Настройка пула соединений с mybatis + spring

Question

Я использую mybatis, настроенный с пружиной.Все работает нормально, но в этой конфигурации нет пула соединений.Каждый раз, когда я выполняю какой-то оператор SQL, он создает новое соединение.Есть ли простой способ, как настроить пул соединений с mybatis + spring?

Вы можете обратиться к моей конфигурации ， Я использовал druid в качестве пула соединений:
