导出EXCEL报错:NullPointerException

报的错误是：

org.apache.jsp.jsp. _jspInit 第33行错误

public void _jspInit() {

    _005fjspx_005ftagPool_005fs_005fiterator_0026_005fvalue = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());

    _005fjspx_005ftagPool_005fs_005fproperty_0026_005fvalue_005fnobody = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());

    _005fjspx_005ftagPool_005fs_005fif_0026_005ftest = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());

    _005fjspx_005ftagPool_005fs_005felseif_0026_005ftest = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());

    _005fjspx_005ftagPool_005fs_005felse = org.apache.jasper.runtime.TagHandlerPool.getTagHandlerPool(getServletConfig());

    _el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory();--错误

    _jsp_annotationprocessor = (org.apache.AnnotationProcessor) getServletConfig().getServletContext().getAttribute(org.apache.AnnotationProcessor.class.getName());

  }

--------GOOGLE 后据说是tomcat的包放入了web-inf/lib 下

 把tomcat的JAR报删除即可

重新运行，功能OK
