Dubbo框架原理見以前的博文：http://www.cnblogs.com/umgsai/p/5836925.htmlhtml

首先啓動zookeeperjava

Server端

發佈服務配置spring

<?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">

    <!-- 提供方應用信息，用於計算依賴關係 -->
    <dubbo:application name="demo-provider" />

    <!-- 使用zookeeper註冊中心暴露服務地址 -->
    <dubbo:registry protocol="zookeeper" address="localhost:2181" />

    <!-- 用dubbo協議在20880端口暴露服務 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 用戶服務接口 -->
    <dubbo:service interface="com.springboot.demo.UserService" ref="userService" />

    <bean id="userService" class="com.springboot.demo.UserServiceImpl"/>

</beans>

測試接口apache

public interface UserService {
    public String getUserName();
}

接口實現springboot

public class UserServiceImpl implements UserService {
    public String getUserName() {
        System.out.println("Being invoked");
        return "test user";
    }
}

Spring Boot啓動類app

@ImportResource("classpath:config/appcontext-*.xml")
@Controller
//@EnableAutoConfiguration
@SpringBootApplication
public class SampleController {

    @RequestMapping("/home")
    @ResponseBody
    String home() {
        return "Hello world";
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SampleController.class, args);
    }
}

啓動Spring Boot便可在zookeeper上註冊服務端框架

Client端

服務配置ide

<?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">

    <!--消費方應用名，用於計算依賴關係，不是匹配條件，不要與提供方同樣 -->
    <dubbo:application name="demo-consumer"/>
    <!--zookeeper註冊中心 -->
    <dubbo:registry  protocol="zookeeper" address="localhost:2181" />
    <!--使用multicast廣播註冊中心暴露的服務地址 -->
    <!--<dubbo:registryaddress="multicast://10.57.41.19:1234" /> -->
    <!-- 生成遠程服務代理，能夠和本地bean同樣使用demoService-->
    <dubbo:reference id="userService" interface="com.springboot.demo.UserService" />

</beans>

接口從API包中引入，經過以上配置，Dubbo便可實例化配置的接口

調用端代碼以下

@ImportResource("classpath:appcontext-*.xml")
@Controller
//@EnableAutoConfiguration
@SpringBootApplication
public class MainController extends SpringBootServletInitializer implements EmbeddedServletContainerCustomizer {

    @Autowired
    private UserService userService;

    @RequestMapping("/home")
    @ResponseBody
    public String home() {
        return userService.getUserName();
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MainController.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MainController.class);
    }

    //修改啓動端口
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        container.setPort(8081);
    }
}

經過訪問http://localhost:8081/home便可調用服務端的方法。
