The code of method _jspService(HttpServletRequest,
HttpServletResponse) is exceeding the 65535 bytes limit Stacktrace:

原因：JSP文件太大导致此错误。
解决方法：修改Tomcat安装目录下conf文件夹下的web.xml文件，搜索JspServlet，添加如下代码：

<init-param>
    <param-name>mappedfile</param-name>
    <param-value>false</param-value>
</init-param>

如图：
