一.编写消费者

1.新建MavenWeb项目,编写接口和实现类

2.在web.xml中

<?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_3_0.xsd" version="3.0">
    
    
      <display-name>Archetype Created Web Application</display-name>
    
      
      <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        
        
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
      </servlet>
      
      <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        
        <url-pattern>/</url-pattern>
      </servlet-mapping>
      
    
    
    
      
      
      <context-param>
        <param-name>contextConfigLocation</param-name>
        
        <param-value>classpath:dubbo.xml</param-value>
      </context-param>
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
    
      
      <filter>
        <filter-name>encoding</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>
      </filter>
      <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
    
    </web-app>

3.在resource中新建spring配置文件applicationContext.xml和dubbo.xml  
applicationContext.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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
    
    
        
        <mvc:annotation-driven></mvc:annotation-driven>
        
        <context:component-scan base-package="com.tiglle.*"></context:component-scan>
    
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/WEB-INF/page/"></property>
            
            <property name="suffix" value=".jsp"></property>
        </bean>
    
    </beans>

dubbo.xml:

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    
    
    
        
    
        
        <dubbo:application name="tiglle-dubbo-web"/>
    
    
        
        <dubbo:registry id="zk" address="tianxiaolin.cn:2181" protocol="zookeeper"/>
    
        
        <dubbo:consumer registry="zk"/>
    
        
        <dubbo:reference id="sayName" interface="com.tiglle.service.SayName"/>
        
        
        
    
    </beans>

4.新建接口SayName和控制器MainController  
SayName

package com.tiglle.service;
    
    /** * Created by Administrator on 2017/3/26 0026. */
    public interface SayName { 
    
        public String sayName(String name);
    
    }

MainController

package com.tiglle.controller;
    
    import com.tiglle.service.SayName;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import java.util.Map;
    
    /** * Created by Administrator on 2017/3/26 0026. */
    @Controller
    public class MainController { 
    
        @Autowired
        private SayName sayName;
    
    
        @RequestMapping("/main")
        public String main(Map<String, Object> map){
            String name =  sayName.sayName("xiaoming");
            map.put("name",name);
            return "main";
        }
    }
    5.在WEB-INF/下新建page/main.jsp
    main.jsp:

<%@ page contentType=”text/html;charset=UTF-8” language=”java” %>  
<.html>  
<.head>  
<.title>main<./title>  
<./head>  
<.body>  
名字:$\{name\}  
<./body>  
<./html>  
6.启动tomcat,访问连接:[http://localhost:8080/web/main][http_localhost_8080_web_main]  
名字:我的名字是:xiaoming

[http_localhost_8080_web_main]: http://localhost:8080/web/main
