谁能帮帮小弟。初学Struts2...
我用的是My Eclipse8.0 Tomcat6.0 Struts2.1.8.1包

Answer 1

如果你使用的是struts2.1.8 那么配置web.xml中struts2的过滤时，调用的类和2.0有所不同，应该改成

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

最好再把你的配置文件粘出来，web.xml和struts.xml

Answer 2

你使用的过滤器在lib里没有找到。

你看下你那个包里面struts-default.xml文件的第70的定义中，那个类能不能找到。

Answer 3

你用struts2-core-2.1.8.1.jar
还用了ognl
是不是写了<s:text>标记？
用2.1.2版本吧，新版的有点问题....

Answer 4

/*代表过滤器拦截所有的请求，也就是说不管你访问的后缀名是什么如jsp，action，do他都拦截
而*.action代表过滤器只拦截以action结尾的请求，其他的如jsp，do结尾的都不管

Answer 5

Hi我

Answer 6

struts2-core-2.1.8.1.jar有这个包吗？
