RMI

1. 发布RMI服务

在Spring配置文件中

 <!-- RMI配置参数-->
 <bean id="rmiServerHost" factory-method="setProperty" class="java.lang.System" lazy-init="false">
     <constructor-arg value="java.rmi.server.hostname"/>
     <constructor-arg value="${ipAddress}"/>
 </bean>

<!--
 <bean factory-method="setProperty" class="java.lang.System" lazy-init="false">
     <constructor-arg value="java.rmi.dgc.leaseValue"/>
     <constructor-arg value="300000"/>
 </bean>

 <bean factory-method="setProperty" class="java.lang.System" lazy-init="false">
     <constructor-arg value="java.rmi.dgc.gcInterval"/>
     <constructor-arg value="900000"/>
 </bean>

-->

<!-- 
接口IService
类Service实现IService　　
-->

<bean id="serviceExporter" class="org.springframework.remoting.rmi.RmiServiceExporter">
    <property name="service" ref="Service" />        　　　 　//服务接口的实现类
    <property name="serviceName" value="MyService" /> 　　　　//自定义服务名称
    <property name="serviceInterface" value="IService" /> 　 //服务接口
    <property name="registryPort" value="9000" /> 　　　　    //端口　　　 
</bean>

2. 客户端调用

a.

public static IService getService(String url){
        try {
            RmiProxyFactoryBean rmiProxyFactoryBean = new RmiProxyFactoryBean();
            rmiProxyFactoryBean.setServiceUrl(url);
            rmiProxyFactoryBean.setServiceInterface(IService.class);
            rmiProxyFactoryBean.setRefreshStubOnConnectFailure(true);
            rmiProxyFactoryBean.afterPropertiesSet();
            IService service = (IService)rmiProxyFactoryBean.getObject();

            return service;

        }catch (Exception e){
            throw new RuntimeException("获取程序服务[" + url + "]出错", e);
        }
    }

//url的格式为 rmi://ip:port/ServiceName 如：rmi://127.0.0.1:9000/MyService

b.

在spring配置文件中

<bean id="service" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
    <!-- 接收的rmi协议 -->
    <property name="serviceUrl" value="rmi://127.0.0.1:9000/MyService"/>
    <!-- 接收的rmi协议的接口 -->
    <property name="serviceInterface" value="IService"/>
</bean>

//注入到Test类中
<bean id="test" class="com.qinh.Test">
　　<property name="service" ref="service"/>
</bean>
