• Spring 4 整合RMI技术及发布多个服务(xjl456852原创)

    rmi需要建立两个项目,一个是服务端的项目,一个是客户端的项目.服务端项目启动后,再启动客户端项目去调用服务端的方法.

    我们建立两个maven项目:
    pom.xml配置:
    1. <?xml version="1.0" encoding="UTF-8"?>
    2. <project xmlns="http://maven.apache.org/POM/4.0.0"
    3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    88. </project>

    第一个是服务端的maven项目:
    服务接口，和以前不一样了，不用实现远程接口了。HelloService:
    1. package com.xjl456852.rmi.spring;
    3. /**
    4. * 定义一个远程接口 
    5. * 
    6. * @author leizhimin 2009-8-17 13:53:38 
    7. */ 
    9. public interface HelloService { 
    11.         /** 
    12.          * 简单的返回“Hello World！"字样 
    13.          * 
    14.          * @return 返回“Hello World！"字样 
    15.          */ 
    16.         public String helloWorld(); 
    18.         /** 
    19.          * 一个简单的业务方法，根据传入的人名返回相应的问候语 
    20.          * 
    21.          * @param someBodyName 人名 
    22.          * @return 返回相应的问候语 
    23.          */ 
    24.         public String sayHelloToSomeBody(String someBodyName); 
    25. }
    服务实现类,加入了注解:
    1. package com.xjl456852.rmi.spring;
    3. import org.springframework.stereotype.Service;
    5. /**
    6. * 远程的接口的实现 
    7. * 
    8. * @author leizhimin 2009-8-17 13:54:38 
    9. */
    10. @Service
    11. public class HelloServiceImpl implements HelloService {
    12.         public HelloServiceImpl() { 
    13.         } 
    15.         /** 
    16.          * 简单的返回“Hello World！"字样 
    17.          * 
    18.          * @return 返回“Hello World！"字样 
    19.          */ 
    20.         public String helloWorld() { 
    21.                 return "Hello World!"; 
    22.         } 
    24.         /** 
    25.          * 一个简单的业务方法，根据传入的人名返回相应的问候语 
    26.          * 
    27.          * @param someBodyName 人名 
    28.          * @return 返回相应的问候语 
    29.          */ 
    30.         public String sayHelloToSomeBody(String someBodyName) { 
    31.                 return "你好，" + someBodyName + "!"; 
    32.         } 
    33. }
    服务端启动程序:
    1. package com.xjl456852.rmi.spring;
    3. import org.springframework.context.ApplicationContext;
    4. import org.springframework.context.support.ClassPathXmlApplicationContext; 
    6. /** 
    7. * 通过Spring发布RMI服务 
    8. * 
    9. * @author leizhimin 2009-8-17 14:22:06 
    10. */ 
    11. public class HelloHost { 
    12.         public static void main(String[] args) { 
    13.                 ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
    14.                 System.out.println("RMI服务伴随Spring的启动而启动了....."); 
    15.         } 
    16. }

    Spring 配置: applicationContext.xml:
    1. <beans xmlns="http://www.springframework.org/schema/beans"
    2.        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
    3.        xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    4.        xmlns:task="http://www.springframework.org/schema/task"
    5.        xsi:schemaLocation="
    6.           http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    7.           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
    8.           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
    9.           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
    10.           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd">
    12.     <!-- component-scan自动搜索@Component , @Controller , @Service , @Repository等标注的类 -->
    13.     <context:component-scan base-package="com.xjl456852" />
    15.     <bean id="serviceExporter" class="org.springframework.remoting.rmi.RmiServiceExporter">
    16.         <property name="serviceName" value="rmiSpring"/>
    17.         <property name="serviceInterface" value="com.xjl456852.rmi.spring.HelloService"/>
    18.         <property name="registryPort" value="8888"/>
    19.         <property name="service" ref="helloServiceImpl"/>
    21.     </bean>
    22. </beans>
    启动服务端程序,HelloHost:
     

    第二个是客户端的maven项目:
    客户端调用有两种方式，一种是使用Spring，一种不使用，这里仅介绍使用Spring的情况。
    客户端需要依赖服务端的 HelloService接口,需要将这个接口放入到客户端中.

