现阶段的 Spring Boot 可谓是太火了,为什么呢?因为使用方便、配置简洁、上手快速,那么它是什么?从官网上我们可以看到,它是 Spring 开源组织下的一个子项目,主要简化了 Spring 繁重的配置,而且 Spring Boot 内嵌了各种 Servlet 容器,如:Tomcat、Jetty 等
官方网站:http://projects.spring.io/spring-boot/
GitHub源码:https://github.com/spring-projects/spring-boot
1、独立运行:不需要在用 tomcat 等容器运行。
2、简化配置:不需要在像 Spring mvc 那样配置很多的xml了;
3、自动配置:根据包路径自动配置 bean
4、应用监控:Spring Boot 提供监控服务
后面点击 finish,创建完毕,然后删掉多余包,使得项目结构如下图:
右击项目,新建一个提供者对外提供服务的模块 qbs-facade
然后再按照该模式创建一个 qbs-web 模块(这里就不介绍了)最终的项目结构如下图所示:

SayFacade.java
package com.btd.qbs.facade;
public interface SayFacade {
String say(String context);
}
facade 模块的 xml 文件,它只是对外提供一下接口的,所以不需要其它东西

application.properties 文件

dubbo.application.id=${spring.application.name}
dubbo.application.name=${spring.application.name}
dubbo.protocol.port = 28820
dubbo.protocol.name=${spring.application.name}

SayFacadeImpl.java
package com.btd.qbs.service;
import com.btd.qbs.facade.SayFacade;
import org.apache.dubbo.config.annotation.Service;
@Service
public class SyaFacadeImpl implements SayFacade {
@Override
public String say(String context) {
return "小肥羊对你说:"+context;
}
}
启动文件 Application.java
package com.btd.qbs;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration;
@EnableDubbo
@SpringBootApplication(exclude = MongoAutoConfiguration.class)
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class);
}
}
OK ,到这里来说,我们的提供者就完成了,启动项目,然后我们看看 dubbo-admin
这里要注意,因为我们的 facade 是对外需要映入的,所以我们打个 jar 包
打完包后,我们会得到一个 jar 文件
引入我们打的 jar 包
配置文件:
spring.application.name=qbs-consumer
server.port=11121

public class DbsController {
@Reference
private SayFacade sayFacade;
@GetMapping("/say")
@ResponseBody
public String say(String context) {
return sayFacade.say(context);
}
}
最后调用结果:http://localhost:11121/qbs/say?context=asde3
好了,这是spring boot 集成 dubbo的一整套商业使用的代码事例,按着从上到下的操作,是完全OK的;
