xml配置文件如下：

        <property name="dataSource" ref="dataSource"/>  
        </bean>  

       <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">  

        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>  

        <property name="url" value="jdbc:mysql://127.0.0.1/student"/>  

        <property name="username" value="root"/>  

        <property name="password" value="root"/>  

    </bean>  

<!--配置哪些方法,什么情况下需要回滚-->


tx:attributes

<!--当代理的service层中的方法抛出异常的时候才回滚,必须加rollback-for参数-->





<!--除了上面标识的方法,其他方法全是只读方法 -->


/tx:attributes

/tx:advice

<!-- 配置哪些类的方法需要进行事务管理 -->







/aop:config

StudentDaoImpl 里面没有sqlMapClient 的定义

你好！


这不是已经注入进去了吗？
继承 的是SqlMapClientDaoSupport 这个类

    Bean property 'driverClassName' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
