解决办法

找到tomcat的web.xml文件，搜索fork，找到如下代码

   

    

     

      

     
     

      

       <servlet>
      
     
    

     

      

     
     

      
    <servlet-name>jsp</servlet-name>
      
     
    

     

      

     
     

      
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
      
     
    

     

      

     
     

      
    <init-param>
      
     
    

     

      

     
     

      
        <param-name>fork</param-name>
      
     
    

     

      

     
     

      
        <param-value>false</param-value>
      
     
    

     

      

     
     

      
    </init-param>
      
     
    

     

      

     
     

      
    <init-param>
      
     
    

     

      

     
     

      
        <param-name>xpoweredBy</param-name>
      
     
    

     

      

     
     

      
        <param-value>false</param-value>
      
     
    

     

      

     
     

      
    </init-param>
      
     
    

     

      

     
     

      
    <load-on-startup>3</load-on-startup>
      
     
    

     

      

     
     

      

       </servlet>
      
     
   
  

增加配置

   

    

     

      

     
     

      

       <init-param>
      
     
    

     

      

     
     

      
    <param-name>mappedfile</param-name>
      
     
    

     

      

     
     

      
    <param-value>false</param-value>
      
     
    

     

      

     
     

      

       </init-param>
