Question

我使用strut2 + hibernate构建一个简单的项目。当我为这个项目启动tomcat时，它显示：

Exception starting filter [struts2]

严重: One or more Filters failed to start. Full details will be found in the appropriate container log file

严重: Context [/strut_test] startup failed due to previous errors

我尝试了很多方法来解决这个异常并在互联网上搜索信息。但是我不能解决这个问题。我是初学者，请帮助我。这是我的代码：

的web.xml

    </welcome-file-list>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>top.xgystudy.util.EditorStrutsFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

sturts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />
    <package name="default" namespace="/my_action" extends="struts-default">


         <action name="deal" class="top.xgystudy.action.Deal" method="add_article">

        </action>
        <action name="deal" class="top.xgystudy.action.Deal" method="he">
            <result>/r.jsp </result>

        </action>
           <action name="deal" class="top.xgystudy.action.Deal" method="show_article">
            <result>/show.jsp </result>

        </action>
    </package>
</struts>

EditorStrutsFilter.java ：这是我定义的新过滤器。

package top.xgystudy.util;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;

public class EditorStrutsFilter extends StrutsPrepareAndExecuteFilter {
    public void doFilter(ServletRequest req, ServletResponse res,
             FilterChain chain) throws IOException, ServletException {
         HttpServletRequest request = (HttpServletRequest) req;
         String url = request.getRequestURI();        
         System.out.println(url);        
         if (url.contains("/jsp/")) {            
             System.out.println("使用自定义过滤器");            
             chain.doFilter(req, res);        
         }else{            
             System.out.println("使用默认过滤器");            
             super.doFilter(req, res, chain);        
        }
     }
}

我也导入了罐子，包括：公地文件上传-1.3.1.jar
公地IO-2.4.jar
公地lang3-3.1.jar
共享记录-1.1.3.jar
freemarker的-2.3.19.jar
Javassist进行-3.15.0.GA.jar
OGNL-3.0.5.jar
Struts2的核心 - 2.3.4.jar
xwork-core-2.3.4.jar
