下面是Dao实现类代码：
package spring_hibernate.dao.impl;import java.util.List;import org.hibernate.LockMode;
import org.hibernate.criterion.DetachedCriteria;
import org.springframework.orm.hibernate3.HibernateTemplate;import spring_hibernate.dao.IMessageDao;
import spring_hibernate.entity.Message;public class MessageDaoImpl implements IMessageDao{
private HibernateTemplate hibernateTemplate;

public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
} public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
} public void addMessage(Message message) throws RuntimeException{
hibernateTemplate.save(message);
int a = 10 /0;
hibernateTemplate.save(message);
}

public void deleteMessage(Long id) {
hibernateTemplate.delete(searchMessageById(id), LockMode.NONE);
}

public List<Message> searchAllMessage() {
return hibernateTemplate.findByCriteria(DetachedCriteria.forClass(Message.class));
}

public Message searchMessageById(Long id) {
return hibernateTemplate.load(Message.class, id);
}

public void updateMessage(Message message) {
hibernateTemplate.update(message);
}
}下面是service实现类代码：
public class MessageServiceImpl implements IMessageService{
private IMessageDao messageDao;
public IMessageDao getMessageDao() {
return messageDao;
}
public void setMessageDao(IMessageDao messageDao) {
this.messageDao = messageDao;
}
@Override
public void addMessage(Message message) {
messageDao.addMessage(message);

}
下面是测试类代码：
public class Test {
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/spring_hibernate/config/spring/applicationcontext.xml");
IMessageService messageService = (MessageServiceImpl)applicationContext.getBean("messageService");
System.out.println(applicationContext.getBean("messageService").getClass());
Message message = new Message("测试标题","测试作者","神马都是浮云！",new Date());
messageService.addMessage(message);
}
}
我在dao层人为导致代码异常，但是事务还是提交了，请高手解答，为什么事务不起作用，很郁闷！

Answer 1

这段代码中可以看出来你的proxy中是针对*ServiceImpl的bean进行代理的，你可以尝试写*Service，，bean名称都要以*Service格式定义

Answer 2

根据你的建议，我把MessageServiceImpl来更名为MessageService,applicationcontext.xml中配置更改如下：<bean id="autoTransactionProxy" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
     <property name="beanNames">
     <list>
     <value>*Service</value>
     </list>
     </property>
     <property name="interceptorNames">
     <list>
     <value>transactionInterceptor</value>
     </list>
     </property>
    </bean>更改后，运行数据没有插入数据库，但是抛异常，不是我人为抛出的异常，貌似是类型转换异常，请指教！
Exception in thread "main" java.lang.ClassCastException: $Proxy0 cannot be cast to spring_hibernate.service.impl.MessageService
at spring_hibernate.test.Test.main(Test.java:15)

Answer 3

spring配置文件改成：<bean id="autoTransactionProxy" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
        <property name="beanNames">
            <list>
                <value>MessageService</value>
            </list>
        </property>
        <property name="interceptorNames">
            <list>
                <value>transactionInterceptor</value>
            </list>
        </property>
    </bean>
后，运行，数据仍然还是插进去了，事务没回滚，郁闷，还望大家多多指教！郁闷2天了，我感激不尽！

Answer 4

经过我自己的不懈努力，还是我自己解决了，哈哈！谢谢loveliy520的回复！
