Dubbo+zookeeper入门实例

服务方

服务方的目录结构

依赖
spring的一些依赖，内置tomcat+dubbo+zookeeper的依赖

com.alibaba dubbo 2.5.10 org.apache.zookeeper zookeeper 3.4.12 com.github.sgroschupf zkclient 0.1 org.apache.maven.plugins maven-compiler-plugin 3.7.0 1.8 1.8 UTF8 org.apache.tomcat.maven tomcat7-maven-plugin 8802 /

配置 web.xml
因为是war包所以需要再webapp下建立WEB-INF/web.xml

contextConfigLocation classpath:applicationContext.xml org.springframework.web.context.ContextLoaderListener

applicationContext.xml

java文件
service接口和实现类（注解使用阿里提供的@service）

package org.students.server.impl;import org.students.server.StudentServer;import com.alibaba.dubbo.config.annotation.Service;@Service//阿里提供的public class StudentServerImpl implements StudentServer{public String server(String name) {return "server:" +name;}}

消费方

依赖：跟上面服务方一样配置 web.xml

CharacterEncodingfilter org.springframework.web.filter.CharacterEncodingFilter encoding UTF-8 foreEncoding UTF-8 CharacterEncodingfilter/* dispatcherServlet org.springframework.web.servlet.DispatcherServlet contextConfigLocationclasspath:springmvc.xml dispatcherServlet *.action

springmvc.xml
dubbo服务方要配，消费方也要配

<?xml version="1.0" encoding="UTF-8"?>

java类
service的接口 和controller
service的接口：跟服务方的service接口一样，要在controller中远程调用服务端中StudentServer 然后自动装配。

package org.students.server;public interface StudentServer {public String server(String name);//zs}

package org.controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import org.students.server.StudentServer;import com.alibaba.dubbo.config.annotation.Reference;@RestController@RequestMapping("controller")public class StudentController {@Reference//调用远程服务中的StudentServer StudentServer stuServer ; @RequestMapping("rpcSerer")public String rpcSerer() {String result = stuServer.server("zs") ;return result ;//将结果显示在控制台}}

测试

消费方tomcat端口号为8803
访问http://localhost:8803/controller/rpcSerer.action
