org.apache.jasper.JasperException: Unable to compile class for JSP:

出现这种情况往往都是在 include 多个JSP页面后出现，报错信息为:

 ERROR LogErrorInfoImpl:42 - Error Happen:

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.

这是因为JSP页面过大导致的，我们只需要更改Tomcat的web.xml配置文件即可解决

<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>
<init-param>
<param-name>enablePooling</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>mappedfile</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>

在web.xml中添加上段红色代码，之后重启Tomcat再次即可。
