У меня есть этот код в службе

 val user = userRepo.findById(id).orElseThrow { UsernameNotFoundException("User with id $id was not found.") }
 

и в контроллере

 @ExceptionHandler
    fun handleUsernameNotFoundException(e: UsernameNotFoundException) {
        throw ResponseStatusException(HttpStatus.NOT_FOUND, e.localizedMessage)
    }
@PreAuthorize("somecheck('PUT user/{id}') || othercheck(#id)")
@PutMapping("/{id}")
fun update(@PathVariable id: UUID, @RequestBody @Valid data: Data) =
    service.update(id, data)
 

Если я помещаю точку останова внутри обработчика или службы (или что-то в системе), оно явно выполняется. Несмотря на это, ответ 401 неавторизован. Очевидно, что запрос авторизован, потому что, если я передам правильный UUID, я смогу обновить данные.

Между тем в журналах:

Я понял! Похоже, что вы не можете создать другое исключение внутри ExceptionHandler. Правильный способ

 @ResponseStatus(HttpStatus.NOT_FOUND)
@ExceptionHandler(UsernameNotFoundException::class)
fun handleUsernameNotFoundException() {
    // nothing to do
}
