struts2 web.xml中配置问题

[catechu]

为什么我在web.xml中增加
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.Dispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
以上内容以后再启动TOMCAT以后报错,

但是我把LOG4J的JAR包放到WEB-INF/LIB目录下以后启动是没有问题了,但是浏览工程下的JSP页面,总是提示HTTP Status 404 这样的错误,找不到页面,


是怎么回事了,

[yebing0736]

<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


应该这样配置.

你是不是采用了 Apache Struts的服务器架构啊,如果是,可能是你的Apache没有配置到你的网站目录.

[catechu]

没有吧,问题是启动TOMCAT都报错呀

[zidasine]

类名写错了

<filter-class>
			org.apache.struts2.dispatcher.FilterDispatcher
		</filter-class>

[catechu]

<filter>
<filter-name>struts2 </filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2 </filter-name>
<url-pattern>/* </url-pattern>
</filter-mapping>


这个是正确的



再启动不报错了.

我也遇到这样的问题，我以为是版本问题，换了几个，还是没有解决。

刚遇到楼主一样的问题，但是我的还是没解决，

[spacewalkerht]

我也遇到了，没解决

[MeLoveVc]

大家都解决问题了么？

[woshiduyongchang]

重新建一个就可以了

[独梦男孩]

我也遇到了，可是不行

[yinshunhui]

配置问题，还有就是不同的版本配置不一样。找到适合自己的版本配置
