Why the @Transactional doesn't work in a web project which is based on SpringBoot?
问题
我使用SpringBoot完成了一个Web项目。无论我尝试多少次或多么努力，它仍然不会回滚。有人能帮助我吗？非常感谢！以下是代码部分：
// 控制器
@PostMapping(value = "/savePlan")
public R saveYearPlan(@RequestBody ProductPlanOutputMain productPlanOutputMain){
return planService.saveOrUpdatePlanBatch(productPlanOutputMain);
}
@Service
public class PlanServiceImpl implements PlanService {
@Override
public R saveOrUpdatePlanBatch(ProductPlanOutputMain productPlanOutputMain) {
return saveOrUpdateDailyPlan(productPlanOutputMain);
}
@Transactional(rollbackFor = Exception.class)
public R saveOrUpdateDailyPlan(ProductPlanOutputMain productPlanOutputMain){
// 将数据保存到数据库
productPlanOutputMainService.saveOrUpdatePlan(productPlanOutputMain);
// 测试回滚
throw new RuntimeException("发生了错误");
}
}
我已经尝试了很多次。

@Transactional 在从同一类调用的方法中不起作用。将其放入单独的服务类中。
英文:
@Transactional won't work for a method called from the same class. Put it in a separate service class.
