前言
上一章Spring boot2.0 实现日志集成的方法(2)主要讲解了将日志信息根据类别输出到不同的文件中,实际开发中我们需要通过日志来监控用户的操作行为、请求的耗时情况,针对耗时久的请求进行性能分析,提升系统性能。
具体实现
采用的Spring Aop切面技术来实现控用户的操作行为、请求的耗时情况。

{ "className" : "com.test.controller.UserController" , "costTime" : 19 , "createDate" : "2022/03/11 15:20:30" , "createUser" : "xx" , "ip" : "172.18.188.111" , "methodName" : "getUserByName" , "param" : " zhangsan" , "uri" : "/user/getUserByName" , "model" : "用户管理" , "func" : "查询用户信息" , "desc" : "根据用户名称" , "version" : 0 } |
对于一些敏感的信息需要进行加密处理。针对异常的请求进行分析和性能优化。
总结
上述日志信息虽然记录的比较详细,但是缺少了请求的来源,尤其是跨服务之间的调用,则无法进行追踪。链路追踪可以采用Spring Boot +logbck+MDC来实现。
