上面的錯誤 百度查了不少端口已經開放 也不是防火牆問題，也有說是序列化問題 查了下基類就是可序列化的也排除了
1，需要進行實例化的類沒有進行實例化，具體沒有實例化的類會在錯誤信息中顯示，在錯誤信息中搜索“Serializable”
即可找到將其實現序列化可消除錯誤。
2，是在使用Dubbo提供服務是在主機上啟動了虛擬機的網絡，在Windows中具體可以，在運行中輸入“CMD”在CMD窗口中輸入"ifconfig"命令查看，
這些問題都排查之后 需要注意
檢查這個沒問題后 繼續查。
如果是java報錯沒有提供者 就需要思考誰是提供者，誰是消費者。我一直以為是zookeeper來 其實zookeeper是個注冊中心他是與消費者提供者接觸的。
正確應該是edu-service-user工程下 src/test/java dubbo.test.DubboProvider.java 先run as啟動 提供者這個工程已經啟動了
下面開始 edu-web-boss maven build 啟動 訪問localhsot
http://localhost:8080/edu-web-boss
success！
