No mapping found for HTTP request with URI [/portal/download] in Dispatcherservlet with name ' Springmvc '

Tag: Class error servlet GPO patch BSP encountered parsing with ur

This article for Bo Master original, without permission not reproduced:

When you encounter this exception, summarize the cause of this problem:

This is because the request path is not resolved when the Dispatcherservlet is distributed in SPRINGMVC. The path to be requested in the background should be "/portal/download",

Because the first word in the portal is capitalized, it is not resolved to the path at the time of the request, so this error is reported.

Once modified, you can request it normally.

There is also a possibility that this error may be reported when the SPRINGMVC scan annotations are not scanned.
