（已于2018年01月04日更新了一个优化版，里面附带源码，地址为：http://www.cnblogs.com/leifei/p/8194644.html ）
前几天做系统日志记录的功能，一个操作调一次记录方法，每次还得去收集参数等等，太尼玛烦了。在程序员的世界里，当你的一个功能重复出现多次，就应该想想肯定有更简单的实现方法。于是果断搜索各种资料，终于搞定了，现在上代码
环境: SpringMvc + myBatis

1.自定义注解类 ArchivesLog.java(获取Controller描述用的)

3.spring 注入
<!--指定扫描目录-->
<context:component-scan base-package="com.noahwm" /> <aop:aspectj-autoproxy proxy-target-class="true" /> <!--将日志类注入到bean中。-->
<bean id="logAspect" class="com.noahwm.uomp.archives.common.ArchivesLogAspect"></bean> <aop:config>
<!--调用日志类-->
<aop:aspect id="LogAspect" ref="logAspect">
<!--配置在controller包下所有的类在调用之前都会被拦截-->
<aop:pointcut id="log" expression="execution(* com.noahwm.uomp.archives.controller.*.*(..))"/>
<!-- 方法前触发 --><aop:before pointcut-ref="log" method="before"/>
<!-- 方法后触发 --><aop:after pointcut-ref="log" method="after"/>
<!-- 环绕触发 <aop:around pointcut-ref="log" method="around"/> -->
</aop:aspect>
</aop:config>
3.调用(设置Controller描述)
@RequestMapping(value="/fileQuery")
@ArchivesLog(operationType="查询操作:",operationName="查询文件")
public ModelAndView fileQuery(HttpServletRequest request,HttpServletResponse response){ return new ModelAndView("archives/fileQuery");
}
