Хорошо, это сводит меня с ума!Не могу понять это.
У меня есть веб-сервис с пружинной загрузкой, который должен работать 24/7.Я подключаюсь к mysql используя пул соединений (используя hikariCP).
В настоящее время в dev env работа выполняется только один раз в день.Таким образом, в течение 23 часов соединения простаивают.
Когда запланированное задание выполняется по какой-то причине, оно выполняется в свободном потоке и выдает исключение, указанное ниже, даже если до этого Hikari четко показывал, что создал новое соединение, в пределах порога времени ожидания.
Я не могу воспроизвести это сам после нескольких минут / часов простоя, это происходит только после этого длительного периода.Я пробовал следовать настройкам из нескольких предложений на других сообщениях / сайтах, но я не получаю.Надеясь, что это что-то простое, я упустил из виду, что кто-то может мне помочь.
Спасибо
