Spring：响应REST ful API调用

Question

我正在尝试在y应用程序中实现REST APIendpoint。

@Controller
 public class HerokuController {

    @RequestMapping(value = "/heroku/resources/", method = RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE)
    public  ResponseEntity<JSONObject> provision(@RequestBody JSONObject body){
        System.out.println("called! \n");
        JSONObject response = new JSONObject();
        response.put("id", 555);
        response.put("message", "Provision successful!");
          return new ResponseEntity<JSONObject>(response,HttpStatus.OK);        
    }

因此，我编写了包含映射为（Heroku/ResSources）的方法的类。但是当我试图调用它时，我得到一个404错误，因为没有找到/WEB-INF/heroku/resources.jsp。但是，我甚至不想获得视图，而是要获得HTTP响应。

@RequestMapping(value = "/heroku/resources/", method = RequestMethod.POST)
    public  ModelAndView provision(final HttpServletRequest request){
            System.out.println("called! \n");
            JSONObject response = new JSONObject();
            response.put("id", 555);
            response.put("message", "Provision successful!");
            final Map<String, Object> result = new HashMap<String, Object>();
          return new ModelAndView("jsonView",result);   
    }

Answer 1

您缺少@responsebody

@RequestMapping(value = "/heroku/resources/", method = RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody ResponseEntity<JSONObject> provision(@RequestBody JSONObject body){
    System.out.println("called! \n");
    JSONObject response = new JSONObject();
    response.put("id", 555);
    response.put("message", "Provision successful!");
      return new ResponseEntity<JSONObject>(response,HttpStatus.OK);        
}
