解决方法： netstat -anp|grep 5222 查看　5222是否被占用如果被占用就会出现上面问题先关掉 tomcat /usr/local/tomcat/bin$ . shutdown.sh 然后　kill -9 pidXXX 杀掉占用5222的进程上面问题就会解决。

如果是window下无错误换了个环境就不行的话要么就是你Linux服务器环境变量等运行环境没搭建好要么就是你用的包不支持Linux的坦白讲我两个都用没发生过你说的问题，看你抛出的异常，我觉得可能是后者的情况，spring和servlet的支持包不行，你上网搜搜。

同样是androidon的，貌似网上的androidpn都或多或少有点毛病

貌似主要是这个bean无法创建引起的

<bean id="userController" class="org.androidpn.server.console.controller.UserController">         
    <property name="methodNameResolver" ref="paramResolver" />     
</bean>

仔细检查一下吧，手动能创建吗 JavaConfigApplicationContext context = new JavaConfigApplicationContext(...); Service service = (Service) context.getBean("userController");
