我使用 url 直接在浏览器中请求控制器,但我得到'{}' an empty object 。我确定控制器的返回不为空,但页面得到一个空响应。
我还使用工作项目中的工作配置文件构建了一个新项目,但是在新项目中,请求后仍然得到空响应。
我不知道原因,工作项目的任何事情都是一样的。
代码如下。
控制器,只是一个简单的测试
@Controller
@RequestMapping("/layout")
public class LayoutController {
@Autowired
LayoutServer layoutServer;
@RequestMapping("/test1")
@ResponseBody
public ResultUtil test(){
ResultUtil resultUtil=ResultUtil.success(200,"this is data","this is page data");
System.out.println(resultUtil);
return resultUtil;
}
}
请求结果,抱歉上传图片失败。它只是得到'{}'。 控制台打印工作正常
配置跟随。
