spring 调度程序和 spring 批处理项目编写器的事务问题
Transactions issues with spring scheduler & spring batch item writer
我正在尝试使用 @Scheduled 注释 运行 一个 spring 批处理作业，如下所示：
@Scheduled(cron = "* * * * * ?")
public void launchMessageDigestMailing() throws JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException {
jobLauncher.run(messagesDigestMailingJob, new JobParametersBuilder().addDate("execution_date", new Date()).toJobParameters());
}
我收到以下错误：
javax.persistence.TransactionRequiredException: Executing an update/delete query
但是，当我从 spring mvc 控制器启动作业时，不会发生此错误，如下所示：
@GetMapping("/messageDigestMailing")
public void launchMessageDigestMailing() throws JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException {
jobLauncher.run(messagesDigestMailingJob, new JobParametersBuilder().addDate("execution_date", new Date()).toJobParameters());
}
我了解 Spring 批量管理交易并且不需要 @Transactional / @EnableTransactionManagement。为什么会出现上述异常？
我在网上找到的所有示例都使用 ResourcelessTransactionManager（请参阅 https://www.mkyong.com/spring-batch/spring-batch-and-spring-taskscheduler-example），但我确实需要将我的作业执行持久保存到数据库中。
有人可以帮忙吗？

编辑 3：这是我的 reader 配置：
@Bean
@StepScope
public static ItemReader<UserAccount> jpaPagingItemReader(EntityManagerFactory entityManagerFactory) {
final JpaPagingItemReader<UserAccount> reader = new JpaPagingItemReader<>();
reader.setEntityManagerFactory(entityManagerFactory);
reader.setQueryString("SELECT ua FROM UserAccount ua JOIN FETCH ua.receivedMessages msg " +
"WHERE msg.notificationSent = false AND msg.messageRead = false AND ua.enabled = true AND ua.emailNotification = true");
return reader;
}
我没有在我的批处理编写器中使用 JPA，所以我不确定是什么导致了它，但有两个指针，
1.Do 你真的需要调度程序中的这个 cron 表达式吗？
* * * * * ?
这就像告诉 - 一直启动新的作业实例，没有任何中断，或者我错过了什么？
我认为，您应该尝试在启动之间引入一些时间间隔，并相应地更改您的 cron 表达式。
2.There 是关于 SO 的问题，例如 this，正如第一个答案中指出的那样，容器管理事务和应用程序管理事务可能存在冲突。我想，你也是 运行 你在某个容器中的工作。尝试将编写器代码的相关部分抛出异常。
按照 Michael Minella 关于检查已配置 bean（/beans 端点）的建议，我注意到名为 transactionManager 的已配置和声明的事务管理器不是 JpaTransactionManager 类型。见下文：

"scope": "singleton",
"type": "com.sun.proxy.$Proxy121",
"resource": "class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]",

所以我配置了一个JpaTransactionManager如下：
@Configuration
public class TransactionManagerConfiguration {
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory);
return transactionManager;
