关于dubbo服务启动后自动停止的解决办法

 

 

周末两天在家准备把dubbo相关知识系统过一下，顺便写个demo以备以后不时之需，什么时候写demo都是先在网上找一下有没有别人总结好的，有的话直接拿过来修改修改就ok了。通过《一个简单的dubbo服务》

这篇文章在github上找到了对应的demo示例，直接clone下来对照着文章看了一遍没问题尝试着启动dubbo服务。

 

启动provider：

C:Program FilesJavajdk1.8.0_101injava"

......

[27/08/17 10:48:39:039 CST] main  INFO zookeeper.ZookeeperRegistry:  [DUBBO] Notify urls for subscribe url provider://192.168.1.101:20880/api.PermissionService?anyhost=true&application=demotest-provider&category=configurators&check=false&dubbo=2.4.10&interface=api.PermissionService&methods=getPermissions&organization=dubbox&owner=programmer&pid=7436&side=provider&timestamp=1503802117211, urls: [empty://192.168.1.101:20880/api.PermissionService?anyhost=true&application=demotest-provider&category=configurators&check=false&dubbo=2.4.10&interface=api.PermissionService&methods=getPermissions&organization=dubbox&owner=programmer&pid=7436&side=provider&timestamp=1503802117211], dubbo version: 2.4.10, current host: 127.0.0.1

[27/08/17 10:48:39:039 CST] main  INFO container.Main:  [DUBBO] Dubbo SpringContainer started!, dubbo version: 2.4.10, current host: 127.0.0.1

[2017-08-27 10:48:39] Dubbo service server started!

 

正常启动，没问题！

 

启动consumer：

"C:Program FilesJavajdk1.8.0_101injava" 

......

......

 

问题来了，在消费完provider端服务后自动关停消费者端服务！

折腾了一番，替换dubbo版本号(2.8.4)后，正常运行了！

1、为什么要替换原文示例项目pom.xml指定的dubbo版本号？

其实不止是替换掉了dubbo版本号，示例项目中pom.xml中的dubbo框架依赖本身框架里的spring，里面的spring依赖关系混乱，在替换的时候同时把dubbo的版本号由2.8.4替换成了2.4.10，正是由于低版本的框架bug导致问题的产生，改回2.8.4版本后完美运行！完整pom.xml：
