spring使用RMI暴露服务

(1)定义接口：

package com.logcd.spring.rmi;

public interface HelloService {
	public String doHello(String name);
}

(2)接口实现:

package com.logcd.spring.rmi;

public  class HelloServiceImpl implements HelloService{

	public String doHello(String name) {
		return "Hello , " + name;
	}

}

(3)rmi-server.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN" 
  "http://www.springframework.org/dtd/spring-beans.dtd"> 

<beans> 
    <bean id="helloService" class="com.logcd.spring.rmi.HelloServiceImpl"/>

	<!--RmiServiceExporter显示地支持使用RMI调用器暴露任何非RMI服务-->
    <bean id="serviceExporter" 
class="org.springframework.remoting.rmi.RmiServiceExporter">

        <property name="service" ref="helloService"/>
        <property name="serviceInterface"
           value="com.logcd.spring.rmi.HelloService"/>
        <!--定义要暴露的服务名可以与输出的bean不同名，客户端通过这个名字来调用服务-->
        <property name="serviceName" value ="HelloService"/>
        <!--覆盖RMI注册端口号(1099)，通常应用服务器也会维护RMI注册，最好不要冲突-->
        <property name="registryPort" value="1199"/>
    </bean>
    
</beans>

(4)rmi-client.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN"
   "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<!--使用RmiProxyFactoryBean连接服务端-->
     <bean id="serviceProxy" 
               class="org.springframework.remoting.rmi.RmiProxyFactoryBean">

        <property name="serviceUrl"
	                value="rmi://localhost:1199/HelloService"/> 
        <property name="serviceInterface"
                  value="com.logcd.spring.rmi.HelloService"/>
     </bean>
</beans>

(5)测试

package com.logcd.spring.rmi;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpringRMI {
	
	public static void main(String args[]){
	   ApplicationContext context= new ClassPathXmlApplicationContext(
				new String[]{"rmi-server.xml","rmi-client.xml"}); 
	   
	   HelloService service = (HelloService)context.getBean("serviceProxy");
	   
	   System.out.println(service.doHello("logcd"));
	}
	
}
