使用方式：
maven ，配置settings后，引入到项目的pom中：
com.zl.common-core
common-core
1.0.0-SNAPSHOT
若是spring mvc项目，需要配置xml：
webServerLogFilter
com.zl.common.interceptor.WebServerLogFilter
webServerLogFilter
/*
下一步计划：
会实现一版code trace级别的追踪，如：定位代码行的性能（细粒度最大化，方式可选：大屏、arthas、shell）
核心代码实现：
@Order(1)
public class WebServerLogFilter extends OncePerRequestFilter {
/**
* 包装IO，扩展指标项
*/
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {}
}
public class TraceInterceptor implements HandlerInterceptor{
/**
* 验签、验参、指标传递、服务注册、封装MDC资源
*/
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler){}
/**
* 将性能、耗时、异常等指标项，记录到系统日志（db库），并释放MDC资源
*/
@Override
public void afterCompletion(
HttpServletRequest request, HttpServletResponse response, Object handler, Exception exception){}
}
开发约定：
Tomcat access日志格式：
[ %a %{Host}i %t %H %I ] [ %{traceId}o %{token}o %u ] [ %U %s %b %D ] [%m] [%q] [%{User-Agent}i] [%{Referer}i]

上下游参数增强：[request、response]
request：添加header参数
- Referer：请求源
- traceId：追踪链（若request中无，则创建）
response：添加header参数
- traceId：追踪链
仍需留意：rpc、thread、job、主子、异步的处理
可扩展、封装IO，实现更多个性化、业务指标的监控
运行时举例：
Referer: http://localhost:8080/boot-tool/test/listAll
traceId: fd460e91fbac48ca8550f4c640c186b5
SQL方式：（推荐使用）
使用人员：会写SQL即可
日均请求量高时（如100w+），可按天分表
举例：查耗时>1s
select * from sys_log where exec_time>1000 order by exec_time desc limit 10;
举例：查错误码!=200
select * from sys_log where status!=200 order by id desc limit 10;
举例：查返回包大小>10000b
select * from sys_log where sys_log.res_size>10000 order by exec_time desc limit 10;
举例：常用指标汇总统计：最大耗时、最大包、单接口频次等
select path,remark, count(id) req_count,max(exec_time) max_time,min(exec_time) min_time,max(res_size) max_size,min(res_size) min_size from sys_log group by path,remark order by req_count desc;
页面方式：（基础版）
使用人员：全员适用，无技术门槛
可接入h5、小程序，在pc端、移动端显示
大屏方式：（可视化）
使用人员：全员适用，无技术门槛
可接入datav、fineReport等大屏，也可python自行实现图表页
shell方式：（高级版）
使用人员：有shell基础，可简单调参、改条件
已封装工具脚本，可全量执行，看结果即可
举例：直接执行脚本：bash dev_access.sh
$ bash dev_access.sh
input date:
2021-12-28
input max response:
10000
input max time:
1000
start: date = 2021-12-28 , response > 10000 , time > 1000 .
_________________________
end: date = 2021-12-28 , response > 10000 , time > 1000 .
