关于Spring事务管理问题的探讨

Question

大家好,我最近几天一直在调spring事务.可事务不回滚的问题一直困绕着我.
说一下我的大概思路,在Service层,分别调用两个DAO层的业务方法.实现保存功能.

我采用的数据库是Sql Server2000

Service层代码:

public class UserService implements IUserService {
 private IUserDAO userDAO;
 private IAddressDAO addressDAO;
 public void saveUserAndAddress(User user, Address address) {

//我想要实现的效果: 当userDAO执行成功,并且addressDAO执行成功,则数据库中对应USER表,及ADDRESS保存数据.

//如果userDAO执行失败,或addressDAO执行失败,则USER表,及ADDRESS表不保存数据
  userDAO.saveUser(user);
  addressDAO.saveAddress(address);
 }
         
         //下面的get / set userDAO , addressDAO方法略
           ....
UserDAO层代码:
public class UserDAOImpl implements IUserDAO {
 private JdbcTemplate jdbcTemplate;
 public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
  this.jdbcTemplate = jdbcTemplate;
 }
 public void saveUser(User user) {
  String sql = "insert into ma_user_info (id , user_name , pass_word) values("+user.getId()+",'"+user.getUsername()+"' ,'"+user.getPassword()+"')";
  jdbcTemplate.update(sql);
 }
}
AddressDAO层代码:
public class AddressDAOImpl implements IAddressDAO {
 private JdbcTemplate jdbcTemplate;
 public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
  this.jdbcTemplate = jdbcTemplate;
 }
 public void saveAddress(Address address)  {
  String sql = "insert into ma_address_info (i,address)values("+address.getId()+",'"+address.getAddName()+"')";;
  jdbcTemplate.update(sql) ;
 }
}

beans-config.xml配置:

 <bean id="transactionDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
  <property name="url" value="jdbc:sqlserver://127.0.0.1:1433;databaseName=hibernate_research" />
  <property name="username" value="sa" />
  <property name="password" value="sa" />
 </bean>
 <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" >
  <constructor-arg ref="transactionDataSource" />
 </bean>
 <!-- data access layer -->
 <bean id="transactionUserDAO" class="com.transaction.dao.user.UserDAOImpl" >
  <property name="jdbcTemplate" ref="jdbcTemplate" />
 </bean>
 <bean id="transactionAddressDAO" class="com.transaction.dao.address.AddressDAOImpl" >
  <property name="jdbcTemplate" ref="jdbcTemplate" />
 </bean>
 <!-- business logic layer -->
 <bean id="transactionUserService" class="com.transaction.service.UserService">
  <property name="userDAO" ref="transactionUserDAO" />
  <property name="addressDAO" ref="transactionAddressDAO" />
 </bean>
 <!-- proxy -->
 <bean id="transactionUserServiceProxyBean" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  <property name="proxyInterfaces">
   <list>
    <value>com.transaction.service.IUserService</value>
   </list>
  </property>
  <property name="target" ref="transactionUserService" />
  <property name="transactionAttributes">
   <props>
    <prop key="save*">PROPAGATION_REQUIRED,-java.lang.Exception</prop>
   </props>
  </property>
 </bean>

最后的main方法测试类代码:

 public static void main(String[] args) {
  ApplicationContext context = new ClassPathXmlApplicationContext("beans-config.xml");
  IUserService userService = (IUserService)context.getBean("transactionUserServiceProxyBean");
  User user = new User();
  user.setId(100);
  user.setUsername("username_100");
  user.setPassword("password_100");
  Address address = new Address();
  address.setId(100);
  address.setAddName("address_100");
  userService.saveUserAndAddress(user, address);

}

请各位不吝指教.万分感谢!

你的配置错了，你好像都没声明使用spring的事务代理机制，你最好把完整的配置文件发出来，如果你需要spring事务代理，你需要申明在application*.xml文件中的，比如
[code="java"] class="org.springframework.orm.hibernate.HibernateTransactionManager">



[/code]

[code="java"] <!-- Transactional proxy for the services -->
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
lazy-init="true">





PROPAGATION_REQUIRED
PROPAGATION_REQUIRED
PROPAGATION_REQUIRED
PROPAGATION_REQUIRED
PROPAGATION_REQUIRED
PROPAGATION_REQUIRED
PROPAGATION_REQUIRED


[/code]

     下面的service类声明了parent调用的是spring的事务代理，这样才会回滚啊。

[code="java"]


class="com.stt.apps.doms.service.impl.AdminServiceImpl"
autowire="byName">

</bean>

[/code]
