dubbo学习
1、下载zookeeperhtml
使用dubbo须要先下载zookeeper，下载地址：http://archive.apache.org/dist/zookeeper/，根据本身的须要选择版本下载。前端
2、配置zookeeperjava
将下载下来的压缩包解压，并将conf文件夹下的zoo_sample.cfg重命名为zoo.cfg，并修改其内容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. # 数据存放地址 dataDir=E:/zookeeper-3.4.10/zookeeper-3.4.10/data # 日志存放地址 dataLogDir=E:/zookeeper-3.4.10/zookeeper-3.4.10/logs # the port at which the clients will connect # 客服端链接端口 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项目，项目结构为：github
dubbo-provider的pom文件为：web

private LoginService loginService;
@RequestMapping(value = "/loginone")
@ResponseBody
public String login0(){
return loginService.getStr();

public static void main(String[] args) {
try {
// 初始化Spring
ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-servlet2.xml");
LoginService loginService = (LoginService) ctx.getBean("loginService"); // 获取远程服务代理
System.out.println(loginService.getStr());; // 运行远程方法
} catch (Exception e) {
e.printStackTrace();

}
}
6、启动项目
先启动zookeeper，点击zookeeper文件夹下bin文件夹下的zkServer.cmd启动zookeeper。
分别为provider和consumer，new一个Tomcat，记住consumer的端口改成8006,8081，8010
访问localhost:8081/dubbo-consumer/login/loginone，能够看到获得了provider项目中接口的返回值，远程调用成功。
