Java堆內存休眠

-1

在我的應用我有一個堆內存例外：我增加與JVM參數堆內存，但它並沒有解決問題：這裏是例外：Java堆內存休眠

也許某些惡意實體映射（導致循環引用） – Antoniossss

您可以粘貼Session初始化和查詢執行的代碼嗎？ –

請檢查與您同樣問題的其他問題。也許是相同的原因：http://stackoverflow.com/questions/30234995/hibernate-java-lang-outofmemoryerror-java-heap-space –

檢查您是否通過某種單例機制獲取SessionFactory的實例。當我開始學習hibernate時，我遇到了這個問題。您可以使用jconsole來檢查jvm的性能。在命令提示符下鍵入jconsole並檢查性能變化並優化代碼
