Spring HttpInvoker(二)

一： 暴露服务(HttpRequestHandlerServlet 暴露服务)

package com.xx.service;

public interface ISayHelloService {

  /**
   * @param name
   * @return
   */
   String doSayHello(String name);
}

package com.xx.service.impl;

import com.xx.service.ISayHelloService;

public class DefaultSayHelloServiceImpl implements ISayHelloService {

  public String doSayHello(String name) {
    return "hello, " + name;
  }
}

web.xml
  <!-- ContextLoaderListener  -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/config/applicationContext-server.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- HttpRequestHandlerServlet -->
  <!-- servlet-name 必须和暴露的seviceProxy bean id相同    -->
  <servlet>
    <servlet-name>sayHelloServiceExporter</servlet-name>
    <servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>sayHelloServiceExporter</servlet-name>
    <url-pattern>/sayHelloService.service</url-pattern>
  </servlet-mapping>

applicationContext-server.xml
  <bean id="defaultSayHelloService" class="com.xx.service.impl.DefaultSayHelloServiceImpl" />
  <!--  和web.xml servlet-name 一致 -->  
  <bean id="sayHelloServiceExporter" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter" >
    <property name="service"      ref="defaultSayHelloService" />
    <property name="serviceInterface"   value="com.xx.service.ISayHelloService" />
  </bean>

二：客户端

package com.xx.service;

public interface ISayHelloService {

  /**
   * @param name
   * @return
   */
   String doSayHello(String name);
}

applicationContext-client.xml
  <bean id="sayHelloService"  class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
    <property name="serviceUrl"     value="http://localhost:8080/httpInvoker2/sayHelloService.service" />
    <property name="serviceInterface"   value="com.xx.service.ISayHelloService"/>
  </bean>

public class ClientMain {

  public static void main(String[] args) {
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-client.xml");
    ISayHelloService sayHelloService = applicationContext.getBean("sayHelloService", ISayHelloService.class);
    System.out.println(sayHelloService.doSayHello("王五"));
  }
}
