基于SSM的dubbo的分布式项目框架搭建——提供者，消费者，api结构生成

结构搭建思路：

1）建立dubbo项目的结构
至少两个war包。一个jar包
jar包为公共引用的jar包，主要提供dubbo接口调用的接口和model
其余两个war包，一个是提供者，一个是消费者。

2）建立pom文件，
引入dubbo的jar包
引入dubbo以来的 jar包，因为dubbo有自己依赖的spring，所以maven排除一下。
引入spring 以及springmvc引用的jar包
引入数据源及数据链接的jar包
引入mybatis的jar包
引入日志打印的jar包
3)dubbo 提供者，消费者的配置
4）简单demo实现

基本jar包引入

项目结构就不用说了，这个比较简单。按照自己的喜好，命名建立包，类等就好了。

本人的项目配置

provider.xml配置

<?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="dubbo-provider"/>
    <dubbo:registry address="zookeeper://localhost:2181"/>
    <bean id="demoService" class="dubbo.wk.service.impl.DemoServiceImpl"/>
    <dubbo:service interface="dubbo.wk.service.IDemoService" ref="demoService"/>
</beans>

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"
       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="dubbo-consumer"/>
    <dubbo:registry address="zookeeper://localhost:2181"/>
    <dubbo:reference id="demoService" interface="dubbo.wk.service.IDemoService"/>
    <bean id="demoController" class="dubbo.wk.controller.DemoController">
        <property name="iDemoService" ref="demoService"/>
    </bean>
</beans>

提供者启动

public class provider {
    public static void main(String[] args)throws Exception {
        ClassPathXmlApplicationContext context =
                new ClassPathXmlApplicationContext("classpath:dubbo-provider.xml");
        context.start();
        System.in.read();
    }
}

消费者启动

public class consumer {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context =
                new ClassPathXmlApplicationContext("classpath:dubbo-consumer.xml");
        DemoController controller = (DemoController) context.getBean("demoController");
        controller.sayHelloWorld("武刚鹏");

    }
}

后台代码

public class DemoController {
    @Autowired
    private IDemoService iDemoService;

    public void setiDemoService(IDemoService iDemoService) {
        this.iDemoService = iDemoService;
    }

    //世界你好
    public void sayHelloWorld(String userName) {
        String info = new String("Hello World!");
        DemoRemoteModel model = iDemoService.findDemoModel();
        System.out.println(model.getUserName() + ":" + info);
    }
}

public class DemoServiceImpl implements IDemoService {
    @Override
    public DemoRemoteModel findDemoModel() {
        DemoRemoteModel model = new DemoRemoteModel();
       model.setId(1L);
       model.setUuid(UUID.randomUUID().toString().replaceAll("-",""));
       model.setUserName("武刚鹏");
       return model;
    }
}

遇到问题：

一些jar包无法从中央仓库下载，于是进入官网，手动把jar下载，然后安装到本地仓库。

安装命令：mvn install:install-file -Dfile=jar包的位置 -DgroupId=上面的groupId -DartifactId=上面的artifactId -Dversion=上面的version -Dpackaging=jar

附上本人的安装截图

大家继续期待我的下一篇 ssm框架配置哦
