一、安装虚拟机，安装所需要的jdk、zookeeper并启动zookeeper,虚拟机的ip+zookeeper默认端口号2181

二、编写Service服务方

　　1.创建Maven项目 

2.编写接口　　　

public interface UserService {

public String getUserName();
}

接口实现类

import com.alibaba.dubbo.config.annotation.Service;
import com.lf.service.UserService;
@Service
public class UserServiceImpl implements UserService {

@Override
public String getUserName() {
// TODO Auto-generated method stub
return "zookeeperServicedemo";
}

}

3. 创建配置文件applicationContext-service.xml

　　加入如下配置：

<?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.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<!-- dubbox的服务方配置 -->
<dubbo:application name="dubboxdemo-sercice"/>
<dubbo:registry address="zookeeper://192.168.25.128:2181"/>
<dubbo:annotation package="com.lf.service.impl"/>
</beans>

 

4.在WEB-INF下加入web.xml

　　添加如下配置：　　

<?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">

<!-- 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>

 

5.pom.xml添加依赖

　

<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>

<version>${spring.version}</version>
</dependency>

<!-- dubbo相关 -->

</dependency>

</dependencies>
<build>
<plugins>
<plugin>

<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<!-- 指定端口 -->
<port>8081</port>
<!-- 请求路径 -->
<path>/</path>
</configuration>
</plugin>
</plugins>
</build>

6.启动服务方服务

　　配置 clean tomcat7:run 启动服务

三、编写服务消费方

1.创建maven消费方

2.把服务方的接口复制到消费方

public interface UserService {

public String getUserName();
}

编写控制层代码

@Controller
@RequestMapping("/user")
public class UserController {

@Reference//引用接口
private UserService userService;

@RequestMapping("/getName")
@ResponseBody
public String showName(){
return userService.getUserName();
}
}

3加入mvc配置springmvc.xml

　　　添加如下配置：　　

<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.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">


<mvc:annotation-driven >
<mvc:message-converters register-defaults="false">
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8" />
</bean>
</mvc:message-converters>
</mvc:annotation-driven>

<!--dubbox 消费方配置 -->
<dubbo:application name="dubboxdemo-customer"/>
<dubbo:registry address="zookeeper://192.168.25.128:2181"/>
<dubbo:annotation package="com.lf.controller"/>
</beans>

4.在WEB-INF下加入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"
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>

5.添加pom.xml的依赖

6.启动消费方

7.访问服务

http://localhost:8082/user/getName.do

页面响应：zookeeperServicedemo

四、虚拟机中安装Tomcat，并在Tomcat下webapps中添加dubbox源码编译打包后的dubbox.admin.war

启动Tomcat，访问http://192.168.25.128:8080/dubbo-admin

输入账号、密码： root\root
