## **一.编写提供者** ##

**方法一:使用dubbo默认的main方法启动**

1.新建Maven项目,编写接口和实现类

2.在pom中加入依赖

<dependencies>
            <dependency>
                
                <groupId>com.alibaba</groupId>
                <artifactId>dubbo</artifactId>
                <version>2.4.10</version>
            </dependency>
            
            <dependency>
                <groupId>com.101tec</groupId>
                <artifactId>zkclient</artifactId>
                <version>0.4</version>
            </dependency>
            
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>3.2.8.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-core</artifactId>
                <version>3.2.8.RELEASE</version>
            </dependency>
        </dependencies>

3.编写接口和实现类SayHellow

4.在resource目录中新建META-INF文件夹，并在MATE-INF下新建spring文件夹，创建配置文件 spring-dubbo.xml(dubbo自带容器运行时读取配置文件的位置)  
详细参考:[http://www.cnblogs.com/linjiqin/p/5859153.html][http_www.cnblogs.com_linjiqin_p_5859153.html]

<?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="tiglle-dubbo-provider" />
    
        
        <dubbo:registry id="zk" address="tianxiaolin.cn:2181" protocol="zookeeper"/>
    
        
        <dubbo:protocol id="mydubbo" name="dubbo" port="20886"/>
    
        
        <dubbo:provider registry="zk" protocol="mydubbo"/>
    
        
        <dubbo:service interface="com.tiglle.service.SayHellow" ref="sayHellow"/>
        
        
        
    
        
        <bean id="sayHellow" class="com.tiglle.service.impl.SayHellowImpl"/>
    
    </beans>
    详细配置:http://blog.csdn.net/huangjin0507/article/details/52234178

5.启动zookeeper

6.启动dubbo自带的main方法：com.alibaba.dubbo.container.Main

7.到zookeeper处查看注册信息，执行zookeeper/bin/zkCli.sh，然后  
ls /  
　　\[dubbo, zookeeper\]  
ls /dubbo  
　　\[com.tiglle.service.SayHellow\]  
ls /dubbo/com.tiglle.service.SayHellow  
　　\[configurators, providers\]  
ls /dubbo/com.tiglle.service.SayHellow/providers  
　　\[dubbo%3A%2F%2F12.12.12.161%3A20886%2Fcom.tiglle.service.SayHellow%3Fanyhost%3Dtrue%26application%3Dtiglle-dubbo-provider%26dubbo%3D2.4.10%26interface%3Dcom.tiglle.service.SayHellow%26methods%3DsayHellow%26pid%3D7080%26side%3Dprovider%26timestamp%3D1490189940409\]

服务注册成功

如果出现注册没有反应，将dubbo:registry 的address改为ip，不使用域名

**方法二：自己编写main方法启动**  
1.新建maven项目，编写接口和实现类  
2.在pom.xml加入dubbo和zookeeper和spring的依赖

<dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
                <version>2.5.6</version>
            </dependency>
    
            
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>dubbo</artifactId>
                <version>2.4.10</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework</groupId>
                        <artifactId>spring</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
    
            
            <dependency>
                <groupId>com.101tec</groupId>
                <artifactId>zkclient</artifactId>
                <version>0.4</version>
            </dependency>
        </dependencies>

3.在resources目录新建spring配置文件dubbo.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="tiglle-dubbo-provider-myself" />
    
        
        <dubbo:registry id="zk" address="tianxiaolin.cn:2181" protocol="zookeeper"/>
    
        
        <dubbo:protocol id="mydubbo" name="dubbo" port="20888"/>
    
        
        <dubbo:provider registry="zk" protocol="mydubbo"/>
    
        
        <dubbo:service interface="com.tiglle.service.SayName" ref="sayName"/>
    
        
        <bean id="sayName" class="com.tiglle.service.impl.SayNameImpl"/>
    
    
    </beans>

4.新建main方法，运行并启动服务，注册到zookeeper

public static void main( String[] args ) throws Exception {
            //加载spring配置文件
            /* 此方法不支持dubbo的配置 BeanFactory context = new XmlBeanFactory(new ClassPathResource("applicationContext.xml")); */
            ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "dubbo.xml" });
            context.start();//启动容器
            System.in.read();// 为保证服务一直开着，利用输入流的阻塞来模拟
            System.out.println( "Hello World!" );
        }

5.到zookeeper查看服务注册信息
