SpringBoot spring boot + jpa +Scheduled transaction error

If it is called in the controller, it is normal. My service method uses @Transaction annotation What happened

I think it's a magic problem, come and save me task service dao error If I add a controller and call it in the controller, the method executes normally @RestMapping... @ResponseBody public String test(){ generateTaskService.updateStatus(1,2); } Give me some advice

@romantictravel01 This isn't the right place to ask for advice. Please use Gitter or Stack Overflow for that. Also, please be aware that Spring Boot 1.5 is no longer support. You should be looking to upgrade to 2.x as soon as you can.
