java - 提交 Spring 表单时无法点击 Controller

Question

我正在使用 Spring 4.2.0 和 hibernate。我正在尝试向我的 Controller 提交一个包含日期字段的 jsp spring 表单。但我无法点击我的 Controller ，它引发了以下异常:

Field error in object 'loginDetails' on field 'dateOfBooking':rejected value [2018-02-09]; codes [typeMismatch.loginDetails.dateOfBooking,typeMismatch.dateOfBooking,typeMismatch.java.util.Date,typeMismatch];arguments[org.springframework.context.support.DefaultMessageSourceResolvable:codes [loginDetails.dateOfBooking,dateOfBooking]; arguments [];default message [dateOfBooking]]; default message [Failed to convertproperty value of type 'java.lang.String' to required type'java.util.Date' for property 'dateOfBooking'; nested exception isjava.lang.IllegalStateException: Cannot convert value of type[java.lang.String] to required type [java.util.Date] for property'dateOfBooking': no matching editors or conversion strategy found].

Below is my jsp code, bean and controller code.

This is my bean for table booking which includes a date field:

@DateTimeFormat(pattern="yyyy-MM-dd")
private Date dateOfBooking;

这是我的 Controller 代码，它不会无缘无故地变热:

@RequestMapping("/bookingTable")  
public ModelAndView bookingTable(@ModelAttribute("loginDetails") BookingTable bookingTable,HttpServletRequest request,ModelMap model) throws ParseException{
    HttpSession session = request.getSession();
    //Doing something here
    return new ModelAndView("bookingDetails");  
}

请帮我解决这个问题。我长期以来一直在尝试这样做。但不能。

你可以尝试向你的 Controller 添加一个@InitBinder吗？

要自定义请求参数数据绑定(bind)，我们可以在 Controller 中使用 @InitBinder 注解的方法。 https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/bind/annotation/InitBinder.html
