-
- dubbo.registry.address=zookeeper的集群地址。
- 控制中心是用来做服务治理的,比如控制服务的权重、服务的路由。
- simple监控中心
- 下载dubbo-monitor-simple-2.5.3-assembly.tar.gz包。
- 解压后到解压目录下的dubbo-monitor-simple-2.5.3conf中找到dubbo.properties文件,修改成zookeeper注册中心地址。
-
- 点击bin目录下的start.bat启动,启动成功后,通过http://localhost:8080来访问监控中心。
-
- Monitor也是一个dubbo服务,所以也会有端口和url。
- 监控服务的调用次数、调用关系、响应事件。
- 定义接口以及接口的实现类。
- 配置好Dubbo配置文件后,通过Main方法启动服务端,将服务暴露。

- 第二行的:dubbo://10.0.1.183:20880/com.karat.cn.order_api.IOrderServices 是后面需要用到的服务url地址,使用zookeeper也是让zookeeper来管理这个东西。
