Spring Boot整合Dubbo框架demo

Dubbo框架原理见之前的博文：http://www.cnblogs.com/umgsai/p/5836925.html

首先启动zookeeper

Server端

Pom配置如下

发布服务配置

<?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">    <!-- 提供方应用信息，用于计算依赖关系 -->    <dubbo:application name="demo-provider" />    <!-- 使用zookeeper注册中心暴露服务地址 -->    <dubbo:registry protocol="zookeeper" address="localhost:2181" />    <!-- 用dubbo协议在20880端口暴露服务 -->    <dubbo:protocol name="dubbo" port="20880" />    <!-- 用户服务接口 -->    <dubbo:service interface="com.springboot.demo.UserService" ref="userService" />    <bean id="userService" class="com.springboot.demo.UserServiceImpl"/></beans>

测试接口

public interface UserService {    public String getUserName();}

接口实现

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

Spring Boot启动类

@ImportResource("classpath:config/appcontext-*.xml")@Controller//@EnableAutoConfiguration@SpringBootApplicationpublic class SampleController {    @RequestMapping("/home")    @ResponseBody    String home() {        return "Hello world";    }    public static void main(String[] args) throws Exception {        SpringApplication.run(SampleController.class, args);    }}

启动Spring Boot即可在zookeeper上注册服务端

Client端

Pom配置如下

服务配置

<?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">    <!--消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->    <dubbo:application name="demo-consumer"/>    <!--zookeeper注册中心 -->    <dubbo:registry  protocol="zookeeper" address="localhost:2181" />    <!--使用multicast广播注册中心暴露的服务地址 -->    <!--<dubbo:registryaddress="multicast://10.57.41.19:1234" /> -->    <!-- 生成远程服务代理，可以和本地bean一样使用demoService-->    <dubbo:reference id="userService" interface="com.springboot.demo.UserService" /></beans>

接口从API包中引入，通过以上配置，Dubbo即可实例化配置的接口

调用端代码如下

@ImportResource("classpath:appcontext-*.xml")@Controller//@EnableAutoConfiguration@SpringBootApplicationpublic 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);    }    //修改启动端口    @Override    public void customize(ConfigurableEmbeddedServletContainer container) {        container.setPort(8081);    }}

通过访问http://localhost:8081/home即可调用服务端的方法。
