Spring 集成 RMI

Maven

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-remoting</artifactId>
        </dependency>

服务端

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

    <bean id="hello" class="org.zln.bdrisk.col.HelloImpl"/>

    <bean class="org.springframework.remoting.rmi.RmiServiceExporter">
        <!-- RMI服务名称,可自定义服务名称 -->
        <property name="serviceName" value="helloService" />
        <!-- 导出实体 -->
        <property name="service" ref="hello" />
        <!-- 导出接口 -->
        <property name="serviceInterface" value="org.zln.bdrisk.col.IHello" />
        <!-- spring默认使用1099端口 -->
        <property name="registryPort" value="8888" />
    </bean>

</beans>

客户端

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

       http://www.springframework.org/schema/context/spring-context-3.2.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">

    <bean id="hello" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
        <property name="serviceUrl" value="rmi://localhost:8888/helloService" />
        <property name="serviceInterface" value="org.zln.bdrisk.col.IHello" />
    </bean>
</beans>

说明：服务端只有Spring实例化了，RMI服务对象就会注册好等着被调用，客户端上填写好服务端的地址和服务名，然后从Spring容器中获取远程对象即可

RMI与Spring集成后，编写RMI服务类和普通的接口、实现没有区别，不再需要集成、跑出指定异常等

RMI的限制：1、客户端和服务端都必须是Java  2、对地址、端口的依赖
