</beans>测试代码如下:
package test;import java.util.Date;
import java.util.List;import org.hibernate.Session;import comm.data.Admin;
import comm.data.AdminDAO;
import comm.data.TestTable;
import comm.data.TestTableDAO;import comm.factory.DmsSession;
import comm.factory.SpringFactory;import junit.framework.TestCase;import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;public class TestSearch extends TestCase {
    public void testSer(){
     Session session=new DmsSession().getSession();
     AdminDAO ad=(AdminDAO)SpringFactory.getInstance().getBean("AdminDAO");
     List list=ad.findAll();
    
     session.close();
     assert(list.size()>0);
     System.out.println("222");
    }
    @Transactional
    public void testUpdate(){
     Session session=new DmsSession().getSession();
     Admin adm=new Admin();
     TestTable  ttbean=new TestTable();
     adm.setLoginName("3222");//其余两值置空，使其报错测试事务控制能否回滚
     ttbean.setName("ss3asdf");
     ttbean.setCode((long)2134);
     ttbean.setCreateDate(new Date());
     AdminDAO ad=(AdminDAO)SpringFactory.getInstance().getBean("AdminDAO");
     TestTableDAO tt=(TestTableDAO)SpringFactory.getInstance().getBean("TestTableDAO");
    
    
     tt.save(ttbean);
     ad.save(adm);
    
       
     session.close();
    
     System.out.println("222");
    }
}
结果报这个错：

</aop:config>这块代码没问题能执行。但是事务却无法控制执行了。
非常郁闷各位大大看看怎么回事！

Answer 1

java.lang.ClassCastException: $Proxy4 cannot be cast to comm.data.AdminDAO
at test.TestSearch.testUpdate(TestSearch.java:38)代码强制转换错误咯...

Answer 2

事务回滚失败test表还是插进去了

Answer 3

AdminDAO ad=(AdminDAO)SpringFactory.getInstance().getBean("AdminDAO");
38行有问题，类强制转换的原因，查看下你的类AdminDAO 

Answer 4

AdminDAO可能有字段个数没有写全或GET SET方法没生成全吧 检查下

Answer 5

哦！那个问题没了。换成接口就没事儿了。但是有个问题我想问。spring事务管理无法对多表操作进行管理吗？比如我有两个表admin和忒 test表一个表我让他正常插入。另一个表制造一个异常。放在同一个事务里。结果正常的表依然能插入进去。事务是只能管理一个表的操作还是？

Answer 6

感觉还是spring事务和hibernate结合问题造成的，还是好好看看怎么结合，好像提示有代理类，但是你配置又没有用代理，看来是配置问题

Answer 7

<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
<aop:config>
<aop:pointcut id="serviceMethod"
expression="execution(* comm.data.*.*(..))" />
<aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice" />
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
 <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="del*" propagation="REQUIRED" />
          
            <tx:method name="*" read-only="true" />
  
</tx:attributes>
</tx:advice>

Answer 8

去掉<aop:config>
 <aop:pointcut id="serviceMethod"
 expression="execution(* comm.data..*.*(..))" />
 <aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice" />
 </aop:config>这块代码没问题能执行,能打印出sql语句，但是数据库中没有变化，然后加上就会出现错误
