【JEECG Dubbo专题】jeecg-p3集成dubbo文档
一、项目介绍p3dubbo-service接口项目
p3dubbo-service-impl接口实现项目
jeecg-p3-webdubbo提供服务项目（服务端）
p3dubbo-consumerdubbo消费项目（客户端）
二、项目分解说明1 . p3dubbo-service说明：该项目为简单的maven构建项目，无任何依赖引用，只作接口定义 http://img.blog.csdn.net/20160811161240362?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center接口定义如下：http://img.blog.csdn.net/20160811162008436?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center pom文件说明http://img.blog.csdn.net/20160811155520183?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center2. p3dubbo-service说明：该项目为接口实现项目，进行业务逻辑编写 http://img.blog.csdn.net/20160811155700793?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
接口实现如下：
@Service("demoService")
public class DemoServiceImpl implements DemoServiceI {
public String sayHello(String name) {
System.out.println(" -- jeecg-p3-dubbo---say: "+name);
return name + "";
}
}
pom如下：（引入jeecg-p3父POM,增加dubbo依赖支持）

3..jeecg-p3-web (启动项目)说明：该项目为jeecg-p3启动项目，作为服务提供项目，需要引入p3dubbo-service-impl项目1）引入spring dubbo配置 http://img.blog.csdn.net/20160811161404347?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center 2）pom引入接口实现项目 http://img.blog.csdn.net/20160811161451006?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center 启动项目jeecg-p3-web，提供服务（前台先按照zookeeper）4. p3dubbo-consumer(消费项目) http://img.blog.csdn.net/20160811160205514?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center测试类：
public class DubboConsumer {
public static void main(String[] args) throws Exception {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationContext.xml" });
context.start();
DemoServiceI demoService = (DemoServiceI) context.getBean("demoService");
String hello = demoService.sayHello("1998");
System.out.println(hello);
}
}
