Spring事务-防止在未检查的异常之后回滚（RuntimeException）

Question

@Service("fooService")
public class FooServiceImpl implements IFooService {

    @Transactional
    @Override
    public void doStuff(Resource res){
        authService.createResource(res, "ADMIN");
        try {
            throw new RuntimeException("SOMETHING");
        } catch (RuntimeException e) {
            e.printStackTrace();
        }
    }

    @Transactional(noRollbackFor=RuntimeException.class)
    @Override
    public void doStuff2(Resource res){
        authService.createResource(res, "ADMIN");
        throw new RuntimeException("SOMETHING");
    }

    @Transactional(noRollbackFor=RuntimeException.class)
    @Override
    public void doStuff12(Resource res){

        authService.createResource(res, "ADMIN");
        try{
            res.setName("EXISTING-RESOURCE");
            authService.createResource(res, "ADMIN");
        }catch(RuntimeException e){
            e.printStackTrace();
        }
    }

尽管捕获了RuntimeException并声明了noRollbackFor属性，但事务总是回滚。有什么解释吗？？

据我所知，一旦从事务性方法引发运行时异常并被事务拦截器拦截，该事务就被标记为仅回滚。即使此事务性方法是从另一事务性方法调用的。

这对我来说是有意义的：如果内部方法不能从异常中恢复，它就不能恢复，外部方法不应该像什么都没发生一样。

如果希望事务不回滚，则可以

null
