Answer 1

从该JSP的页面导入中的jva.util.Date导入日期

<%@page import="java.util.Date" %>

或使用

Date类的完全限定名称，如java.util.Date

 java.util.Date resultdate = new java.util.Date(Long.parseLong(starttime));

sql包Date和util Date class之间的不一致

Answer 2

我认为你导入了java.util.Date和javax.sql.Date。

尝试从import语句中删除javax.sql.Date。

org.apache.jasper.jasperexception无法为jsp编译类
