Я получаю эту ошибку случайным образом при доступе к веб-службе. Трудно реплицироваться, и как только я обновляю его, все работает так, как ожидалось.jdbc begin failed

Это мой hibernate.properties файл

рассматривается ошибка случайным образом один раз, и это занимает много времени, прежде чем он reappears.It уходит, как только обновляется.
Даже после добавления c3p0.testConnectionOnCheckin = верно Я получаю ту же ошибку. Я также добавил autoReconnect? = True для URL-адреса базы данных. Но все та же ошибка. – icedek
Извините за задержку в ответе на ваш комментарий и спасибо за добавление трассировки стека исключений. Когда возникло исключение 'java.net.SocketException: Broken pipe', его причина, возможно, в стороне« База данных », пожалуйста, измените поставщика базы данных, для примера используйте« MySql »или« Derby »или другие для тестирования. – MJM
