Как проанализировать место создания потока на основе jstack？ ⇐ JAVA

[Anonymous]

Я столкнулся с проблемой: у службы много потоков, около 3000 или около того. Я проверил информацию о потоке в jstack, но не смог увидеть, где поток был создан в службе.
Конкретная информация о стеке потоков следующая:

Это демон false
Приоритет 5
Состояние [активно, припарковано, ожидание, ожидание неопределенное время]
Значение состояния 0x291
Всего: 10 записей.
Выполните поиск кода, связанного с потоком, и найдите следующие два места.
Одно в методе:< /p>

Код: Выделить всё

Executor executor = ThreadUtil.newExecutor(3, 6, 30000);

Одна из них — глобальная переменная класса.

Код: Выделить всё

ExecutorService executor = ExecutorBuilder.create()
.setCorePoolSize(5)
.setMaxPoolSize(10)
.setWorkQueue(new LinkedBlockingQueue(10000))
.build();
