我们使用 maven spring-boot 开发了一个应用程序。

当我们使用 NetDeans IDE 运行项目时，一切正常。但是当我们构建它并从 java -jar 命令运行它时，它似乎工作并且不进行数据库更新。另一方面，它可以从数据库中读取。

我们在Jpa 存储库中使用@Transactional注释。当我们将记录器设置为 ALL 级别时，我们可以看到调试日志和构建日志之间的差异。Debug 正在使用org.springframework.orm.jpa.JpaTransactionManager处理事务，但 build 不是。构建使用org.springframework.jdbc.datasource.DataSourceTransactionManager

正如您在下面看到的，日志有一些不同的

我无法放置所有日志输出，但我认为这些小部分可以提供一些方面。知道为什么会发生这种情况吗？

我的事务服务方法：

@Transactional("transactionManager")
public ScheduledTasksLog updateScheduledTasks(ScheduledTasksLog scheduledTasksLog) {
    return scheduledTasksLogRepository.save(scheduledTasksLog);
}

@Transactional("transactionManager")
public ScheduledTasksLog getScheduledTasksLogByTaskName(String taskName) {
    return scheduledTasksLogRepository.findByTaskName(taskName);
}

我的实体存储库：

@Repository
public interface ScheduledTasksLogRepository  extends 
JpaRepository<ScheduledTasksLog, Integer> {
ScheduledTasksLog findByTaskName(String taskName);

}

我的 appsetting.properties：

我调用事务服务方法的计划任务：

@EnableScheduling
public class ScheduledTasks {



@Autowired

        ScheduledTasksLog scheduledTasksLog = testService.getScheduledTasksLogByTaskName("testtask");
        long interval = 0;
        if (scheduledTasksLog != null) {
            interval = TimeUnit.SECONDS.convert(Math.abs(new Date().getTime() - scheduledTasksLog.getLastRunDate().getTime()), TimeUnit.MILLISECONDS);
            interval += 3;
            scheduledTasksLog.setLastRunDate(new Timestamp(new Date().getTime()));
        } else {
            interval = 180;
            scheduledTasksLog = new ScheduledTasksLog();
            scheduledTasksLog.setTaskName("testtask");
            scheduledTasksLog.setLastRunDate(new Timestamp(new Date().getTime()));
        }

        testService.updateScheduledTasks(scheduledTasksLog);

    } catch (Exception e) {
        logger.info(e.getMessage());
    }
}
}

我们在 debug 和 java -jar 命令中使用相同的 application.properties 文件。JpaRepository 自己处理事务。我们不回滚或提交。我们如何手动提交？

经过几天尝试不同的解决方案，我终于找到了解决方案。

这种情况的原因是我们使用了 Spring Batch，它连接了一个名为“transactionManager”的 jdbc 事务管理器。我们的 jpa 存储库实体无法在其中持久化。所以我们不能添加或更新数据库。

解决方案是我们将我们的主要事务管理器命名为“primaryTransactionManager”并在我们的服务中使用它。我们还在spring批处理步骤配置中使用了它。一切都按预期工作。

TLDR：JPA 实体不适用于 DataSourceTransactionManager。

I noticed below the log entry from the working one.

[TRACE] 2019-12-20 10:50:32,459 org.hibernate.resource.jdbc.internal.AbstractLogicalConnectionImplementor begin - Transaction begun via JDBC Connection.setAutoCommit(false)

I noticed below the log entry from the not working one.

[DEBUG] 2019-12-20 10:45:27,177 org.springframework.jdbc.datasource.DataSourceTransactionManager doBegin - Switching JDBC Connection [HikariProxyConnection@32188486 wrapping com.mysql.cj.jdbc.ConnectionImpl@1dc5318] to manual commit

So after comparing these two, I think the probable possible solutions to your problem are listed below.

  1. Use <property name="hibernate.connection.autocommit" value="true" /> in the persistence.xml
    (Use this link and this link for more information)
  2. Use this spring.datasource.auto-commit=false in application.properties and commit it from your code.
    (Here is the answer to you why! I wonder you must be having one!)
    Setting autoCommit to false is the right thing to do.
    All RDBMS that I know of commit the transaction at the end unless explicitly rolled back. Do you see a different behavior? If you suspect something is wrong, one option is to turn on logging in the database server, where you would be able to see the commit request.
