<sqlMapConfig>
    <sqlMap resource="com/angi/ibatis/maps/User.xml" />
</sqlMapConfig>
以上配置省去了transactionManager的配置，就会使用external（外部）事务管理（ExternalTransaction），即等同如下配置：
<sqlMapConfig>
    <transactionManager type="EXTERNAL">
                <!--这个数据源其实没有什么意义，还是取上面的省略方式吧-->
        <dataSource type="DBCP">
        </dataSource>
    </transactionManager>
    <sqlMap resource="com/angi/ibatis/maps/User.xml" />
</sqlMapConfig>
1、TransactionProxyFactoryBean

Java代码：
@Transactional
    public void doTransaction() {
        User user = new User();
        user.setName("11111");
        user.setSex(1);
        userDao.saveUser(user);
        User user1 = new User();
        user1.setName("Angikkk");
        user1.setSex(1);
        userDao.saveUser(user1);
