关于AOP记录日志的做法

记录日志类

package com.suning.sdipa.aop.log;import java.lang.annotation.ElementType;import java.lang.annotation.Retention;import java.lang.annotation.RetentionPolicy;import java.lang.annotation.Target;@Retention(RetentionPolicy.RUNTIME)@Target({ ElementType.METHOD, ElementType.TYPE })public @interface AdminLog {    /**     * 系统编码     */    String systemType() default "SDIPA";    /**     *      * 模块编码 <br>     */    String moduleType();    /**     * 操作类型     */    String operType();}

拦截器类
