日志切面思路(ruoyivue)

日志持久化模块的设计思路:

1. 为什么设计日志持久化模块?

日志持久化到mysql可以更方便,快捷的让开发,运维人员定位到错误;

2. 日志持久化功能设计的大概思路

参照目前比较流行的ruoyi-vue后台管理框架,采用注解,切面的方式,将日志持久化到msql

3. 日志持久化的内容(表的设计)

4. 代码分析

自定义注解

package com.ruoyi.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;
import com.ruoyi.common.enums.BusinessType;
import com.ruoyi.common.enums.OperatorType;

/**
 * 自定义操作日志记录注解
 * 
 * @author ruoyi
 *
 */
@Target({ ElementType.PARAMETER, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log
{
    /**
     * 模块 
     */
    public String title() default "";

    /**
     * 功能
     */
    public BusinessType businessType() default BusinessType.OTHER;

    /**
     * 操作人类别
     */
    public OperatorType operatorType() default OperatorType.MANAGE;

    /**
     * 是否保存请求的参数
     */
    public boolean isSaveRequestData() default true;

    /**
     * 是否保存响应的参数
     */
    public boolean isSaveResponseData() default true;
}

切面

5. 使用方式

6. 数据示范
