错误信息

org.apache.jasper.JasperException: Unable to compile class for JSP:An error occurred at line: 158 in the generated java fileThe 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>
