There are 3 Methods to pass values from one jsp to another. With a PathVariable:

将值从一个jsp传递到另一个jsp有3种方法。使用PathVariable：

<a href="site.jsp?var=${var}" />

With a hidden field:

隐藏字段：

<form method="post" action="next.jsp">    
   <input type="hidden" name="var" value="${var}">

Or with a Session object.

或者使用Session对象。

session.setAttribute("var", var);

You can get this with session.getAttribute(var) on the next jsp.

您可以在下一个jsp上使用session.getAttribute（var）获取此信息。
