这个第一次访问的时候是正常的访问之后刷新才出错 --------------------编程问答-------------------- NullPointerException，说明不能重复提交。第二次不能提交，当然就是空指针异常了。可以配置试图，或者进行友好提示，比如提交按钮置灰等。 --------------------编程问答--------------------
我不是配置了struts里面的token，按正常程序应该是跳转那个index.jsp的而且我测试
xwork-core-2.1.6.jar
struts2-core-2.1.8.jar
这个包下运行是正常的
--------------------编程问答-------------------- 在jsp上加上 <s:actionerror />
<s:token></s:token>改为<s:token/>
试下，看显示的什么信息 --------------------编程问答--------------------
--------------------编程问答--------------------

就是那个500 --------------------编程问答-------------------- <result name="invalid.token">/index.jsp</result>

这样也不行
大神，要不我把源码发给你试试？ --------------------编程问答-------------------- 给个邮箱或者qq
--------------------编程问答-------------------- ftp://lastpring@221.231.138.75/wwwroot/down/struts2.rar
这是一个正确版本一个错误版本的源码，求大神有空给看一下到底啥原因哇· --------------------编程问答-------------------- 参考下：
http://www.iteye.com/topic/399518 --------------------编程问答--------------------
谢谢，好了 --------------------编程问答-------------------- 今天也遇到了和你同样的问题，我用的是struts-core-2.3.12，xwork-core-2.3.12的包，后来经过我的测试，你可以把你的action继承ActionSupport，这样这个问题就可以解决了。呵呵，虽然发现的比较晚，但是希望还是对你有帮助。虽然找到了原因，但是还真的不知道为什么要这样做。估计只有继承ActionSupport，token的拦截器才会起作用吧。 --------------------编程问答--------------------
果然，我之前是implements Action出现了和楼主一样的错误，改了extends ActionSupport，就好了。 --------------------编程问答--------------------
但是更苦逼的事出现了，单独这样用还行，如果一旦struts与spring一整合就悲剧了，提交后的第一次重复提交还会正常运行，第二次以后的所有重复提交都会出现No result defined for action action.LoginAction and result input的错误，郁闷了哦，最后只好把action的class设为包括包名的全称，但这样又没和spring整合在一起，苦逼哦 --------------------编程问答--------------------
我知道我哪里错了，Spring的Bean是单例模式，而action是每一次请求就生成一个action，我去 --------------------编程问答--------------------
me too
补充：Java , Web 开发
