Spring @事务性批注不工作

我试图在数据库中保存一个

TestEntity

对象。正在执行代码并创建实体的Id，但实体未持久化到数据库（未插入行）：

<!-- Our service layer components -->
<context:component-scan base-package="com.homecare" />
<!-- <context:component-scan base-package="com.homecare.persistance.repository" /> -->


 <!-- enable @Transactional Annotation -->



<!-- data source with c3p0 -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
      <property name="driverClassName" value="org.postgresql.Driver" />
      <property name="url" value="jdbc:postgresql://localhost:5433/My_DB" />
      <property name="username" value="postgres" />
      <property name="password" value="password" />
   </bean>

   <bean id="SessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="packagesToScan" value="com.homecare.persistance.resource"></property>   <!-- yet to defined place where to scan> -->
      <property name="hibernateProperties">

                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
      <property name="sessionFactory" ref="SessionFactory" />
   </bean>
</beans>

从3行（beginTranslation、flush、commit）中删除注释可以解决问题，但是为什么

@Transactional

注释在这里不起作用

使用autowired as定义sessionfactory对象

 <!-- enable @Transactional Annotation -->

</beans>

@Autowired
Private SessionFactory sessionFactory;

并将会话对象作为

<context:component-scan base-package="com.homecare" />
<!-- <context:component-scan base-package="com.homecare.persistance.repository" /> -->


 <!-- enable @Transactional Annotation -->

   </bean>
</beans>

Session session = sessionFactory.getCurrentSession();

现在执行session.save（对象）

<!-- Our service layer components -->
<context:component-scan base-package="com.homecare" />
<!-- <context:component-scan base-package="com.homecare.persistance.repository" /> -->


 <!-- enable @Transactional Annotation -->

根据代码中的spring配置，sessionFactory与transactionManager相关联。因此，当事务成功完成时，在会话（与事务管理器关联）中执行的所有更改都将在db中提交。

尝试覆盖getSession（）方法：

<!-- Our service layer components -->
<context:component-scan base-package="com.homecare" />
<!-- <context:component-scan base-package="com.homecare.persistance.repository" /> -->


 <!-- enable @Transactional Annotation -->



<!-- data source with c3p0 -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
      <property name="driverClassName" value="org.postgresql.Driver" />
      <property name="url" value="jdbc:postgresql://localhost:5433/My_DB" />
      <property name="username" value="postgres" />
      <property name="password" value="password" />
   </bean>

   <bean id="SessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="packagesToScan" value="com.homecare.persistance.resource"></property>   <!-- yet to defined place where to scan> -->
      <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
      <property name="sessionFactory" ref="SessionFactory" />
   </bean>
</beans>

我没有看到启用事务管理的

，它在spring xml文件中（最后三个标记）：我只使用Autowired注释注入SessionFactory对象。而事务注释也可以与openSession（）一起使用，那么为什么要使用SessionFactory.getCurrentSession（）。我还以注入SessionFactory对象的方式更新了代码。SessionFactory.openSession（）总是打开一个新会话，在完成操作后必须关闭该会话。getCurrentSession（）返回绑定到上下文的会话-您不需要关闭它。是的，这很好。但我的问题不同。我的实际问题是为什么spring事务注释功能不起作用？您是否尝试通过更改为sessionFactory.getCurrentSession（）来测试事务提交？。如果仍然不工作，您可以添加true。谢谢Vijay。它在sessionFactory.getCurrentSession（）上运行良好，并且不使用true标记。但这让我有些怀疑。第一个问题是：为什么sessionFactory.openSession（）不能使用它？第二个是：为了使sessionFactory.getCurrentSession（）工作，我们假设在SpringXML文件中添加线程。但在这里，我没有添加它，但仍在工作。您能帮我解决这个问题吗？在进行上述更改之后，实体仍然没有提交到数据库。
