Question

也许这个问题看起来很重复，但是我花了很多时间阅读论坛并试图弄清楚我的代码出了什么问题。运行服务器时，我收到log4j机制提供的以下消息：

21 Apr 2019 14:39:11,707 DEBUG org.springframework.remoting.rmi.RmiServiceExporter 404 getRegistry - RMI registry access threw exception

我得到以下两个例外：

spring-server.xml文件中的代码是：


    <bean class="org.springframework.remoting.rmi.RmiServiceExporter">

        <property name="serviceName" value="Reservation"/>
        <property name="service" ref="reservationService"/>
        <property name="serviceInterface" value="services.IReservationServer"/>
        <property name="servicePort" value="1099"/>

    </bean>

我尝试了多种方法来解决该问题，包括设置以下两个属性：

   <property name="registryHost" value="169.254.144.79"/>
   <property name="registryPort" value="1099"/>

我还设置了此属性：

System.setProperty("java.rmi.server.hostname","169.254.144.79");

或

System.setProperty("java.rmi.server.hostname","127.0.0.1");

我什至禁用了Windows Defender防火墙，但没有任何效果。

尝试创建RmiServiceExporter对象时，为什么拒绝与本地主机的连接？
