最近，随着我的生产应用程序的用户数量不断增加，我开始收到以下错误(数千个):
org.hibernate.exception.GenericJDBCException: could not prepare statement Problem Id:com.microsoft.sqlserver.jdbc.SQLServerException at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDriverError
The connection is closed. Problem Id:com.microsoft.sqlserver.jdbc.SQLServerException at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDriverError

我想知道这是否与 c3p0 连接池有关。
如果信息是从 app-config 文件中获取的，而不是从 hibernate.properties 文件中获取的，我不是 100%。
我也附上了这两个文件，您可以在下面看到内嵌的相关信息:
应用程序配置.xml:

<!-- Pool properties --

hibernate.c3p0.max_size=20
hibernate.c3p0.max_statements=0

自从开始发现这些错误以来，我没有更改应用程序或服务器中的任何内容。
任何解决此问题的帮助将不胜感激。
最佳答案
您的 hibernate.properties 文件正在设置 MySql 驱动程序，而您的 app-config.xml 正在设置 SQL Server 驱动程序。由于错误消息提到了 SQL Server，我猜测您的 app-config.xml 就是所使用的。 (您的 hibernate.properties 还设置了 hibernate.hbm2ddl.auto=update ，它永远不应该在生产中使用)。
app-config.xml 将 testConnectionOnCheckin 设置为 true。这意味着连接返回到池中时会得到验证。它还将 idleConnectionTestPeriod 设置为 30，这意味着每 30 秒验证一次空闲连接。这使得问题不太可能(但并非不可能)是数据库在连接池时关闭连接。
您可以尝试将 testConnectionOnCheckIn 替换为 testConnectionOnCheckout。这肯定会解决数据库关闭连接的任何问题。如果这不起作用，那么问题是程序主动关闭连接，然后尝试再次使用它。
关于java - 获取 SQLServerException makeFromDriverError 消息 'could not prepare statement' 和 'The connection is closed'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55881526/
