我有以下场景。我使用JPA，Spring：

@Autowired
SampleService service;

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public void PerformLogic(LogicData data) throws SIASFaultMessage
{
    SampleObject so = createSampleObject();

    try{
        .//do some logic to persist things in data
        .
        .
        persistData(data);
        .
        .
        .

        updateSampleObject(so);     
    }
    catch(Exception){
        updateSampleObject(so);     
        throw new SIASFaultMessage();
    }

}

@Transactional(propagation = Propagation.REQUIRES_NEW)
public createSampleObject()
{
    SampleObject so = new SampleObject();

    .
    .//initialize so
    .

    service.persist(so);        
    return so;
}

@Transactional(propagation = Propagation.REQUIRES_NEW)
public updateSampleObject(SampleObject so)
{               
    service.persist(so);        
    return so;
}

当一切正常时，数据可以毫无问题地保存在数据库中。（所以）将信息保存在数据库中。这不是正在发生的事情。如果抛出异常，updateSampleObject方法也会回滚，这不是我所需要的。2我需要这两个方法（***createSampleObject和updateSampleObject*）在任何时候都能被持久化，无论是否抛出异常。3我该如何实现这一点呢？
此外，如果我使用以下语句注解方法createSampleObject和updateSampleObject：

@Transactional(propagation = Propagation.NEVER)

我的想法是抛出一个异常，而我没有得到抛出的异常。2问题出在哪里？3分析日志时我看到这一行：

org.springframework.orm.jpa.JpaTransactionManager  ==> Creating new transaction with name [com.test.PerformLogic]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT....

这意味着创建了此事务，但没有看到其他事务的任何提示。
这是我的Spring配置文件中有关事务的部分
