dubbo个人感觉很牛逼的功能就是支持多协议了,可以把服务暴露成各种协议 如: http,webservice,hessian,rmi...等

这里简单介绍下同时发布成dubbo和webservice两种协议

代码在 dubbo(二)注册中心zookeeper 的基础上进行改造

在tm-dubbo-provider 和 tm-dubbo-consumer的pom.xml 中增加ws的依赖

<dependency>
	<groupId>org.apache.cxf</groupId>
	<artifactId>cxf-rt-frontend-simple</artifactId>
	<version>2.6.1</version>
</dependency>
<dependency>
	<groupId>org.apache.cxf</groupId>
	<artifactId>cxf-rt-transports-http</artifactId>
	<version>2.6.1</version>
</dependency>
<dependency>
	<groupId>org.mortbay.jetty</groupId>
	<artifactId>jetty</artifactId>
	<version>6.1.26</version>
	<exclusions>
		<exclusion>
			<groupId>org.mortbay.jetty</groupId>
			<artifactId>servlet-api</artifactId>
		</exclusion>
	</exclusions>
</dependency>

在 tm-dubbo-api 中增加接口

public interface SystemApi {
	String uuid(Integer id);
}

在 tm-dubbo-provider中

增加实现SystemApiService.java

public class SystemApiService implements SystemApi {

	@Override
	public String uuid(Integer id) {
		return USERS.get(id.hashCode() % USERS.size()) + ":" + UUID.randomUUID();
	}

	private static final List<String> USERS = new ArrayList<>();
	static {
		USERS.add("唐僧");
		USERS.add("八戒");
		USERS.add("悟空");
		USERS.add("沙僧");
	}
	
}

修改 spring-dubbo-provider.xml

<dubbo:application name="tm-dubbo-provider"/>

<dubbo:protocol name="webservice" port="8082"/>
<dubbo:protocol name="dubbo" port="20880" />

<dubbo:registry address="zookeeper://192.168.2.167:2181"/>

<dubbo:service interface="cn.majingjing.tm.UserApi" ref="UserApi"  protocol="webservice"/>
<dubbo:service interface="cn.majingjing.tm.SystemApi" ref="SystemApi"  protocol="dubbo"/>

<bean id="UserApi" class="cn.majingjing.tm.UserApiService" />
<bean id="SystemApi" class="cn.majingjing.tm.SystemApiService" />

在 tm-dubbo-consumer中

增加controller的调用

@RequestMapping("/dubbo/t2")
public Object t2(Integer id) {
	String name = systemApi.uuid(id);
	System.out.println(name);
	return name;
}

修改 spring-dubbo-consumer.xml

<dubbo:application name="tm-dubbo-consumer" />

<dubbo:registry address="zookeeper://192.168.2.167:2181" />

<dubbo:protocol name="webservice" port="8082" />
<dubbo:protocol name="dubbo" port="20880" />

<dubbo:reference id="userApi" interface="cn.majingjing.tm.UserApi" protocol="webservice" />
<dubbo:reference id="systemApi" interface="cn.majingjing.tm.SystemApi" protocol="dubbo" />

启动服务,打开浏览器访问 dubbo的管理控制台 http://localhost:18080 可以看到有两个服务提供出来了

可以看到UserApi发布成了webservice服务,SystemApi发布成了dubbo服务

访问浏览器查看服务是否成功

http://localhost:8080/tm-dubbo-consumer/dubbo/t1?id=1

http://localhost:8080/tm-dubbo-consumer/dubbo/t2?id=1
