1、操作程序，从tomcat的日志文件里查到报错信息如下：
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.
2、这是因为tocmat请求的url地址过长导致的，修改tomcat的web.xml文件后，程序恢复正常
3、在：
<init-param>
<param-name>enablePooling</param-name>
<param-value>false</param-value>
</init-param>
下添加
<init-param>
<param-name>mappedfile</param-name>
<param-value>false</param-value>
</init-param>
重启tomat即可恢复正常
