无法打开 JDBC 交易连接
[英]Could not open JDBC Connection for transaction
问题描述
I would like to report a configuration problem that seems strange to me.
我想报告一个我觉得很奇怪的配置问题。 Here's the application context configuration file I'm using这是我正在使用的应用程序上下文配置文件

But when run the converting action, i have this error:但是当运行转换操作时，我有这个错误：
Problems with processing file /***.zip org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction;
Can anyone explain me what is the problem?谁能解释我有什么问题？ What should i do to fix this?我应该怎么做才能解决这个问题？
Thank you谢谢

I had to use SingleConnectionDataSource in a web application using SpringBoot.我不得不在使用 SpringBoot 的 web 应用程序中使用 SingleConnectionDataSource。 We were also using an ORM package for all db transactions and I had this same issue even with suppressClose configured to true.我们还对所有数据库事务使用了 ORM package，即使将 suppressClose 配置为 true，我也遇到了同样的问题。 It works fine during the first login, but when the connection is left idle for a long time, then the below error occurs.第一次登录时它工作正常，但是当连接长时间处于空闲状态时，就会出现以下错误。
The error was错误是
java.sql.SQLException: Connection was closed in SingleConnectionDataSource. Check that user code checks shouldClose() before closing Connections, or set 'suppressClose' to 'true'
at org.springframework.jdbc.datasource.SingleConnectionDataSource.getConnection(SingleConnectionDataSource.java:167)
Finally configuring the data source as a session scoped object resolved it.最后将数据源配置为 session 范围内的 object 解决了它。 It was a singleton before, re-configuring it to session scope resolved the issue.之前是 singleton，将其重新配置为 session scope 解决了该问题。
<bean id="dataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource" scope="session">
