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
