Dubbo+Zookeeper+Spring MVC+JDK8整合应用
软件版本说明：dubbo-admin-2.5.4.war，zookeeper-3.4.9.tar.gz，dubbo-2.8.4，jdk8，apache-tomcat-7.0.68
一. zookeeper安装
# 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.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
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•dataDir：顾名思义就是 Zookeeper保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
•dataLogDir：顾名思义就是Zookeeper 保存日志文件的目录
•clientPort：这个端口就是客户端连接Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求
接着启动zookeeper注册中心服务。
linux下执行命令：bin/zkServer.sh start ；windows下直接双击zkServer.cmd就可以启动服务了。
zookeeper客户端工具推荐ZooInspector，下载地址：https://issues.apache.org/jira/secure/attachment/12436620/ZooInspector.zip，解压缩后双击ZooInspector\build\zookeeper-dev-ZooInspector.jar，连接zookeeper服务，就可以看到已经向zookeeper注册的服务
二. 接口服务
新建一个单独的服务接口工程，定义一个服务接口类DemoService，服务提供方和消费方公用。
package com.dubbo.service;
public interface DemoService {
public String sayHello(String name);
}
三. 提供者服务
新建一个服务提供工程，定义一个DemoService接口的实现类DemoServiceImpl，即远程请求的服务类。
package com.dubbo.api.service;
import com.dubbo.service.DemoService;
public class DemoServiceImpl implements DemoService {
public String sayHello(String name) {
return "Hello " + name;
}
}
spring mvc配置暴露服务
application/json;charset=UTF-8
四. 消费者服务
新建一个消费者服务工程，新建一个测试类SayHelloController
package com.dubbo.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.dubbo.service.DemoService;
@Controller
public class SayHelloController {
@Autowired
private DemoService demoService;
@RequestMapping(value = "/test")
@ResponseBody
public String sayHello(String name){
StringBuffer sb = new StringBuffer("Dubbo: ");
sb.append(demoService.sayHello(name));
return sb.toString();
}
}
启动服务，在浏览器中输入请求的url:http://localhost:8080/springmvc-dubbo-test/test?name=666666
测试结果：666666
五. Dubbo的管理页
1. dubbo-admin-2.5.4下载地址：http://download.csdn.net/detail/dfdsggdgg/9724631
2. 解压dubbo-admin-2.5.4.war，将dubbo-admin-2.5.4下的文件替换到tomcat/webapps/ROOT文件夹下（即替换tomcat的启动主页）
3. 编辑webapps\ROOT\WEB-INF下的dubbo.properties文件
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=123456dubbo.admin.root.password就是登陆的密码
4. dubbo管理登录：http://127.0.0.1:28080/，这里设置tomcat的端口号为28080
dubbo中的服务
提供者
消费者
