属性或字段'；id'；在类型为'；java.lang.Boolean'；-可能不是公开的或无效的？

我正在为一个电子商务网站项目编写一个SpringBoot应用程序，我正在创建一个表单来更改用户帐户的当前密码。在提交表单时，我遇到以下两个错误

错误-1

错误-2

此处您尝试访问

用户

模型属性的

id

字段：

<input type="hidden" name="id" th:value="${user.id}" />

---

由于

boolean

类型的变量没有名为

id

的字段，因此尝试访问它时会出现错误。我假设您不想将该模型属性设置为

true

（可能您想将其设置为

currentUser

？），或者您要访问的

id

字段属于另一个模型属性。
