dubbox 入門Demo
Ⅰ.準備工做
- 準備lnux安裝包
-
zookeeper安裝包java
-
安裝zookeepergit
- tar -zxvf zookeeper-3.4.10
- 配置zk的環境變量
-
啓動單機版zookeepergithub
* zkServer.sh start * 查看zk的狀態 zkServer.sh status
Ⅱ.編寫服務提供方
建立Maven項目web
- 建立web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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">
<!-- 加載spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
導入maven依賴spring

- 編寫接口類
package cn.itcast.dubbox.service;
public interface UserService {
public String getName();
}
- 編寫實現類
package cn.itcast.dubbox.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import cn.itcast.dubbox.service.UserService;
//dubbo的service註解 用於向zookeeper註冊服務
@Service
public class UserServiceImpl implements UserService {
public String getName() {
return "itcast";
}
}
- 編寫spring配置文件
<?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">
//項目名，填寫本身的項目名 個人項目名稱叫作 dubbox-service
<dubbo:application name="dubbox-service" />
//這裏填寫zk的IP以及對應的端口號
<dubbo:registry address="zookeeper://192.168.133.121:2181" />
//dubbox 的包掃描
<dubbo:annotation package="cn.itcast.dubbox.service" />
</beans>
Ⅲ.編寫服務消費方
- 建立maven項目
- 建立web.xml文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<port>8082</port>
<!-- 請求路徑 -->
<path>/</path>
</configuration>
</plugin>
</plugins>
</build>
</project>
- 複製上面的接口
- 編寫controller
package cn.itcast.dubbox.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.alibaba.dubbo.config.annotation.Reference;
import cn.itcast.dubbox.service.UserService;
@RestController
public class indexController {
@Reference
UserService userService;
@RequestMapping("/getName")
public String getName(){
return userService.getName();
}
}
- 編寫springmvc.xml文件
<?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: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 服務 -->
<dubbo:application name="dubbox-web" />
<dubbo:registry address="zookeeper://192.168.133.121:2181" />
<dubbo:annotation package="cn.itcast.dubbox.controller" />
</beans>
