method = RequestMethod.GET) public User findById(@PathVariable("id") Long id) throws Exception; /**get方式,多参数请求方式一*/ @RequestMapping(value = "/find", method = RequestMethod.GET) public User find1(@RequestParam("id") Long id, @RequestParam("username") String username) throws Exception; /**get方式,多参数请求方式二*/ @RequestMapping(value = "/find", method = RequestMethod.GET) public User find2(@RequestParam Map<String, Object> map) throws Exception; /**post方式,多参数请求*/ @RequestMapping(value = "/find", method = RequestMethod.POST) public User find3(@RequestBody User user) throws Exception; }
1.2、使用
package com.example.demo.controller; import com.example.demo.feign.UserFeignClient; import com.example.demo.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import java.util.HashMap; import java.util.Map; /** * 用户controller * * @Author: 我爱大金子 * @Description: 用户controller * @Date: Create in 11:07 2017/7/10 */ @RestController public class UserController { @Autowired private UserFeignClient userFeignClient; @GetMapping("/user/{id}") public User findById(@PathVariable Long id) throws Exception { if (null == id) { return null; } return this.userFeignClient.findById(id); } @GetMapping("/user1") public User find1(User user) throws Exception { System.out.println("get方式,多参数请求方式一 : " + user); if (null == user || null == user.getId()) { return null; } return this.userFeignClient.find1(user.getId(), user.getUsername()); } @GetMapping("/user2") public User find2(User user) throws Exception { System.out.println("get方式,多参数请求方式二 : " + user); if (null == user || null == user.getId()) { return null; } Map<String, Object> map = new HashMap<String, Object>(); map.put("id", user.getId()); return this.userFeignClient.find2(map); } @PostMapping("/user3") public User find3(User user) throws Exception { System.out.println("POST方式,多参数请求方式 : " + user); if (null == user || null == user.getId()) { return null; } return this.userFeignClient.find3(user); } }
