spring 远程调用

spring远程调用: ------------------------ -----------server----------- 1.创建web项目 2.添加spring类库 org.springframework.aop-3.1.0.RELEASE.jar org.springframework.asm-3.1.0.RELEASE.jar org.springframework.beans-3.1.0.RELEASE.jar org.springframework.context-3.1.0.RELEASE.jar org.springframework.context.support-3.1.0.RELEASE.jar org.springframework.core-3.1.0.RELEASE.jar org.springframework.web-3.1.0.RELEASE.jar org.springframework.web.servlet-3.1.0.RELEASE.jar org.springframework.expression-3.1.0.RELEASE.jar com.springsource.org.aopalliance-1.0.0.jar com.springsource.org.apache.commons.logging-1.1.1.jar 3.创建接口和实现类 public interface WelcomeService { public void sayHello(String name); } public class WelcomeServiceImpl implements WelcomeService { public void sayHello(String name) { System.out.println(name); } } 4.配置spring配置文件. [web-inf/${servler-name}-servlet.xml] <?xml version="1.0"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:cache="http://www.springframework.org/schema/cache" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd ">

<!-- pojo -->
<bean id="welcomeService" class="cn.itcast.spring.rpc.service.WelcomeServiceImpl" />

<!-- 导出器,将pojo对象转变成controller,处理请求 -->
<bean name="/ws.service" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<property name="serviceInterface">
<value>cn.itcast.spring.rpc.service.WelcomeService</value>
</property>
<property name="service" ref="welcomeService" />
</bean>
</beans> -----------client----------- 5.创建java项目 6.引入类库 同服务端. 7.复制服务端接口到客户端. 8.创建src/client.xml spring配置文件 <?xml version="1.0"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:cache="http://www.springframework.org/schema/cache" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd ">
<!-- 客户端代理 -->
<bean id="wsClient" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl">
<value>http://localhost:8080/lsn_springrpc_0909_server/ws.service</value>
</property>
<property name="serviceInterface">
<value>cn.itcast.spring.rpc.service.WelcomeService</value>
</property>
</bean>
</beans> 9.创建测试类 public class App { public static void main(String[] args) { ApplicationContext ac = new ClassPathXmlApplicationContext("client.xml"); WelcomeService ws = (WelcomeService) ac.getBean("wsClient"); ws.sayHello("tom"); } } 10.运行 先启动服务器端 在启动客户端. 将项目中的统计服务对外公开,供第三方系统整合 ------------------------------------------- --------- server --------- 1.引入类库 org.springframework.web.servlet-3.1.0.RELEASE.jar 2.配置web.xml文件DispatcherServlet <!-- 配置spring远程调用使用的分发器servlet -->
<servlet>
<servlet-name>service</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:service-spring-http-inovker.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>service</servlet-name>
<url-pattern>/*.service</url-pattern>
</servlet-mapping> 3.配置spring远程调用配置文件 [conf/service-spring-http-invoker.xml] <?xml version="1.0"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:cache="http://www.springframework.org/schema/cache" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd ">

<!-- 远程调用统计服务类 -->
<bean name="/ss.service" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<property name="serviceInterface" value="cn.itcast.surveypark.service.StatisticsService" />
<property name="service" ref="statisticsService" />
</bean>
</beans> ------- client ---------- 4.添加客户端配置bean. <!-- 客户端代理 -->
<bean id="ssClient" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl">
<value>http://localhost:8000/lsn_surveypark0909/ss.service</value>
</property>
<property name="serviceInterface">
<value>cn.itcast.surveypark.service.StatisticsService</value>
</property>
</bean> 5.测试
