我有以下方法，在调用callBothMethodInvocation()方法后，我期待用户插入时执行insertUser()将回滚，因为 insertUserWithException() 发生异常。但是，当我检查数据库用户表时，表中存在实体。我错过了什么？我发现了类似的问题http://forum.springsource.org/showthread.php?108015-JDBC-Transaction-inner-methods-and-rollback但找不到确切的解决方案。

@Transactional(rollbackFor=Exception.class)    
private void callBothMethodInvocation() throws Exception {
    insertUser();
    insertUserWithException();      
}


public void insertUserWithException() throws Exception{
    throw new Exception("fake exception for rollback");
}

@Transactional(rollbackFor=Exception.class) 
public void insertUser(){
    int id = (int) (System.currentTimeMillis()%1000);
    System.out.println("Insert user id:"+id);
    User user = new User(id,"Test",22);
    testDao.insertUser(user);
}

弹簧配置：

您需要在 context.xml 中启用 Spring 事务

<tx:annotation-driven />
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

这是一个工作测试

class X {
    @Autowired
    DataSource ds;

    @Transactional(rollbackFor = Exception.class)
    public void insert() throws Exception {
        new JdbcTemplate(ds).update("insert into t1 (c1) values ('1')");
        throw new Exception();
    }
}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/transactions.xml")
public class Transactions {
    @Autowired
    X x;

    @Test
    public void test() throws Exception {
        x.insert();
    }
}

交易.xml

xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
        ">
<context:annotation-config />

<bean class="X" />

<tx:annotation-driven />

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="url" value="jdbc:mysql://localhost/test" />
    <property name="username" value="root" />
    <property name="password" value="root" />
</bean>

看起来您没有配置 TransactionManager 或无法获取@Transactional.

尝试添加<tx:annotation-driven/>一个JpaTransactionManager名为transactionManager.
