Java Application、Web应用

Maven:

<dependency>  
         <groupId>com.alibaba</groupId>  
         <artifactId>dubbo</artifactId>  
         <version>2.5.5</version>  
    </dependency>

**四、配置消费者XML**

![Center 1][]

**五、my-provider工程中src/test/java 是测试消费者**

![Center 2][]

**（5.1）spring-dubbo-consumer.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:dubbo="http://code.alibabatech.com/schema/dubbo"
    	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="my-consumer" />
    
    	
    	<dubbo:registry id="zk1" address="127.0.0.1:2181"
    		protocol="zookeeper" />
    	
    	
    	<dubbo:consumer registry="zk1"/>
    	
    	
    	<dubbo:reference interface="com.hlx.service.UserService" id="userService"/>
    
    
    
    </beans>

**(5.2)spring-context.xml**

**(5.3) 测试类**

package com.hlx.test;
    
    import javax.annotation.Resource;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import com.hlx.service.UserService;
    
    //导入Junit4
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations={"spring-dubbo-consumer.xml","spring-context.xml"})   //导入spring-test.jar
    public class BaseTest {
    
    	@Resource
    	private UserService userService;
    	
    	@Test
    	public void my(){
