对于这个类，我在任何地方都使用默认构造函数。例外情况很明显：role列（在表Roles中）可能不为null。给定堆栈跟踪，我假设您正在保存一个与角色有关联的用户，而这个角色有一个nullrole
字段。由于您将关联配置为级联，因此也会保存该角色，并且由于该角色具有null角色
，因此插入失败
编辑：新错误显示数据库中的列Users.roleId
不能为空。因此，在保存用户之前，必须为其设置一个角色。在数据库中为此列指定默认值是无用的，因为只有在insert语句中未为此列指定值时，才会使用默认值。但是Hibernate将始终指定一个值。不管怎样，默认值是个坏主意，因为Hibernate不知道它们，因此如果不刷新它们，就无法将它们包含在实体中
旁注：如果不从实体上的注释生成数据库模式，则不应指定这些注释的可空、唯一、长度属性。尤其是当它们与数据库中的实际列定义相矛盾时。当列实际上不可为空时，用nullable=true
注释列会使事情变得非常混乱。例外情况非常清楚：角色列（在表角色中）可能不为空。给定堆栈跟踪，我假设您正在保存一个与角色有关联的用户，而这个角色有一个nullrole
