alibaba dubbo基本上已經停止更新了，新用戶請使用當當維護的 dubbox， dubbox 在 dubbo 的基礎上添加了對 restfull 的支持，升級了 spring。

webx的依賴改為3.1.6版；
<dependency> <groupId>com.alibaba.citrus</groupId> <artifactId>citrus-webx-all</artifactId> <version>3.1.6</version> </dependency>添加velocity的依賴
<dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity</artifactId> <version>1.7</version> </dependency>對依賴項dubbo添加exclusion，避免引入舊spring
<dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>${project.parent.version}</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency>webx已有spring 3以上的依賴，因此注釋掉dubbo-admin里面的spring依賴

啟動&測試
啟動 server 端
bin/zkServer.sh start啟動客戶端，嘗試創建、查詢節點
bin/zkCli.sh -server localhost:2181 [zk: localhost:2181(CONNECTED) 3] create /test 1111 Created /test [zk: localhost:2181(CONNECTED) 4] get /test 1111 cZxid = 0x2 ctime = Thu Sep 01 08:59:24 CST 2016 mZxid = 0x2 mtime = Thu Sep 01 08:59:24 CST 2016 pZxid = 0x2 cversion = 0 dataVersion = 0 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 4 numChildren = 0
安裝dubbo-admin
-
安裝tomcat
yum install tomcat6
-
部署 dubbo-admin 代碼
mkdir /var/lib/tomcat6/webapps/ROOT/ unzip dubbo-admin/target/dubbo-admin-2.5.3.war -d /var/lib/tomcat6/webapps/ROOT/確認/var/lib/tomcat6/webapps/ROOT/WEB-INF/dubbo.properties 中ZooKeeper的地址是否正確。本例中，該配置無需修改。 然后就可以啟動tomcat了。
/etc/init.d/tomcat6 restart可以通過瀏覽器訪問 dubbo-admin。
啟動demon
provider
cd /usr/local/src/dubbo/dubbo-demo/dubbo-demo-provider/target/
tar -zxf dubbo-demo-provider-2.5.3-assembly.tar.gz
cd dubbo-demo-provider-2.5.3
修改 conf/dubbo.properties
#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper://127.0.0.1:2181
啟動provider
bin/start.sh
consumer
cd /usr/local/src/dubbo/dubbo-demo/dubbo-demo-consumer/target/
tar -zxf dubbo-demo-consumer-2.5.3-assembly.tar.gz
cd dubbo-demo-consumer-2.5.3
修改 conf/dubbo.properties
#dubbo.registry.address=multicast://224.5.6.7:1234
dubbo.registry.address=zookeeper://127.0.0.1:2181
啟動consumer
bin/start.sh
確認
consumer log
在consumer的日志中可以看到provider的正常回應。
