Java spring boot - 返回一个json响应

Question

我想为新的 Java Spring Boot 应用程序创建自定义 json 响应。目前我只想创建一个虚拟 json 对象——开始控制输出 json 响应的结构。

当我这样做时，它想为 .puts 创建强制转换前缀——我曾经使用 Mongodb——BasicDBObject——但现在我这里没有 mongo。

 DBObject obj = new BasicDBObject();
 obj.put( "foo", "bar" );

我该怎么做？

@RequestMapping(value = "/login", method = RequestMethod.GET)
@CrossOrigin(origins = {"*"})
public ResponseEntity<?> login(
        @RequestParam(value="email", required=false, defaultValue="email") String email,
        @RequestParam(value="password", required=false, defaultValue="password") String password, 
        HttpServletRequest request
        ) throws  Exception {

                Object response = new Object();
                    response.put("information", "test");
                    response.put("id", 3);
                    response.put("name", "course1");

                return new ResponseEntity<>(response, HttpStatus.OK);
        }

**@ResetController**   // add this
public class YourClass{

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    @CrossOrigin(origins = {"*"})
    public ResponseEntity<?> login(){
        Object response = new Object();
                    response.put("information", "test");
                    response.put("id", 3);
                    response.put("name", "course1");

        return new ResponseEntity<>(response, HttpStatus.OK);
     }
}
