@RequestMapping(value = "/rest/article", method = POST, produces = "application/json") public WebResponse> saveArticle(@RequestBody Article article) { article.setUserId(1L); articleService.saveArticle(article); Map ret = new HashMap<>(); ret.put("id", article.getId()); WebResponse> re...
public Result<User> getUserDetail(@RequestParam Map<String,Object> map) { System.out.println(map); System.out.println(map.get("name")); return Result.success(null); } } 2.以 body json 格式传参,RequestBody 注解接收参数 @RestController @RequestMapping("/user") @Slf4j public class UserContr...
@GetMapping("/helloworld4")publicString helloworld4(@RequestParam Map<String, Object>params) {return"name:" + params.get("name") + "<br>age:" + params.get("age"); } } (2)下面是一个简单的测试样例: 4,接收一个数组 (1)假设请求地址是如下这种,有多个同名参数: http://localhost:8080/hell...

SpringBoot接收map类型的参数 本文共215字,预计阅读时间1分钟 如果某个controller的某个接口的参数特别多,也可以使用map的方式来接收参数,接收之后使用get方法获取即可。 1)get请求方式,定义map接收方式 @RequestParam(required = false) Map map 2)post请求方式,定义map接收方式...
Map map=new HashMap(); map.put("result",res); return map; } 为了看得更明白,我放一下service代码: public String studentLogin(String userName,String pswd){ String isUser="false"; Student s=properties.findByUsername(userName); if(s.getPswd().equals(pswd)) ...
(1)、JSON参数接收 例如:添加用户的接口, 前端PostMan 请求信息如下: 后端接收代码1: @PostMapping(value = "/user/map")public ResultVO createUser(@RequestBody Map<String,Object> user){String name=user.get("name").toString();return RV.success(user);} ...
