上面的错误 百度查了不少端口已经开放 也不是防火墙问题，也有说是序列化问题 查了下基类就是可序列化的也排除了
1，需要进行实例化的类没有进行实例化，具体没有实例化的类会在错误信息中显示，在错误信息中搜索“Serializable”
即可找到将其实现序列化可消除错误。
2，是在使用Dubbo提供服务是在主机上启动了虚拟机的网络，在Windows中具体可以，在运行中输入“CMD”在CMD窗口中输入"ifconfig"命令查看，
这些问题都排查之后 需要注意
检查这个没问题后 继续查。
如果是java报错没有提供者 就需要思考谁是提供者，谁是消费者。我一直以为是zookeeper来 其实zookeeper是个注册中心他是与消费者提供者接触的。
正确应该是edu-service-user工程下 src/test/java dubbo.test.DubboProvider.java 先run as启动 提供者这个工程已经启动了
下面开始 edu-web-boss maven build 启动 访问localhsot
http://localhost:8080/edu-web-boss
success！
