Spring整合Rmi总结

在Spring整合Rmi中:

服务端使用了org.springframework.remoting.rmi.RmiServiceExporter

RmiServiceExporter把任何Spring管理的Bean输出成一个RMI服务。通过把Bean包装在一个适配器类中工作。适配器类被绑定到RMI注册表中，并且将请求代理给服务类。

客户端使用了org.springframework.remoting.rmi.RmiProxyFactoryBean

客户端的核心是RmiProxyFactoryBean，包含serviceURL属性和serviceInterface属性。

通过JRMP访问服务。JRMP JRMP:java remote method protocol，Java特有的,基于流的协议。

 

下面给出简单例子

服务端程序：

新建接口：

 

<span style="font-size:18px;color:#3333ff;">/** 
 * IRmiServer.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-08-08 11:12:40 
 */  
package com.cayden.rmi;  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public interface IRmiServer {  
      
    public boolean test();  
  
}  
</span>

再实现该接口的方法：

<span style="font-size:18px;color:#3333ff;">/** 
 * RmiServerImpl.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-08-08 11:13:24 
 */  
package com.cayden.rmi.impl;  
  
import com.cayden.rmi.IRmiServer;  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public class RmiServerImpl implements IRmiServer {  
  
    /* (non-Javadoc) 
     * @see com.cayden.rmi.IRmiServer#test() 
     */  
    @Override  
    public boolean test() {  
      
        System.out.println("调用了我--服务端 O(∩_∩)O哈！");  
          
        return true;  
    }  
  
}  
</span>

在src下新建applicationContext.xml 配置文件

<span style="font-size:18px;color:#3333ff;"><?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.5//EN" "file:/usr/local/tomcat_report/lib/spring-beans-2.0.dtd">  
<beans>  
      
        <!-- rmi -->  
    <bean id="rmiService" class="com.cayden.rmi.impl.RmiServerImpl">  
    </bean>  
  
    <bean id="remoteRmiService" class="org.springframework.remoting.rmi.RmiServiceExporter">  
        <property name="serviceName">  
            <value>remoteService</value>  
        </property>  
        <property name="service" ref="rmiService" />  
        <property name="serviceInterface">  
            <value>com.cayden.rmi.IRmiServer</value>  
        </property>  
        <property name="registryPort">  
            <value>9400</value>  
        </property>  
        <property name="servicePort">  
            <value>9401</value>  
        </property>  
    </bean>  
</beans></span>

启动服务端的类【MainServer.java】

<span style="font-size:18px;color:#3333ff;">package com.cayden.rmi;  
  
import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
/** 
 * MainServer.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-08-08 11:44:07 
 */  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public class MainServer {  
  
    /** 
     * TODO 
     * @param args 
     */  
    public static void main(String[] args) {  
        // TODO Auto-generated method stub  
        System.out.println("rmi服务端启动");  
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");  
          
        System.out.println("rmi服务端启动完成。。。");  
    }  
  
}  
</span>

 

客户端代码：

在客户端使用服务端的接口文件：

<span style="font-size:18px;color:#3333ff;">/** 
 * IRmiServer.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-08-08 11:12:40 
 */  
package com.cayden.rmi;  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public interface IRmiServer {  
      
    public boolean test();  
  
}  
</span>

然后在src下新建【applicationContext.xml】

<span style="font-size:18px;color:#3333ff;"><?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.5//EN" "file:/usr/local/tomcat_report/lib/spring-beans-2.0.dtd">  
<beans>  
    <!-- rmi远程调用 -->  
    <bean id="testRmiService" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">  
        <property name="serviceUrl">  
            <value>rmi://127.0.0.1:9400/remoteService</value>  
        </property>  
        <property name="serviceInterface">  
            <value>com.cayden.rmi.IRmiServer</value>  
        </property>  
    </bean>  
</beans></span>

最新新建客户端的测试类【TestRmi.java】

<span style="font-size:18px;color:#3333ff;">/** 
 * TestRmi.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-08-08 11:38:06 
 */  
package com.cayden.rmi.client;  
  
import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
  
import com.cayden.rmi.IRmiServer;  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public class TestRmi {  
    public static void main(String[] arg) {  
        System.out.println("rmi客户端开始调用");  
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");  
        IRmiServer rmi=(IRmiServer)ctx.getBean("testRmiService");  
        rmi.test();  
        System.out.println("rmi客户端调用结束");  
    }  
  
}  
</span>

 

最后控制台输出

服务端：

<span style="font-size:18px;color:#3333ff;">rmi服务端启动  
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).  
log4j:WARN Please initialize the log4j system properly.  
rmi服务端启动完成。。。  
调用了我--服务端 O(∩_∩)O哈！  
</span>

客户端：

<span style="font-size:18px;color:#3333ff;">rmi客户端开始调用

</span>
