【100分】【在线等】Spring+ibatis+ehcache MethodCacheInterceptor的invoke方法没有执行
小弟最新做一个项目 需要使用到Spring+ibatis+ehcache 参照网上的资料自己写了一些配置 可惜MethodCacheInterceptor的invoke方法始终没有执行。想请各位高人指点迷津
这个是Tomcat启动log信息 其中MethodCacheInterceptor已经被初始化了

[解决办法]
你先用普通 Java 调用 ClassPathXmlApplicationContext 整合看看能成功不
[解决办法]
建议检查下切面的代码是否正确
<bean id="lowFreMethodCachePointCut" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="advice" ref="lowFreMethodCacheInterceptor" />
