dubbox入门

dubbox定义：

　　dubbox和dubbo差不多，dubbox由当当网维护，使用http协议和rest编码风格

在maven仓库中添加Doubbox依赖

因为：Maven不支持dubbox直接从中央仓库导入

  1. 我们需要一个dubbox-dubbox.zip包(从github上拿)

　　　　① 博客操作指南：

　　　　② https://blog.csdn.net/try_and_do/article/details/83383861

　　2.解压后需要将文件打成jar包

　　　　① 命令：Jar -cf 文件.jar 文件

　　3.将jar文件导成maven库的依赖

　　　　(将alibaba文件（放入maven库中）替换E:Maven项目管理模型maven_recomalibaba)

　

编码

　　一,导入dubbox依赖（默认从maven库中找dubbox依赖）

1.服务者

　　service接口

@Path("/dosomeService")
public interface DoSomeService {

    @Path("/doSome/{userName}")
    @GET
    @Consumes({ MediaType.APPLICATION_JSON })
    public String doSome(@PathParam("userName") String userName);
}

　　service实现

public class DoSomeServiceImpl implements DoSomeService {
    @Override
    public String doSome(String userName) {
        System.out.println("dubbox 发布的DoSomeService 服务   doSome方法	"+userName);
        return "bubbox";
    }
}

　　aplicationContext-provider.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

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



    <!--声明服务提供方-->
    <dubbo:application name="dubbox-provider"/>
    <!--注册中心地址-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
    <!--dubbo服务端口-->
    <dubbo:protocol name="rest" port="8081"/>


    <!--服务注册-->
    <dubbo:service interface="com.dubbo.service.DoSomeService" ref="doSomeService"/>
    <bean id="doSomeService" class="com.dubbo.service.impl.DoSomeServiceImpl"/>

</beans>

　　　　Apptest

public class AppTest 
{
    public static void main(String[] args) throws IOException {
        //加载配置文件：配置文件中通过SPring将Dubbo服务注册到注册中心当中去
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext-provider.xml");
        System.out.println("dubbox服务已经发布！！！！！");
        //阻塞
        System.in.read();
    }
}

　　

2.消费者

　　　　applicationContext-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"

    <!--声明服务提供方-->
    <dubbo:application name="dubbox-consumer"/>
    <!--注册中心地址-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>

    <!--服务消费-->
    <dubbo:reference interface="com.dubbo.service.doSomeService" id="doSomeService"/>





</beans>

　　　　testControll

public class testControll {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-consumer.xml");
        doSomeService doSomeService = (doSomeService)ctx.getBean("doSomeService");
        doSomeService.doSome("李四");
    }
}
