我正在使用Hibernate 4和Postgresql數據庫。選擇查詢執行得很好,但是當涉及到更新查詢(插入)時根本不起作用。休眠正在提交但未保存

日誌沒有說任何關於錯誤的信息,一切似乎都沒有問題並且已經提交。我試圖使用DAO層來保存對象:

public void add(Role role) { 
    sessionFactory.openSession().save(role); 
} 

服務層:

@Transactional 
public void addNewRole(Role role) { 
    roleDao.add(role);  

} 

角色對象映射,SessionFactory的是沒有任何問題的注入。這裏是日誌說什麼:

測試程序:

public static void main(String[] args) { 

    ApplicationContext cx = new ClassPathXmlApplicationContext("spring/spring-all.xml"); 
    RoleService roleService = (RoleService) cx.getBean("roleService"); 

    Role role = new Role(); 
    role.setCode("TEST"); 
    role.setName("Test"); 
    role.setDescription("Test Role"); 

    roleService.addNewRole(role); 

} 

的對象不保存在物理數據庫呢?我檢查了數據庫用戶的權限,但它似乎擁有對所有操作的完全超級訪問權限!

可能是什麼原因?

如果您嘗試在沒有休眠的情況下運行類似的插入,它是否工作?你是否尊重所有非空,外鍵等約束? – 2014-09-28 07:34:29

正常的插入正在工作,所有的字段都被提交,除了主鍵以外沒有約束的普通表! – Hatem 2014-09-28 07:38:24

你可以測試你的休眠命令並在主鍵上添加一個值嗎?我沒有進入休眠狀態,我只是給出一些一般的想法。 – 2014-09-28 07:42:13

您正在DAO中打開一個未連接到當前Spring事務的新會話。不要這樣做。取而代之的是,獲取與當前事務相關的當前會話:

Session session = sessionfactory.getCurrentSession();

非常感謝,這是正確的答案,你節省了我的一天! – Hatem 2014-09-28 10:06:46
