SpringBoot_操作日志记录

SpringBoot使用AOP统一处理日志

应用(记录用户操作日志): 有时候我们需要处理一些请求日志，或者对某些方法进行一些监控，如果出现例外情况应该进行怎么样的处理，现在，我们从spring boot中引入AOP

 

1、开发准备

环境：idea、jdk 1.8、springboot、mysql

1.2 日志表

准备sys_log日志表（mysql）

DROP TABLE IF EXISTS `sys_log`;
CREATE TABLE `sys_log` (
  `id` char(20) NOT NULL COMMENT '编号',
  `operator` varchar(255) DEFAULT NULL COMMENT '操作人',
  `operation_time` datetime DEFAULT NULL COMMENT '操作时间',
  `title` varchar(255) DEFAULT NULL COMMENT '编号',
  `method` varchar(255) DEFAULT NULL COMMENT '方法',
  `type` varchar(255) DEFAULT NULL COMMENT '请求方式',
  `params` varchar(255) DEFAULT NULL COMMENT '参数',
  `state` bit(1) DEFAULT NULL COMMENT '状态',
  `action` varchar(255) DEFAULT NULL COMMENT '操作',
  `request_ip` varchar(255) DEFAULT NULL COMMENT '请求ip',
  `address` varchar(255) DEFAULT NULL COMMENT 'ip来源',
  `browser` varchar(255) DEFAULT NULL COMMENT '浏览器',
  `time` bigint(10) DEFAULT NULL COMMENT '请求耗时',
  `error` text COMMENT '异常信息',
  `system` varchar(255) DEFAULT NULL COMMENT '操作系统',
  PRIMARY KEY (`id`) USING BTREE
