在Spring中设置默认的DateTimeFormat注释 [英] Setting default DateTimeFormat Annotation in Spring

问题描述

我知道可以在Spring的Model类的Date属性上定义DateTimeFormat批注，但是有什么方法可以为Spring Model类中的所有Date定义默认的dateTimeFormat批注？

I know that a DateTimeFormat annotation can be defined on Date properties of a Model class in Spring but is there any way of defining a default dateTimeFormat annotation for all Dates in Spring Model classes?

@DateTimeFormat（pattern = MM / dd / YYYY）

private Date
deliveryDate;

@DateTimeFormat(pattern = "MM/dd/YYYY")
private Date deliveryDate;

这将使我免于注释每个日期字段。

It will save me from annotating each date field. It will also make it easy for me to change the application wide date format later on.

推荐答案

正如kuhajeyan所述，您可以使用活页夹，而不是在控制器上，而是在控制器建议上，它将在全球范围内应用：

As kuhajeyan mentioned, you can use binder, but not on a controller, rather on controller advice, that will apply it globally:

@ControllerAdvice
public class GlobalDateBinder {

 /* Initialize a global InitBinder for dates*/

 @InitBinder
 public void binder(WebDataBinder binder) {
  // here you can use kuhajeyan's code
 }
}
