Question

每次在运行程序的时候，都会提示这样的错误，但是数据可以正常的插入数据库，不知道是什么原因，请各位执教了，谢谢，分不够立刻加！错误：

Answer 2

Unable to proxy method [public final 
大概是代理类不能重写final方法

Answer 3

这只是警告而已..不是错误...Cglib2AopProxy,可能你aop:pointcut声明包含了无法代理的method,也就是hibernateDAOSupport里那些final method,,所以报这个警告

Answer 4

 <bean id="Loginproxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
 abstract="true">这里加了一个 abstract="true"
一、
你不要采用：<property name="target">
<ref local="LoginDAO"/>
</property>这种方式来写。
可以采用 <bean id="loginService" parent="transactionProxy">
<property name="target">
<bean class="ssh.LoginServiceImpl"
autowire="byName" />
</property>
</bean>二、你的事务控制最好放在Service层来处理，而不是DAO层。三、你没有用到事务啊。加上一个-Exception,来捕获异常处理你的事务控制回滚等操作。

Answer 5

TransactionProxyFactoryBean返回不了新建的代理
由于getSessionFactory()是final方法，所以无法对它进行织入其实你完全可以把AOP去掉，不用代理来做，或者即使你需要用代理类管理事务的话，忽略这个警告，也可以正常运行，因为你没有织入逻辑，所以警告提示不会生成新的代理类对象，而是直接把参数丢给原始对象来运行，结果不会有问题！

Answer 6

加了一个 abstract="true" 也不行而且连数据也写不进去了，
提示错误：Exception in thread "main" org.springframework.beans.factory.BeanIsAbstractException: Error creating bean with name 'Loginproxy': Bean definition is abstract

 <bean id="sessionfactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation"
            value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
sessionfactory---->换成sessionFactory试试看吧,我才刚写好,还没有运行 过.
