我想报告一个我觉得很奇怪的配置问题。 这是我正在使用的应用程序上下文配置文件

但是当运行转换动作时,我有这个错误:
处理文件 /***.zip 的问题 org.springframework.transaction.CannotCreateTransactionException: 无法打开事务的 JDBC 连接;嵌套异常是 java.sql.SQLException:连接已关闭 单一连接数据源。检查用户代码检查 shouldClose() 在关闭连接之前,或将“suppressClose”设置为“true” 在 org.springframework.jdbc.datasource.DataSourceTransactionManager.doBegin(DataSourceTransactionManager.java:241) 在 org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:372) 在 org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:417) 在 org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction (TransactionAspectSupport.java:255) 在 org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:94) 在 org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172) 在 org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) 在 com.sun.proxy.$Proxy5.processFile(未知来源) 在 ru.rt.mnp.translator.converter.job.ConvertTask.execute(ConvertTask.java:69) 在 sun.reflect.GeneratedMethodAccessor12.invoke(未知来源) 在 sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 在 java.lang.reflect.Method.invoke(Method.java:497) 在 org.springframework.util.MethodInvoker.invoke(MethodInvoker.java:273) 在 org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean$MethodInvokingJob.executeInternal(MethodInvokingJobDetailFactoryBean.java:311) 在 org.springframework.scheduling.quartz.QuartzJobBean.execute(QuartzJobBean.java:113) 在 org.quartz.core.JobRunShell.run(JobRunShell.java:207) 在 org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:560) 引起:java.sql.SQLException:连接已关闭 单一连接数据源。检查用户代码检查 shouldClose() 在关闭连接之前,或将“suppressClose”设置为“true” 在 org.springframework.jdbc.datasource.SingleConnectionDataSource.getConnection(SingleConnectionDataSource.java:189) 在 org.springframework.jdbc.datasource.DataSourceTransactionManager.doBegin(DataSourceTransactionManager.java:203)
谁能给我解释一下这是什么问题? 我应该怎么做才能解决这个问题?
谢谢!
我不得不在使用 SpringBoot 的 Web 应用程序中使用 SingleConnectionDataSource。我们还为所有数据库事务使用了一个 ORM 包,即使将 suppressClose 配置为 true,我也遇到了同样的问题。在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。
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)
最后将数据源配置为会话范围的对象解决了它。之前是单例,重新配置到会话范围解决了这个问题。
<bean id="dataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource" scope="session">
