我正在为一个电子商务网站项目编写一个SpringBoot应用程序，我在其中创建一个表单来更改用户帐户的当前密码。提交表单时出现以下两个错误。
An error happened during template parsing (template: "class path resource [templates/myprofile.html]")
Caused by: org.attoparser.ParseException: Exception evaluating SpringEL expression: "user.id" (template: "myprofile" - line 110, col 68)
Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "user.id" (template: "myprofile" - line 110, col 68)
Property or field 'id' cannot be found on object of type 'java.lang.Boolean' - maybe not public or not valid?

答案 0 :(得分：0)
您在这里尝试访问id模型属性的user字段：
<input type="hidden" name="id" th:value="${user.id}" />
此处将user模型属性设置为true，因此它的类型为boolean：
model.addAttribute("user", true);
由于类型为boolean的变量没有名为id的字段，尝试访问它会产生您看到的错误。我认为这是因为您不想将该模型属性设置为true（也许您想将其设置为currentUser？），或者您不想将id字段设置为要访问的对象属于另一个模型属性。
