Spring + Ibatis 事务为何不回滚？

Question

Spring ApplicationContext 配置文件：     <!-- 定义DataSource -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
        <property name="url" value="jdbc:oracle:thin:@10.132.224.203:1521:myorcl" />
        <property name="username" value="*****" />
        <property name="password" value="*****" />
    </bean>
    
    <bean id="sqlmapclient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="configLocation">
            <value>classpath:com/test/ibatis/sqlmap/sqlMapConfig.xml</value>
        </property>
        <property name="dataSource" ref="dataSource" />
    </bean>    <!-- Ibatis DAO 实现类 -->
    <bean id="iBatisDao" class="com.test.dao.impl.UserImpl">
        <property name="sqlMapClient">
            <ref local="sqlmapclient" />
        </property>
    </bean>    
         
    <!-- Struts Action类 注入业务类 -->
    <bean id="useraction" class="com.test.struts.action.UserAction">
    <property name="user" ref="user_service"></property>
    </bean>    <!-- 业务类 注入dao实现类 -->
    <bean id="user_service" class="com.test.struts.service.UserService">
        <property name="dao" ref="iBatisDao"></property>
    </bean>
        
    <!-- 事务管理 -->
    <bean id="transactionManage"
         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
             <property name="dataSource" ref="dataSource"></property>
     </bean>
    
    <!-- 装配事务 -->
    <bean id="transactionInterceptor"
     class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="target" ref="user_service"></property>
        <property name="transactionManager" ref="transactionManage"></property>
        <property name="transactionAttributes">
            <props>
                <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="*">PROPAGATION_REQUIRED,-MyException,-RemoteException,-SocketException</prop>
            </props>
        </property>
    </bean>
其中涉及的重要类： 
UserImpl 数据层实现类： public class UserImpl extends SqlMapClientDaoSupport implements IUserDao {    public void addUserInfo() {
        UserModel umodel = new UserModel();
        umodel.setId("4");
        umodel.setName("lalala");
        umodel.setPassword("123456789");
        umodel.setState(1);
        this.getSqlMapClientTemplate().insert(StaticSqlString.getADD_USER(), umodel);
        //故意再插入一条数据导致错误
        this.getSqlMapClientTemplate().insert(StaticSqlString.getADD_USER(), umodel);
    }    public List getUserInfo() {
        List list = null;
        list = this.getSqlMapClientTemplate().queryForList(StaticSqlString.getSELECT_ALL_USER());
        System.out.println(list.size());        
        return list;
    }
}UserService 业务类（事务控制）：     public List getUserInfo()
    {
        List list = null;
        list = dao.getUserInfo();
        return list;
    }
    
    public void addUser()throws RuntimeException{
        try{
            dao.addUserInfo();
        }catch(DataAccessException es){
            System.out.println("错误了");
                        //抛出自定义错误MyException，继承自RuntimeException
            throw new MyException(es.toString());
        }
    }
MyException：自定义错误类： public class MyException extends RuntimeException{
    public MyException(String msg){
        super(msg);
    }
}UserAction 中调用业务类方法新增数据：     public String execute() throws Exception {
        String type = request.getParameter("type").toString();
        if(type.equals("1")){
            List list = new ArrayList();
            list = user.getUserInfo();
            this.setUserlist(list);
        }else{
                user.addUser();
        }
        return "testok";
    }
但不知道为什么在Spring中装配的声明事务似乎同空气一般不起任何作用，不知道是哪里设置错误还是代码上出错了，我有些怀疑是事务控制层对应不上事务装配中指定的类，但又不是非常确定，还请高手帮忙看看是哪里的问题了？多谢多谢！！
