我使用 Spring MVC 和 Spring JPA 开发了我的第一个应用程序。使用 @Transactional 注释时出现问题。我用@Transactional 注释了我的一个服务方法,并在该方法中抛出异常,因为我希望它会被回滚,但事实并非如此。
这是我的配置文件和我的类文件内容:

在 AttributeService.java 中,在 save 方法中,您可以找到:
t = attributeRepository.save(t);
if(t.getId() > 1){
throw new Exception();
}
所以在我调用 save 之后,我立即抛出了一个异常,但是我检查了数据库,它并没有回滚。
我真的很感谢你们的帮助,谢谢!
