Rules for turning to htaccess 301 after WordPress fixed link change

The current WordPress fixed link format is
/% Category %/% year %-% monthnum %-% day %/Your postname).html

Change
Article/% postname %/

How to write the 301 redirection rule in htaccess?

I have a stupid idea here. I don't know if this is feasible.
I have exported all the current addresses of all the articles.
Can I add rules in htaccess to direct all these links to the corresponding new link?

For example
The original link address of one of the links:

Http://baidu.com/my-interests/computer-applications/2010-04-02/gravatar.html

Turn

Http://baidu.com/article/gravatar/

 

Redirection after modifying the WordPress Fixed Link
This can be solved through two WordPress plug-ins
The two plug-ins are named Permalinks Moved Permanently and Redirection respectively.
