这是由于没有启动Dubbo的dubbo-monitor监控项目致使的。咱们能够置之不理，若是看着不爽的话，就把dubbo-monitor工程下载下来，而后启动起来便可。（附件中是我下载的，能够按照下述方法安装便可http://pan.baidu.com/s/1bnLwBRT）浏览器
若是是window ，进入\dubbo-monitor-simple-2.5.3\conf 修改里面的dubbo.properties 文件：app
dubbo.registry.address = xxx ide
更改成本身得dubbo-minitor注册路径便可spa
而后启动 start.bat,启动完成后，在浏览器上能够访问http://localhost:8081/ code
