Hibernate利用XDoclet自動生成配置文件

many-to-many為例，有Position和User兩張表，一個Position可以有多個Users，一個User也可以有多個 Position，中間的關聯表為 test_user_position 。通過在PO中加入XDoclet，自動生成hbm配置文件。不廢話，看代碼。

在Myeclipse中右鍵點擊項目，選擇“Properties"，從界面中選擇”Myeclipse/XDoclet"，點擊“Add Standard...”，添加“Standard Hibernate”，點擊OK，結束設置。

在項目中建立Hibernate.cfg.xml，配置好SessionFactory和數據源

右鍵點擊項目，選擇“Myeclipse/Run XDoclet"，將自動創建以上兩個類對應的hbm文件。

注意：創建完成的hbm文件存在問題，裡面有role和readonly屬性，將前者改為name，後者刪掉即可。
