Spring中HttpInvoker实例

Spring版本2.5.6.SEC01

1.服务端：

需要如下jar包：spring.jar spring-webmvc.jar

IPersonService.java

public interface IPersonService { public String queryPersonName(); }

PersonServiceImpl.java

public class PersonServiceImpl implements IPersonService { public String queryPersonName() { return "test"; } }

service-config.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> <beans> <bean id="personService" class="com.travelsky.angel.service.impl.PersonServiceImpl" /> <bean id="serviceExporter" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter"> <property name="service" ref="personService" /> <property name="serviceInterface" value="com.travelsky.angel.service.IPersonService" /> </bean> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/person.service">serviceExporter</prop> </props> </property> </bean> </beans>

web.xml添加如下代码

<servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/service-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>*.service</url-pattern> </servlet-mapping>

2.客户端：

客户端需要应用服务端的bean和接口，另外需要spring.jar

HttpInvokerClient.java

public class HttpInvokerClient { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("httpinvoker-client.xml"); IPersonService service = (IPersonService) context.getBean("personServiceProxy"); String result = service.queryPerson(); System.out.println(result); } }

httpinvoker-client.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> <beans> <bean id="personServiceProxy" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean"> <property name="serviceUrl" value="http://127.0.0.1:8080/ProjectContextRoot/person.service" /> <property name="serviceInterface" value="com.travelsky.angel.service.IPersonService" /> </bean> </beans>

注意：ProjectContextRoot对应.mymetadata中的context-root，如果修改，需要重新启动Eclipse
