Spring HttpInvoker(一)

一： 暴露服务(Spring mvc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;
  }
}

通过Spring mvc暴露服务

web.xml
<!-- DispatcherServlet -->
  <servlet>
    <servlet-name>Spring-DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/config/applicationContext-server.xml</param-value>
    </init-param>
  </servlet>

  <servlet-mapping>
    <servlet-name>Spring-DispatcherServlet</servlet-name>
    <url-pattern>*.service</url-pattern>
  </servlet-mapping>

applicationContext-server.xml
  <bean id="defaultSayHelloService" class="com.xx.service.impl.DefaultSayHelloServiceImpl" />

  <bean id="sayHelloServiceExporter" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter" >
    <property name="service"      ref="defaultSayHelloService" />
    <property name="serviceInterface"   value="com.xx.service.ISayHelloService" />
  </bean>

  <bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
      <property name="urlMap">
      <map>
        <entry key="/defaultSayHelloService.service" value-ref="sayHelloServiceExporter" />
      </map>
    </property>
  </bean>

二：引用服务

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/httpInvoker/defaultSayHelloService.service" />
    <property name="serviceInterface"   value="com.xx.service.ISayHelloService"/>
  </bean>

public class ClientMain {

  private static final DefaultListableBeanFactory beanFactory;

  static {
    beanFactory = new DefaultListableBeanFactory();
    BeanDefinitionReader beanDefinitionReader = new XmlBeanDefinitionReader(beanFactory);
    Resource resource = new ClassPathResource("applicationContext-client.xml");
    beanDefinitionReader.loadBeanDefinitions(resource);
  }

  public static void main(String[] args) {
    ISayHelloService sayHelloService = beanFactory.getBean("sayHelloService", ISayHelloService.class);
    System.out.println(sayHelloService.doSayHello("王五"));
  }
}
