日期的Spring表单标记出现奇怪错误,spring,forms,jsp,Spring,Forms,Jsp,我有和相关的getter/setter 我的家庭控制器（只有一个控制器）是最后，我的观点是 @RequestMapping(value = "/validation", method = RequestMethod.GET) public String new_validation(Locale locale, Model model) { FormInputValidationTest fivt = new FormInputValidationTest(); logger

我有

和相关的getter/setter

我的家庭控制器（只有一个控制器）是

最后，我的观点是

@RequestMapping(value = "/validation", method = RequestMethod.GET)
public String new_validation(Locale locale, Model model) {
    FormInputValidationTest fivt = new FormInputValidationTest();
    logger.info("in validation for GET request");
    model.addAttribute("fivt",fivt);
    return "validation";
}

@RequestMapping(value = "/validation", method = RequestMethod.POST)
public String new_validation(@ModelAttribute("fivt") FormInputValidationTest fivt, Locale locale, Model model, HttpServletRequest req) {
    logger.info("in validation for POST request");
    logger.info("email received from user input is : {}",fivt.getEmail());
//  logger.info("dob received from user input is : {}",fivt.getDob().toString());
    logger.info("desig received from user input is : {}",fivt.getDesig());
    logger.info("doj received from user input is : {}",fivt.getDoj());
    model.addAttribute("message","successfully added");
    return new_validation(locale, model);
}

没有“dob”作为输入，它工作正常我一直在尝试查看请求头和请求体，但我仍然无法理解为什么这会给我带来一些问题。所以我添加了doj（预期日期），但声明为要测试的字符串，这似乎很好

有人能解释一下吗？特别是因为这段代码（我还没有尝试过）似乎能够处理关联模型中日期对象的输入

PS：即使我在表单标签中使用modeldattribute=“fivt”

也一样，只要提交表单，它的值都是String类型的。现在，当您编写“Date dob”时，spring试图做的是将字符串值赋给日期变量，这是不可能的。正确的方法是使用@DateTimeFormat annotation over date变量告诉spring将传入的字符串值转换为相应的日期值

请参阅post

Prabhat。。谢谢你的回复。。我已经能够在过去的工作中确保日期暂时是yyyy/mm/dd格式。。

    model.addAttribute("fivt",fivt);
    return "validation";
}
