标签:interface   reg   tac   one   保存数据   request   oid   add   spec   

由于直接拦截所有的controller所以需要spring.xml中添加
<aop:aspectj-autoproxy proxy-target-class="true" />  交由cglib代理。

使用只要在controller的method上加上
@ActionControllerLog(channel="web",action="user_register",title="用户注册",isSaveRequestData=true)
其中isSavveRequestData代表是否保存请求参数,默认为false。
