搭建dubbo服务的方式是参照这篇博客上编辑做的。
http://blog.csdn.net/qduningning/article/details/41445937
其中替换内容为zookeeper中心。此处分享pom.xml:
此结构为下图去掉monitor结构。
搭建zookeeper环境可参考http://www.cnblogs.com/Javame/p/3632708.html 前半段
贴配置:此处,server.x后面得跟ip, 或者在hosts里面有对应。127.0.0.1不行
中间遇到一个极致的问题是:
这个很有可能是启动的角色不对或者是权限不对。改定即可。并且初始启动的时候data目录不能有除了myid之外的其他文件。
正确的结果是这样的:
此处分享一个dubbo特牛的地方:
dubbo server与注册中心为长连接,注册中心挂掉之后会一直报错,直到注册中心重启之后服务竟然又能使用了!

中间遇到一个极致的问题是:

这个很有可能是启动的角色不对或者是权限不对。改定即可。并且初始启动的时候data目录不能有除了myid之外的其他文件。
正确的结果是这样的:
