tomcat的jsp页面超过65535，导致500报错

错误信息

       org.apache.jasper.JasperException: Unable to compile class for JSP:
       An error occurred at line: 158 in the generated java file
       The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit.
   
  

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>
