Dubbox服务demo

一、安装虚拟机，安装所需要的jdk、zookeeper并启动zookeeper,虚拟机的ip+zookeeper默认端口号2181

二、编写Service服务方

　　1.创建Maven项目 

2.编写接口　　　

public interface UserService {

public String getUserName();
}

接口实现类

import com.alibaba.dubbo.config.annotation.Service;
import com.lf.service.UserService;
@Service
public class UserServiceImpl implements UserService {

@Override
public String getUserName() {
// TODO Auto-generated method stub
return "zookeeperServicedemo";
}

}

3. 创建配置文件applicationContext-service.xml

　　加入如下配置：

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">

 

4.在WEB-INF下加入web.xml

　　添加如下配置：　　

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_2_5.xsd"
version="2.5">



contextConfigLocation
classpath:applicationContext*.xml


org.springframework.web.context.ContextLoaderListener

 

5.pom.xml添加依赖

　

4.2.4.RELEASE

6.启动服务方服务

　　配置 clean tomcat7:run 启动服务

三、编写服务消费方

1.创建maven消费方

2.把服务方的接口复制到消费方

public interface UserService {

public String getUserName();
}

编写控制层代码

@Controller
@RequestMapping("/user")
public class UserController {

@Reference//引用接口
private UserService userService;

@RequestMapping("/getName")
@ResponseBody
public String showName(){
return userService.getUserName();
}
}

3加入mvc配置springmvc.xml

　　　添加如下配置：　　

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/context http://www.springframework.org/schema/context/spring-context.xsd">

4.在WEB-INF下加入web.xml

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_2_5.xsd"
version="2.5">


CharacterEncodingFilter

5.添加pom.xml的依赖

6.启动消费方

7.访问服务

http://localhost:8082/user/getName.do

页面响应：zookeeperServicedemo

四、虚拟机中安装Tomcat，并在Tomcat下webapps中添加dubbox源码编译打包后的dubbox.admin.war

启动Tomcat，访问http://192.168.25.128:8080/dubbo-admin

输入账号、密码： root\root
