这是我的配置文件 --------------------编程问答-------------------- 顶上去。。。我用androidpn也是这个问题。。。困扰了很久很久。。
windows下完全没问题 但是在mac下就直接
An error occurred
javax.servlet.ServletException: Servlet.init() for servlet dispatcher threw exception --------------------编程问答-------------------- 没碰到过，如果有时间建议用虚拟机多装几个linux 版本和java版本测试下 --------------------编程问答-------------------- 我也遇到同样问题，请问楼主解决没有？ --------------------编程问答-------------------- 我也遇到这样的问题，现在一直没有找到解决的办法!!已经折腾了好久了！ --------------------编程问答-------------------- 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");
--------------------编程问答--------------------
--------------------编程问答--------------------
我去，我也是遇到这个问题，下载狂郁闷
--------------------编程问答--------------------
同样是androidon的，貌似网上的androidpn都或多或少有点毛病
--------------------编程问答--------------------
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。 --------------------编程问答-------------------- 搞定了没哥们？？？？同样的问题啊 --------------------编程问答-------------------- 我也遇到同样的问题，有大牛解决了吗，分享一下经验，感谢！ --------------------编程问答-------------------- 我也遇到同样的问题。。。。悲剧，哪位大神能解决的啊！！
补充：Java , Web 开发
