SpringBoot Thymeleaf序数 [英] SpringBoot Thymeleaf ordinal numbers

问题描述

我读了一些不错的帖子，例如此，其中解释了给定<$时接收序数的方法c $ c> int 。

I have read a few good posts like this one which explain the method of receiving ordinal numbers when given an int.

现在，我有一个LocalDate对象，可以使用任何 DateTimeFormat 模式。示例如下：

Now, I have a LocalDate object and I can format my dates using any of the DateTimeFormat patterns in my Thymeleaf template. Example being something like:

<strong th:text="${item.date} ? ${#temporals.format(item.date, 'dd')}"></strong>

问题：我应该怎样做？与Thymeleaf中我链接到上面的帖子类似的结果。

Question: How can I or perhaps what is the best way of achieving similar results to the post I linked to above in Thymeleaf.

我不是经验丰富的Java开发人员，所以如果您尽可能详尽地解释答案，这将对您很有帮助。

I am not an experienced Java developer so it would be very helpful if you be as thorough as you possibly can with explaining the answer.

推荐答案

在Thymeleaf模板中，您可以使用静态字段（和函数），因此您的情况如下所示：

1）与您相关的问题中的代码（我稍微修改了一下）：

Inside the Thymeleaf's template you can use static fields (and functions), so in you case it will looks like that:
1) Code from the question you related (I just modified it a little bit) :

package your.packagename;
// http://code.google.com/p/guava-libraries
import static com.google.common.base.Preconditions.*;

public class YourClass {

    public static String getDayOfMonthSuffix(String num) {
        Integer n = Integer.valueOf(num == null ? "1" : num);
        checkArgument(n >= 1 && n <= 31, "illegal day of month: " + n);
        if (n >= 11 && n <= 13) {
            return "th";
        }
        switch (n % 10) {
            case 1:  return "st";
            case 2:  return "nd";
            case 3:  return "rd";
            default: return "th";
        }
    }
}

2）在视图：

<strong th:text="${#temporals.format(item.date, 'dd') + T(your.packagename.YourClass).getDayOfMonthSuffix(#temporals.format(item.date, 'dd'))}"></strong>
