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
