bae项目链接数据好难
com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: Cannot load connection class because of underlying exception: 'java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)'.在bae项目中执行个save· 就报错· 求大神指点·!!!

1: LocalSessionFactoryBean取代了HibernateSessionFactory
作用: 用来加载hibernate配置文件, 管理连接
-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 2: 事务管理器,管理sessionFacotry -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 3: 配置通知
AOP: 面向切面编程, 首选需要一个切面, 前面里面的方法 就叫通知, 向哪里切 就要切入表达式
-->
<tx:advice id="advice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>
<!-- 4:配置切入表达式: 只是确定 包.类.方法, 上面的 advice 才能确认每个方法是否需要切入事务,所以两者结合-->
<aop:config>
<aop:pointcut expression="execution(* com.tuotem4.wxfw.service.impl.*.*(..))" id="pointcut"/>
<aop:advisor advice-ref="advice" pointcut-ref="pointcut"/>
</aop:config>
</beans>
补充:Java , Java EE
