1、运行dubbo的三种方式
2、与springboot整合
2.1、服务提供者provider
2.2、服务消费者consumer
3、SpringBoot与dubbo整合的三种方式

1、运行dubbo的三种方式    <--返回目录

1）使用tomcat启动dubbo服务（打成war包）
2）使用main主线程启动dubbo服务

public class MainApp {
    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext ioc = new ClassPathXmlApplicationContext("provider.xml");
        ioc.start();

        System.in.read();
    }
}


3）使用dubbo内置main打包jar启动

2、与springboot整合    <--返回目录

　　参考上一篇博客：搭建注册中心和管理后台

　　启动zookeeper；启动dubbo-admin（通过localhost:7001访问）

2.1、服务提供者provider    <--返回目录

　　启动provider和consumer。通过dubbo-admin查看启动情况。

　　访问 localhost:8081/initOrder

dubbo记录2（运行dubbo的三种方式、与springboot整合、SpringBoot与dubbo整合的三种方式）

3、SpringBoot与dubbo整合的三种方式    <--返回目录

　　1）、导入dubbo-starter，在application.properties配置属性，使用@Service【暴露服务】使用@Reference【引用服务】
　　2）、保留dubbo xml配置文件;
　　　　导入dubbo-starter，使用@ImportResource导入dubbo的配置文件即可
　　3）、使用注解API的方式：
　　　　将每一个组件(指dubbo:xxx这种标签)手动创建到容器中,让dubbo来扫描其他的组件

　　配置参考 MyDubboConfig
