负责服务调用次和调用时间的监控。
扩展接口
org.apache.dubbo.monitor.MonitorFactory
org.apache.dubbo.monitor.Monitor
扩展配置
<!-- 定义监控中心 -->
<dubbo:monitor address="xxx://ip:port" />
已知扩展
org.apache.Dubbo.monitor.support.dubbo.DubboMonitorFactory
扩展示例
- Maven 项目结构:
src |-main |-java |-com |-xxx |-XxxMonitorFactoryjava (实现MonitorFactory接口) |-XxxMonitor.java (实现Monitor接口) |-resources |-META-INF |-dubbo |-org.apache.dubbo.monitor.MonitorFactory (纯文本文件,内容为:xxx=com.xxx.XxxMonitorFactory)
- XxxMonitorFactory.java:
package com.xxx; import org.apache.dubbo.monitor.MonitorFactory; import org.apache.dubbo.monitor.Monitor; import org.apache.dubbo.common.URL; public class XxxMonitorFactory implements MonitorFactory { public Monitor getMonitor(URL url) { return new XxxMonitor(url); } }
- XxxMonitor.java:
package com.xxx; import org.apache.dubbo.monitor.Monitor; public class XxxMonitor implements Monitor { public void count(URL statistics) { // ... } }
- META-INF/dubbo/org.apache.dubbo.monitor.MonitorFactory:
xxx=com.xxx.XxxMonitorFactory
