聊聊PowerJob的DatabaseMonitorAspect

本文主要研究一下PowerJob的DatabaseMonitorAspect

DatabaseMonitorAspect

tech/powerjob/server/persistence/monitor/DatabaseMonitorAspect.java

DatabaseMonitorAspect拦截了remote和local的repository，然后执行wrapperMonitor

wrapperMonitor

wrapperMonitor主要是构建DatabaseEvent，成功时获取effectRows，异常时获取erroMsg，最后计算耗时，执行monitorService.monitor

MonitorService

tech/powerjob/server/monitor/MonitorService.java

MonitorService定义了monitor方法

PowerJobMonitorService

tech/powerjob/server/monitor/PowerJobMonitorService.java

PowerJobMonitorService是实现了MonitorService接口，其monitor方法遍历monitors，挨个执行record方法

Monitor

tech/powerjob/server/monitor/Monitor.java

Monitor接口定义了record方法

LogMonitor

tech/powerjob/server/monitor/monitors/LogMonitor.java

LogMonitor实现了Monitor, ServerInfoAware接口，其record方法通过logger打印event的message
