无法在 MYSQL 中回滚 BMT EJB UserTransaction

Question

我的应用程序使用 Struts2、EJB3 会话无状态 bean、JDBC、MYSQL。 我无法在异常情况下回滚完整的事务。 我在 EJB3 Statemless bean 中使用了 BMT、用户事务，并使用了 JDBC，数据库是 MYSQL。 我正在插入三条记录，一条在父表中，两条记录在子表中。 我在插入父级和一个子级后模拟异常，用户事务能够从子级回滚，但不能从父级回滚。 请指教

请在EJB下面找到代码

@Stateless
@Remote
@RemoteBinding(jndiBinding = AppConstants.JNDI_BINDING_CTRADE)
@TransactionManagement(value=TransactionManagementType.BEAN)
public class CManager implements CManagement {


        @Override
        public void saveDetails(String sessionId) {
            try {
                // TODO Auto-generated method stub
                 userTransaction.begin();
                CInterface cInterface = createCInstance(sessionId, true);
                cInterface.saveDetails3(sessionId);
                cInterface.saveDetails2(sessionId);
                String st=null;
                if(st.equals("test")); // So fake a null pointer
                cInterface.saveDetails1(sessionId);             
                 userTransaction.commit();
            } catch (Exception e) {
                 try {
                    userTransaction.rollback();
                    e.printStackTrace();
                } catch (IllegalStateException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                } catch (SecurityException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                } catch (SystemException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }
            }
