這是因為struts2的過濾器，解決方法是自定義一個過濾器

新建一個過濾器的類，代碼：

 1 package com.filter; 2  3 import java.io.IOException; 4  5 import javax.servlet.FilterChain; 6 import javax.servlet.ServletException; 7 import javax.servlet.ServletRequest; 8 import javax.servlet.ServletResponse; 9 import javax.servlet.http.HttpServletRequest;10 11 import org.apache.struts2.dispatcher.ng.filter.StrutsPRepareAndExecuteFilter;12 13 public class EditorStrutsFilter extends StrutsPrepareAndExecuteFilter{14     public void doFilter(ServletRequest req, ServletResponse res,15             FilterChain chain) throws IOException, ServletException {16         HttpServletRequest request = (HttpServletRequest) req;17         String url = request.getRequestURI();        18         System.out.println(url);        19         if (url.contains("/jsp/")) {            20             System.out.println("使用自定義過濾器");            21             chain.doFilter(req, res);        22         }else{            23             System.out.println("使用默認過濾器");            24             super.doFilter(req, res, chain);        25         }26     }

之后在web.xml里面配置struts2過濾器

1     <filter>2         <filter-name>struts2</filter-name>3         <filter-class>com.filter.EditorStrutsFilter</filter-class>4     </filter>5     <filter-mapping>6         <filter-name>struts2</filter-name>7         <url-pattern>/*</url-pattern>8     </filter-mapping>

注意，如果有

1 　　<filter>2         <filter-name>struts2</filter-name>3         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>4     </filter>

要將其刪除
