Spring MVC @Transactional註解方式事務無效的解決方法

首先看了配置文件關於事務管理都沒有問題，然後在service的實現業務類方法加上@Transactional註解，發現事務沒有生效，正常情況下應該會有數據庫回滾操作。

查到原因爲：
Spring容器優先加載由ServletContextListener（對應spring-mybatis.xml）產生的父容器，而SpringMVC（對應spring-mvc.xml）產生的是子容器。子容器Controller進行掃描裝配時裝配的@Service註解的實例是沒有經過事務加強處理，即沒有事務處理能力的Service，而父容器進行初始化的Service是保證事務的增強處理能力的。如果不在子容器中將Service exclude掉，此時得到的將是原樣的無事務處理能力的Service。
修改 spring-mvc.xml

  <context:component-scan base-package="com.XXX">
   <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />    
  </context:component-scan>

測試事務有效：

@Override
    @Transactional
    public void testTransactional() {
        // TODO Auto-generated method stub
            //正確的sql語句
            ckFormDao.testTransactional1();
            //錯誤的sql語句
            ckFormDao.testTransactional2();
    }
