Jpa2/hibernate c3p0池配置导致连接和线程泄漏
我试图在我的应用程序中使用 c3p0 作为连接池提供程序(jpa 2 和 hibernate core 3.3.2),但 c3p0 从数据库获取太多连接。这是同样的问题,但答案不是有帮助。我从实体管理器工厂获取实体管理器并将实体管理器存储在线程局部变量中,因此我为每个请求使用一个新的实体管理器。(顺便说一句,如果我使用休眠默认池没有问题)

I am trying to use c3p0 as connection pool provider in my application (jpa 2 and hibernate core 3.3.2) but c3p0 getting too much connection from database.This is same problem but answer not helped.I am getting entitymanager from entitymanager factory and storing entitymanager in a thread local variable,thus a am using a fresh entiymanager for each request.(by the way if i use hibernate default pool no problem)

您能否确保没有在数据源和 sessionFactory 级别定义池。
Can you ensure that you are not defining pool at both datasource and sessionFactory level.
