Spring rmi

1.org.springframework.remoting.rmi.RmiProxyFactoryBean

其使用的是rmi协议实现

实现过程，首先是服务端

定义一个导出类

public  interface  AccountService {
    String getUsername();
}

 

public  class  AccountServiceImpl  implements  AccountService{
    @Override
    public  String getUsername() {
        return  "RMI Test!" ;
    }
}

 

rmi.xml

<? xml  version = "1.0"  encoding = "UTF-8" ?>
< beans  xmlns = "http://www.springframework.org/schema/beans"
       xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">
    < bean  id = "accountService"  class = "example.AccountServiceImpl" >
        <!-- any additional properties, maybe a DAO? -->
    </ bean >
    < bean  class = "org.springframework.remoting.rmi.RmiServiceExporter" >
        <!-- 这里的服务名可以随意填写但是必须和rmi://hostname:1199/xxxxxxx的xxxxxxx相同 -->
        < property  name = "serviceName"  value = "AccountService" />
        <!-- 导出实体 -->
        < property  name = "service"  ref = "accountService" />
        <!-- 导出接口，这个为导出接口，注意，客户端包名可以和这里不同，但是为了统一建议做一个coreInterface
            包，以便以后维护方便 -->
        < property  name = "serviceInterface"  value = "example.AccountService" />
        <!-- 端口号，默认为1099，这里注意占用问题 -->
        < property  name = "registryPort"  value = "1199" />
    </ bean >
</ beans >

 

启动服务

public  class  Main {
    public  static  void  main(String[] args) {
        ApplicationContext context =
                new  ClassPathXmlApplicationContext( "rmi.xml" );
        AccountService service = context.getBean( "accountService" , AccountService. class );
        String userName = service.getUsername();
        System.out.println(userName);
    }
}

 

 

接下来客户端如下

public  interface  AccountService {
    String getUsername();
}

 

rmi.xml

<?xml version= "1.0"  encoding= "UTF-8" ?>
<beans xmlns= "http://www.springframework.org/schema/beans"
       xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http: //www.springframework.org/schema/beans
        http: //www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id= "accountService"  class = "org.springframework.remoting.rmi.RmiProxyFactoryBean" >
        <!-- 接收的rmi协议 -->
        <property name= "serviceUrl"  value= "rmi://localhost:1199/AccountService" />
        <!-- 接收的rmi协议的接口 -->
        <property name= "serviceInterface"  value= "example.AccountService" />
    </bean>
</beans>

 

启动程序

public  class  Main {
    public  static  void  main(String[] args) {
        ApplicationContext context =
                new  ClassPathXmlApplicationContext( "rmi.xml" );
        AccountService service = context.getBean( "accountService" , AccountService. class );
        String userName = service.getUsername();
        System.out.println(userName);
    }
}

 

这样就可以在服务器端得到了RMI Test!

当我们在启动服务端的时候会发现，其控制台一直在运行状态，当结束后，还会有rmi进程在运行。其接口协议为rmi://hostname:1199/xxxxxxx
