java面向切面日志处理

1、注解Log类

package org.monitor.annotation;

import org.monitor.enums.BusinessType;
import org.monitor.enums.OperatorType;

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;

@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;
}

2、切面类

3、日志处理类

package org.monitor.bean;

import java.util.Date;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;

@Data
@TableName("sys_oper_log")
public class SysOperLog {
    private static final long serialVersionUID = 1L;

    /** 日志主键 */
    @TableId(type = IdType.AUTO)
    private Long operId;

    /** 操作模块 */
    private String title;

    /** 业务类型（0其它 1新增 2修改 3删除） */
    private Integer businessType;

    /** 业务类型数组 */
    private Integer[] businessTypes;

    /** 请求方法 */
    private String method;

    /** 请求方式 */
    private String requestMethod;

    /** 操作类别（0其它 1后台用户 2手机端用户） */
    private Integer operatorType;

    /** 操作人员 */
    private String operName;

    /** 部门名称 */
    private String deptName;

    /** 请求url */
    private String operUrl;

    /** 操作地址 */
    private String operIp;

    /** 请求参数 */
    private String operParam;

    /** 返回参数 */
    private String jsonResult;

    /** 操作状态（0正常 1异常） */
    private Integer status;

    /** 错误消息 */
    private String errorMsg;

    /** 操作时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date operTime;


}

4、数据库

CREATE TABLE `sys_oper_log` (
`oper_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '日志主键',
`title` varchar(50) DEFAULT '' COMMENT '模块标题',
`business_type` int(2) DEFAULT '0' COMMENT '业务类型（0其它 1新增 2修改 3删除）',
`method` varchar(100) DEFAULT '' COMMENT '方法名称',

`operator_type` int(1) DEFAULT '0' COMMENT '操作类别（0其它 1后台用户 2手机端用户）',
`oper_name` varchar(50) DEFAULT '' COMMENT '操作人员',
`dept_name` varchar(50) DEFAULT '' COMMENT '部门名称',
`oper_url` varchar(255) DEFAULT '' COMMENT '请求URL',
`oper_ip` varchar(50) DEFAULT '' COMMENT '主机地址',
`oper_location` varchar(255) DEFAULT '' COMMENT '操作地点',
`oper_param` varchar(2000) DEFAULT '' COMMENT '请求参数',

`oper_time` datetime DEFAULT NULL COMMENT '操作时间',
PRIMARY KEY (`oper_id`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 COMMENT='操作日志记录'
