Question

我正在使用@Transactional注释来测试通过Spring应用程序将一些数据插入到其中一个表中。我的测试成功，但我没有看到任何数据插入到表中。

以下是相关的代码段：

MyTest的：

@TransactionConfiguration(transactionManager="MyTxManager")
@Transactional
public class MyTest {
    @Autowired
    private DataProvider provider;

    @Test
    @Transactional
    void testInsert() {
        Order purchaseOrder = new Order("ID1", "LER", "VDR1", 0, );
        provider.addRow(purchaseOrder);
    }

}

的DataProvider：

public class DataProvider extends DatabaseProvider {

    // some stuff...
    @Transactional
    public void insertRow(Order purchaseOrder) {
        /* 
         * SessionFactory is got through autowiring 
         * and is working perfectly fine.
         */
        Session session = sessionFactory.getCurrentSession();

        // This should save the row into the table - which it doesn't :(
        session.save(purchaseOrder);

    }

}

信息providers.xml

<bean id="DataProvider" class="com.util.DataProvider">
    <property name="sessionFactory" ref="MySessionFactory" />
</bean>

hibernate.xml包含会话工厂的配置

 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
      parent="AbstractSessionFactory" depends-on="EnvironmentHelper">
    <property name="hibernateProperties">
      <props>
         <prop key="hibernate.connection.autocommit">true</prop>
         <prop key="hibernate.connection.provider_class">com.hibernate.ConnectionPool</prop>
         <prop key="hibernate.connection.driver_class">${driverClassName}</prop>
         <prop key="hibernate.connection.url">${databaseURL}</prop>
         <prop key="hibernate.connection.username">${databaseUsername}</prop>
         <prop key="hibernate.connection.password">${databasePassword}</prop>

         <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
         <prop key="hibernate.default_schema">${databaseDefaultSchema}</prop>
      </props>
    </property>
</bean>

<!-- Use Spring transactions for Hibernate -->
<tx:annotation-driven transaction-manager="MyTxManager" mode='proxy' proxy-target-class='true'/>

<bean id="MyTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
   <property name="sessionFactory" ref="MySessionFactory" />
</bean>    
</beans>

Answer 1

我认为回滚交易的问题。请参见此处defaultRollback方法。试试这样：

@TransactionConfiguration(transactionManager="MyTxManager", defaultRollback=false)

Answer 2

你的问题是MyProvider myProviderInstance = new MyProvider(); myProviderInstance 不是由Spring容器维护的，你只是新建它，所以Spring无法对它做任何事情，肯定是事务没有'工作。你应该在Spring applicationcontext.xml中配置bean并用ApplicationtContext加载它，你可以在谷歌之后找到几十个样本。因为你使用Mysql，你应该确保使用innerDB模式或者mysql不支持该事务。

Answer 3

将行<tx:annotation-driven/>添加到弹簧配置

使用hibernate @Transactional插入表中
