这个异常是因为，在hibernate事务管理中，你在service中写的方法，被hibernate列为了只读属性，只能从数据库中读取数据，不能进行增加和更新和删除操作。

这个是在配置文件中，已经说明的：

<!-- 声明式容器事务管理 --><tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="save*" propagation="REQUIRED" /><tx:method name="add*" propagation="REQUIRED" /><tx:method name="create*" propagation="REQUIRED" /><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="merge*" propagation="REQUIRED" /><tx:method name="del*" propagation="REQUIRED" /><tx:method name="remove*" propagation="REQUIRED" /><tx:method name="put*" propagation="REQUIRED" /><tx:method name="use*" propagation="REQUIRED" /><tx:method name="recordOperLog" propagation="REQUIRED" /><!--hibernate4必须配置为开启事务 否则 getCurrentSession()获取不到 --><tx:method name="get*" propagation="REQUIRED" read-only="true" /><tx:method name="count*" propagation="REQUIRED" read-only="true" /><tx:method name="find*" propagation="REQUIRED" read-only="true" /><tx:method name="list*" propagation="REQUIRED" read-only="true" /><tx:method name="*" read-only="true" /></tx:attributes></tx:advice><aop:config expose-proxy="true"><!-- 只对业务逻辑层实施事务 --><aop:pointcut id="txPointcut"expression="execution(* com.rxtmedia.base.service..*.*(..))" /><aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" /></aop:config>

我在service中使用的方法名是 ： public void toTop(...)  toTop 的方法名并不在声明事务容器管理里，只能匹配

<tx:method name="*" read-only="true" /> // 该方法是只读属性

/** * 置顶 */@Overridepublic void toTop(String id) {try {StrategyInfo strategy = strategyInfoDAO.findById(Long.valueOf(id));Byte priority = strategy.getPriority();

解决有两种办法：

1.更改配置文件。

<tx:method name="toTop" propagation="REQUIRED" />

建议最好不要这么做，首先配置文件在项目一开始的时候就会规划好，xml的配置文件也能规范程序员在service层开发时候的方法命名，再说这个配置文件一般都是你们经理配置好的，你若更改必须要经过经理的同意，其他人更新代码的时候 也要去更新配置文件，所以这样不推荐。

2.就是把自己的方法名称更改为符合规范的命名，不是只读属性的即可。比如  更新方法名为 updateStrategyToTop(...) {} ....