    客户端的启动类:
    1. package com.xjl456852.rmi.spring;
    3. import org.springframework.context.ApplicationContext; 
    4. import org.springframework.context.support.ClassPathXmlApplicationContext;
    6. import javax.annotation.Resource;
    7. import java.rmi.RemoteException; 
    9. /** 
    10. * 通过Spring来调用RMI服务 
    11. * 
    12. * @author leizhimin 2009-8-17 14:12:46 
    13. */ 
    14. public class HelloClient {
    15.         @Resource
    16.         private HelloService helloService; 
    18.         public static void main(String[] args) throws RemoteException { 
    19.                 ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); 
    20.                 HelloService hs = (HelloService) ctx.getBean("helloService"); 
    21.                 System.out.println(hs.helloWorld()); 
    22.                 System.out.println(hs.sayHelloToSomeBody("xjl456852")); 
    23.         } 
    25.       
    26. }

    在Spring中配置客户端要调用服务, applicationContext.xml:
    1. <beans xmlns="http://www.springframework.org/schema/beans"
    2. 	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
    3. 	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    4. 	xmlns:task="http://www.springframework.org/schema/task"
    5. 	xsi:schemaLocation="
    6.           http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    7.           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
    8.           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
    9.           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
    10.           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd">
    12. 	<!-- component-scan自动搜索@Component , @Controller , @Service , @Repository等标注的类 -->
    13. 	<context:component-scan base-package="com.xjl456852" />
    14. 	<bean id="helloService" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
    15. 		<property name="serviceUrl" value="rmi://192.168.176.131:8888/rmiSpring"/>
    16. 		<property name="serviceInterface" value="com.xjl456852.rmi.spring.HelloService"/>
    17. 	</bean>
    18. 	
    19. 	
    20. </beans>


    启动客户端,查看结果:
     

    下面是服务端发布多个服务接口的配置:
    假设服务端还有一个服务,叫OtherService:
    1. package com.xjl456852.rmi.spring;
    3. /**
    4.  * Created by xjl on 2017/3/19.
    5.  */
    6. public interface OtherService {
    8.     public int random();
    9. }
    服务端的实现类:
    1. package com.xjl456852.rmi.spring;
    3. import org.springframework.stereotype.Service;
    5. import java.util.Random;
    7. /**
    8.  * Created by xjl on 2017/3/19.
    9.  */
    10. @Service
    11. public class OtherServiceImpl implements OtherService{
    12.     Random random = new Random();
    13.     public int random() {
    14.         System.out.println("invoke random method");
    15.         return random.nextInt(100);
    16.     }
    17. }
    服务端的Spring配置:
    1. <beans xmlns="http://www.springframework.org/schema/beans"
    2.        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

    15.     <bean id="serviceExporter" class="org.springframework.remoting.rmi.RmiServiceExporter">
    16.         <property name="serviceName" value="rmiSpring"/>
    17.         <property name="serviceInterface" value="com.xjl456852.rmi.spring.HelloService"/>
    18.         <property name="registryPort" value="8888"/>
    19.         <property name="service" ref="helloServiceImpl"/>
    21.     </bean>
    23.     <bean id="serviceExporter_Other" class="org.springframework.remoting.rmi.RmiServiceExporter">

    26.         <property name="registryPort" value="8888"/>
    27.         <property name="service" ref="otherServiceImpl"/>
    29.     </bean>
    30. </beans>


    下面是客户端的配置:
    客户端需要依赖服务端的OtherService接口
    然后客户端的Spring配置如下:
    1. <beans xmlns="http://www.springframework.org/schema/beans"
