Re-continuation of converting action to JSP

It may be a very basic problem, but it is a problem that many friends have not understood. I also checked Servlet and Struts to find a solution to the problem.
Problem:

Use request. setattribute ("name", value. the findforward ("Forwards") method is redirected, but the passed attribute value cannot be obtained on the corresponding JSP page.
Solution:
We can choose not to select redirect when selecting forwards when creating an action, or in the struts-config.xml configuration file, it will correspond to the <forward> label in the <action> label, set "Redirect" to false.

Cause:
Because the request lifecycle is valid only for one request, if reditect is used, the request will be redirected, that is, the request lifecycle will be destroyed and a request will be re-generated, request. attributes set by setattribute are cleared.
