springbatch集成了mvc导入接口后,事务异常,并且将服务层注入到作业中以执行事务问题。 BatchController.class
@RestController

}
JobParameters jobParameters = new JobParametersBuilder()

答案 0 :(得分:0)
似乎您有多个事务管理器。在这种情况下,您可以为Tasklet显式指定事务管理器。
<tasklet transaction-manager="transactionManager">
@EnableBatchProcessing
自动注册一个事务管理器。您只需实现BatchConfigurer
接口即可更改批处理使用的事务管理器。
