dubbo之webservice协议使用

普通接口及实现类

public interface WsService {	String sayHello(String msg);}

public class WsServiceImpl implements WsService {	@Override	public String sayHello(String msg) 	{		 return "hello " + msg;	}}

dubbo服务提供者配置

<?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="dubbo-webservice-app-provider"  /><!--     <dubbo:registry protocol="multicast" address="224.5.6.7:1234"/> -->

    <!-- 如果server:servlet,则端口必须与servlet容器端口一致,同时contextpath与servlet应用的上下文相同 -->    <dubbo:protocol name="webservice" port="8080" server="servlet"/>        <dubbo:service interface="com.dubbo.webservice.WsService" ref="wsService" registry="N/A" path="service" />    <bean id="wsService" class="com.dubbo.webservice.WsServiceImpl" /> </beans>

dubbo服务消费者配置

<?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="dubbo-webservice-app-consumer"/>

    <!-- 使用multicast广播注册中心暴露服务地址 -->    <!-- <dubbo:registry address="multicast://224.5.6.7:1234"/> -->

    <!-- 声明需要暴露的服务接口 -->    <dubbo:reference interface="com.dubbo.webservice.WsService" id="wsService" url="webservice://localhost:8080/ProjectBuild/service" registry="N/A"/>

</beans>

web.xml配置

		<servlet>		         <servlet-name>dubbo</servlet-name>		         <servlet-class>com.alibaba.dubbo.remoting.http.servlet.DispatcherServlet</servlet-class>		         <load-on-startup>1</load-on-startup>		</servlet>		<servlet-mapping>		         <servlet-name>dubbo</servlet-name>		         <url-pattern>/*</url-pattern>		</servlet-mapping>

依赖配置文件

    <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>

注意事项

1. 需要指定<dubbo:protocol server="servlet">.
2. jar需要使用2.6.1版本,使用高版本好像有问题,消费者无法访问.
3. 消费者引用时,url需要带上应用上下文,否则也无法访问.
4. 针对servlet的服务,端口和上下文必须与应用服务器的端口及上下文保持一致.

遗留问题

1.dubbo-webservice与标准webservice的相互使用
