我已经尝试过将
cascade=CascadeType.MERGE
更改为
cascade=CascadeType.ALL
，但这似乎没有帮助

如果有人能帮我，我将不胜感激

我认为你必须拯救车队，而不是车手（尽管不确定）。还有一个惯例提示，不要这样做：
Driver-Driver=newdriver（）使用java命名约定：
Driver-Driver=new-Driver（）您未正确使用ElelementCollection。ElementCollection应仅用于可嵌入类型，而不用于实体。另外，您是否自己编写了Ensurer类，因为这样我就可以看看是否可以用Guavas
Premission
替换它。您的实际问题可能是您的团队参数被分离，如果是这种情况，您必须将其合并到当前的持久性上下文中，并且看起来您没有持久性上下文，因为在调用save之前不会创建它。
