1.用maven管理依赖

排除dubbo对spring的依赖

<dependency>  
            <groupId>com.alibaba</groupId>  
            <artifactId>dubbo</artifactId>  
            <version>2.5.3</version>  
            <exclusions>  
                <exclusion>  
                    <groupId>org.springframework</groupId>  
                    <artifactId>spring</artifactId>  
                </exclusion>  
            </exclusions>  
</dependency>

排除zookeeper对slf4j的依赖

<dependency>  
   <groupId>org.apache.zookeeper</groupId>  
   <artifactId>zookeeper</artifactId>  
   <version>3.4.6</version>  
   <exclusions>  
                <exclusion>  
                    <groupId>org.slf4j</groupId>  
                    <artifactId>slf4j-log4j12</artifactId>  
                </exclusion>  
                <exclusion>  
                    <groupId>log4j</groupId>  
                    <artifactId>log4j</artifactId>  
                </exclusion>  
            </exclusions>  
  </dependency>

<dependency>  
   <groupId>com.github.sgroschupf</groupId>  
   <artifactId>zkclient</artifactId>  
   <version>0.1</version>  
  </dependency>

2.新建一个接口方便其他类公用

public interface UserService \{  
 public String getUserInfo(String username);  
\}

3.实现类 注解是spring的非dubbo的

@Service  
public class UserServiceImpl implements UserService\{  
 public String getUserInfo(String username) \{  
  return "hello:"+ username;  
 \}  
\}

4.配置dubbo

@Configuration   
@PropertySource("classpath:dubbo.properties")   
@ImportResource(\{"classpath:dubbo.xml"\})  
public class DubboConfig \{

dubbo.properties如图 dubbo.xml 如图

1.  \#应用名称

1.   *  dubbo.application.name=example\-provider

1.  \#注册中心类型  
2.  dubbo.registry.protocol=zookeeper  
3.  \#注册中心地址  
4.  dubbo.registry.address=127.0.0.1:2181  
5.  \#暴露服务方式  
6.  dubbo.protocol.name=dubbo  
7.  \#暴露服务端口  
8.  dubbo.protocol.port=20880

![Center][]

![Center 1][]

5.启动zookeeper
