目标:启动一个支持远程访问方法调用的服务器.
在创建所有服务之后,应用程序不会失败.
jar位于target / lib目录中.
父pom具有依赖性:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${version.spring}</version>
</dependency>
注意:我能够创建一个类型为:org.springframework.aop.framework.ProxyFactory的spring bean

应用程序上下文服务网络的server.xml:
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<!-- does not necessarily have to be the same name as the bean to be exported -->
<property name="serviceName" value="Manager1" />
<property name="service" ref="manager1" />
<property name="serviceInterface" value="com.service.Manager1" />
<!-- defaults to 1099 -->
<property name="registryPort" value="1199" />
</bean>
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<!-- does not necessarily have to be the same name as the bean to be exported -->
<property name="serviceName" value="Manager2" />
<property name="service" ref="manager2" />
<property name="serviceInterface" value="com.service.Manager2" />
<!-- defaults to 1099 -->
<property name="registryPort" value="1199" />
</bean>
<bean id="manager1"
class="com.service.impl.Manager1Impl">
...
</bean>
<bean id="manager2"
class="com.service.impl.Manager2Impl">
...
</bean>
注意:这有效,但上述情况仍然失败
<bean id="proxied" class="org.springframework.aop.framework.ProxyFactory" />
Thread [main] (Suspended (entry into method in ProxyFactory)) ProxyFactory.() line: 40 NativeConstructorAccessorImpl.newInstance0(Constructor, Object[]) line: not available [native method] NativeConstructorAccessorImpl.newInstance(Object[]) line: 39 DelegatingConstructorAccessorImpl.newInstance(Object[]) line: 27 Constructor.newInstance(Object...) line: 494
解决方法:
请仔细检查您是否还具有以下依赖项:
> aopalliance.jar
> spring-core.jar
NoClassDefFoundError并没有说它找不到ProxyFactory类 – 事实上,它已被发现,但它的某些依赖项缺失了.
