發生原因：
1. Lazy功能預設為true啟動
2. Session已經Close
由於Lazy功能會讓Object在真的需要使用時才會像資料庫讀取資料，假設我們已經Session關閉後，要取得Object相關聯的外部物件就會發生此Exception。

解決辦法1： 將Lazy設為false，但校能可能會不好

解決辦法2： 在關閉Session前使用Hibernate.initialize(物件)，纖纖物件容器載入。

     ex:

public TestFrame extends java.swing.JFrame
{
    public TestFrame()
    {
        //配置Components
    }
}

2.建立各自GUI 元件事件的Event Handler Class實作特別的Listener

ex:

private class TextFieldHandler implements ActionLister
{
   public void actionPerformed(ActionEvent e)
    {
        //Components行為處理
    }
}

3. 將各自GUI 元件事件Object註冊到各自GUI 元件Object的Listener

ex:

public TestFrame extends java.swing.JFrame
{
    public TestFrame()
    {
        //配置Components
       TextField textfield1=TextField();
       
       //為各自Components註冊設定Event Handler
       TextFieldHandler textfieldhandler1=new TextFieldHandler ():
       textfield1.addActionLister(textfieldhandler1) ;
    }
}
