Got the 405 problem again. still the same old problem
Occurrence process: I wrote some new code, started debugging, and reported 405 in /oauth/token.
At that time, I remembered the last lesson after being stunned for 5 seconds, and quickly checked the newly written interface.
Sure enough, another @PutMapping() path was not written.
Change it to @PutMapping("/path") and restore it.
Lesson: Either don't write @RequestMapping, or write it all, and write the path together, otherwise 405
