创建工程qianjibian-customer

创建步骤参考服务器提供者（qianjibian-provider）

添加pom文件

注意下方端口为8082，要不同与提供者端口，目前运行在一台机器上，区别端口

添加web.xml

 <!-- 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:applicationContext-web.xml</param-value>
  	</init-param>
  </servlet>  
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
</web-app>

添加UserController

package com.unistec.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.dubbo.config.annotation.Reference;
import com.unistec.service.UserService;

@RestController
@RequestMapping("/user")
public class UserController {
	
	@Reference
	private UserService userService;
	
	/**
	 * 获取json
	 * @return
	 */
	@RequestMapping("/getName")
	public String getName(){
		return userService.getName();
	}

}

添加UserService（此处service和提供者中的service一样，在实际开发中，单独提出来一个接口工程即可，jar方式）

public interface UserService {
	
	public String getName();

}

注意controller代码，service注入，不是@Autowired，？？？因为现在是通过注册中心进行查找UserService服务，不是调用本地服务，所以要使用@Reference

添加配置文件applicationContext-web.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.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>
	<!-- 引用dubbo 服务 -->
	<dubbo:application name="qianjibian-customer" />
	<dubbo:registry address="zookeeper://192.168.25.129:2181"/>
     <dubbo:annotation package="com.unistec.controller" />
</beans>

注意：上面有个字符串转换配置，另外服务提供者接口要和服务消费者service路径相同，否则会报找不到服务提供者

另外报5000错误，说明没连接上zookper，检查zooker的ip

运行：tomcat7:run
