ここに私のSpring MVCコントローラーがあります：

    @Autowired
    StudentService studentService;

    @RequestMapping(value="/editing-popup", method = RequestMethod.GET)
    public String index() {
        return "hello";
    }


    @RequestMapping(value = "/editing-popup/read", method = RequestMethod.POST)

        target.setId(Integer.parseInt(model.get("id").toString()));

        studentService.DeleteEntity(target);

        return target;
    }




}

問題は、剣道のウェブサイトの例がこのコードを使用しているときにグリッドが空であることです。

readurl は機能しませんが、作成 URL は正しく機能しています! 挿入ボタン (グリッド上) を押すと、新しいレコードを追加するためのポップアップウィンドウが表示され、そのボタンをクリックすると、データベースにレコードが挿入されます。

問題はどこだ？！
