spring boot 自定义注解标签@interface记录系统访问日志AOP（好文章！！）

 自定义注解@interface：

package io.renren.common.annotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * 系统日志注解
 *
 * @author Mark [email protected]
 * @since 1.3.0 2017-03-08
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {

    String value() default "";
}

/**
 * 保存
 */
@SysLog("保存菜单")
public R save(@RequestBody SysMenuEntity menu){
        //数据校验
        verifyForm(menu);
        
        sysMenuService.insert(menu);
        
        return R.ok();
    }

 AOP：
