上面是报错信息

下面是解决方案:

查看mybatis 的配置文件

找到 tx:advice关键字

<!-- 配置事务增强，事务如何切入 --><tx:advice id="txAdvice" transaction-manager="transactionManager">    <tx:attributes>        <!-- 所有方法都是事务方法 -->        <tx:method name="*"/>        <!-- 以get开始的所有方法都是事务方法（调优：只读） -->        <tx:method name="get*" read-only="true"/>    </tx:attributes></tx:advice>

如果你的方法名,跟我的方法名 类似于 getAll 此时,程序会将此方法设置为read-only 的事务操作.会报如上错误.

解决方法:

修改方法名 getAll 为GetALL 就不会报错了,并且正常运行.

切记,按照上面tx:advice 配置的所有会操作数据库写入的类似于update insert操作均会设置为read-only
