java - As shown in the figure, how is the action in the form of the jsp page mapped to this position? Why can it be mapped to save without writing dynUser?

Question

Shouldn’t it be written like this?
action="dynUsse/save"

Answer 1

Is there any basePath or something in JSP? Remember to add basePath and add the access path by default before the requested path!

Answer 2

See if this jsp file is in the dynuser folder. . . Relative paths will be added automatically.
