java 我收到不支持的操作异常：将实体变量设置为其他实体的对象列表并保存到数据库时为null

使用setRoles设置User类中roles变量的值时更新内部的（）方法（）方法，我得到了UnsupportedOperationException: null，它只发生在setRoles中（）方法（因此注解toooooo）.在UserViewModel类的字段"roles"中，我传递了String，然后使用GetRole userService类的（）方法转换为Role对象，用该对象创建一个单例列表（Role对象），然后将其传递给setRoles（）方法。我不明白问题出在哪里，这里的哪个值为null？如何修复它？

问题在于您使用了Collection.singletonList，这是一个固定大小的列表（您可以替换位置0中的项，但不能添加或删除项），并且根据堆栈跟踪，Hibernate调用List.clear()，对于这种类型的列表，List.clear()抛出UnsupportedOperationException（因为清除尝试删除列表中的项，这是不允许的）。
您需要使用完全可修改的列表，如ArrayList，而不是Collections.singletonList。
或者，正如Andrey B. Panfilov在评论中所建议的那样：
从Hibernate和Java的Angular 来看，定义集合的默认值（即private List<Role> roles = new ArraysList<>;），然后将关联对象添加到集合中，而不是替换整个集合，这样更可靠
