百战不败，依不自称常胜，百败不颓，依能奋力前行。——这才是真正的堪称强大！！

开发步骤
完成服务提供方的编写，完成服务消费方的编写

第一步：创建服务提供方的工程
第二步：配置pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.echo.dubboxservice</groupId><artifactId>dubbox-service</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name>dubbox-service</name><properties>     <spring.version>4.2.4.RELEASE</spring.version></properties><dependencies><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jms</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency>   <!-- dubbo相关 --><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.8.4</version>            </dependency><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.6</version></dependency><dependency><groupId>com.github.sgroschupf</groupId><artifactId>zkclient</artifactId><version>0.1</version></dependency><dependency><groupId>javassist</groupId><artifactId>javassist</artifactId><version>3.11.0.GA</version></dependency></dependencies><build>  <plugins><plugin>  <groupId>org.apache.maven.plugins</groupId>  <artifactId>maven-compiler-plugin</artifactId>  <version>2.3.2</version>  <configuration>  <source>1.8</source>  <target>1.8</target>  </configuration>  </plugin><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><port>10080</port></configuration></plugin></plugins>  </build>
</project>

第三步：配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"><display-name>springmvc</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 加载spring容器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener></web-app>

第四步：配置applicationContext-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><dubbo:application name="dubbox-service"/><dubbo:registry address="zookeeper://192.168.25.129:2181"/><dubbo:annotation package="com.echo.service.impl" /></beans>

第五步：编写接口

package com.echo.service;
public interface UserService {public String getName();
}

第六步：编写实现

package com.echo.service.impl;import com.alibaba.dubbo.config.annotation.Service;
import com.echo.service.UserService;
@Service
public class UserServiceImpl implements UserService{@Overridepublic String getName() {return "echo";}}

注意：要在开发工具上配置一个离线约束http://code.alibabatech.com/schema/dubbo/dubbo.xsd

第七步：编写服务消费方，创建工程
第八步：配置web.xml,注意：两个工程的pom文件都一样，只是服务端口不能相同

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"version="2.5">  <!-- 解决post乱码 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param><init-param>  <param-name>forceEncoding</param-name>  <param-value>true</param-value>  </init-param>  </filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>   <servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 指定加载的配置文件 ，通过参数contextConfigLocation加载--><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping>
</web-app>

第九步：编写控制类

package com.echo.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import com.alibaba.dubbo.config.annotation.Reference;
import com.echo.service.UserService;@Controller
@RequestMapping("/user")
public class UserController {@Reference//代表远程引用private UserService userServie;@RequestMapping("/showName")@ResponseBodypublic String showName(){return userServie.getName();}
}

第十步：将服务提供方复制到服务消费方
第十一步：保证zookeeper是启动的
第十二步：在maven仓库配置dubbox的支持jar包，注意：要首先保证系统环境变量已经配置了maven
首先将dubbo-2.8.4放在D盘根目录下，然后执行这条命令：mvn install:install-file -Dfile=d:\dubbo-2.8.4.jar -DgroupId=com.alibaba -DartifactId=dubbo -Dversion=2.8.4 -Dpackaging=jar
第三步：先启动服务提供方，再启动服务消费方，访问服务消费方，看是否是服务提供方返回的信息，如果是demo运行成功（访问路径：http://localhost:10081/user/showName.do）
