dubbo學習
1、下載zookeeperhtml
使用dubbo須要先下載zookeeper，下載地址：http://archive.apache.org/dist/zookeeper/，根據本身的須要選擇版本下載。前端
2、配置zookeeperjava
將下載下來的壓縮包解壓，並將conf文件夾下的zoo_sample.cfg重命名爲zoo.cfg，並修改其內容git
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. # 數據存放地址 dataDir=E:/zookeeper-3.4.10/zookeeper-3.4.10/data # 日誌存放地址 dataLogDir=E:/zookeeper-3.4.10/zookeeper-3.4.10/logs # the port at which the clients will connect # 客服端鏈接端口 clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1
3、新建web項目，項目結構爲：github
dubbo-provider的pom文件爲：web

// 初始化Spring
ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-servlet2.xml");
LoginService loginService = (LoginService) ctx.getBean("loginService"); // 獲取遠程服務代理

6、啓動項目
先啓動zookeeper，點擊zookeeper文件夾下bin文件夾下的zkServer.cmd啓動zookeeper。
分別爲provider和consumer，new一個Tomcat，記住consumer的端口改成8006,8081，8010
訪問localhost:8081/dubbo-consumer/login/loginone，能夠看到獲得了provider項目中接口的返回值，遠程調用成功。
