Java Weblogic连接池Exhaused

我们在应用程序中使用weblogic连接池。我们正在使用hibernate访问数据库。现在，当我们尝试从weblogic数据源获取连接时，它会引发安全异常。因此，我们需要在hibernate.properties中放置weblogic凭据，如下所示

hibernate.connection.username=weblogic
hibernate.connection.password=weblogic1 

现在这一切都很好，但当我把加密密码放在hibernate.properties中，然后我们在开始时解密密码，设置为hibernate配置，如下所示

String password = config.getProperty("hibernate.connection.password"); 
if (password != null) { 
     password = Cryptography.decryptIfNeeded(password); 
     config.setProperty("hibernate.connection.password",password); 
}

一切正常，但一到两个小时后，我们开始关注weblogic连接池耗尽的问题。现在，当我删除上面的密码解密代码并将纯文本密码放入hibernate道具中时，一切正常，没有连接池耗尽，即使我们让env运行了几天也会出现问题

我无法找出问题的原因。 在我们的应用程序中，我们有一个轮询器，它在10秒后继续轮询db表，该轮询器开始获取连接池exahsuted error
