AOP注解无效，切面不执行的解决
想做一个api请求日志，想到使用aop，配置过程中遇到了一个坑，aop不起作用，
我的aop是这样的：

配置文件分成applicationContext.xml、applicationContext-mvc.xml还有mybatis和shiro的
web.xml配置：

我把<aop:aspectj-autoproxy proxy-target-class="true"/>写在applicationContext中，把<context:component-scan> 和 <mvc:annotation-driven>写在applicationContext-mvc中，发现aop没有执行，后来经过尝试发现，因为在初始化DispatchServlet的时候加载了mvc的配置，但是aop的代理却没有加载，导致其不能执行，我猜测是因为spring默认bean是单例的，
对已经初始化的bean容器不在做后续处理，由于是先加载的mvc所以是aop失效，我把aop代理的那个放到mvc中，aop就能执行了，不知道我的猜测对不对，还望大神赐教
另一个问题：
springmvc在controller层使用aop切面不成功解决
需要在配置文件中加入

<aop:aspectj-autoproxy proxy-target-class="true" /> |
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
