休眠4 + C3P0连接池返回错误

2012-11-30 110 views
2

我使用Hibernate 4与C3P0作为其连接提供程序。我目前没有使用 Spring框架。即时通讯使用的休眠4 + C3P0连接池返回错误

开发环境

Windows 7 
Eclipse Juno 
JRE-7 
JDK -7

罐子......

hibernate-core-4.1.7.Final.jar 
c3p0-0.9.2-pre6.jar 
jtds-1.3.0.jar

但在相同的库路径也有

hibernate-c3p0-4.1.1.Final.jar 
spring-orm-3.2.0.RC1.jar

是否有机会与其他瓶子（hibernate-c3p0-4.1.1.Final.jar和spring-orm-3.2.0.RC1.jar）可能会对这个错误产生一些影响（见下文）？

是的，整个春天的框架罐子在路径上，但我只是想 习惯先休眠。我真的不知道如何使用Spring。现在让我们把这件事留在这里。

我可以创建连接并成功地查询数据库。 但我得到这个错误

像

Some resources failed to close properly while closing [email protected]

和

WARNING: Failed to destroy resource: [email protected]

我得到的错误是相当重复的。 他们都是这样的

我完全不知道为什么你看到的例外，但他们是例外情况C3P0正在清理语句应该已经被用户关闭，但并非如此。解决问题的一种方法（可以解决问题或给出有关问题发生位置的更清晰的信息）将确保您的客户端应用程序在使用它们后立即关闭语句。 c3p0在签入Connections时（或者在从池中删除PooledConnection时）会小心地为您清理未关闭的语句，但是如果发生异常，它们将在资源调配过程中作为异常报告，清理，即关闭（）期间。这就是你所看到的。

在PooledConnection被破坏的时候，如何/为什么还有未缓存的语句被关闭，这有点神秘。池在检出时不应尝试关闭（）PooledConnection，并且如果它已签入，则应在检入时清除语句。我将在记录器com.mchange.v2.c3p0.impl.NewPooledConnection上添加更多的日志记录（在FINER/DEBUG级别）到下一个预先发布的c3p0，这可能有助于跟踪这个问题。如果你有机会，请确认一下。
