我有1个JSP，比如说1.jsp，其中我有一个值，该值是从Action类的request.getAttribute("testvalue")中获取的，因为我正在使用Struts框架.我需要将此值从1.jsp发送到另一个2.jsp.请让我知道该怎么做?

推荐答案

从请求中获取值，您应该在请求中添加值.这段代码

Getting value from the request, you should be putting a value to a request. This code

request.getAttribute("testvalue");

正在获取值，但是该代码

is getting a value, but that code

request.setAttribute("testvalue", value);

正在放它.

这是因为您要避免使用HTTP会话.

This is because you want to avoid using the HTTP session.
