springmvc出现 No converter found for return value of type错误

Posted 2023-02-17 Chris-Chang

handler控制器如下

    @ResponseBody
    @RequestMapping("/sendCompose/object.json")
    public ResultEntity<Student> testReceiveComposeObject(@RequestBody Student student)
        logger.info(student.toString());
        //将“查询”到的Student对象封装到ResultEntity中返回
        ResultEntity<Student> resultEntity = ResultEntity.successWithData(student);
        return resultEntity;
    

原因是ResultEntity没有写set和get方法。
