void 方法写会浏览器json数据 方便复制粘贴

@GetMapping("/test")
public void test(HttpServletResponse response) throws IOException {
     JSONObject jsonObject =new JSONObject();
     jsonObject.put("code","400");
     jsonObject.put("msg","你没有相关权限!");
     response.setStatus(500);
     response.setCharacterEncoding("utf-8");
     response.setHeader("Content-Type","application/json;charset=utf-8");
     response.setContentType("application/json;charset=utf-8");
     new ObjectMapper().writeValue(response.getWriter(),jsonObject);
}
