JSP:访问JSP EL标记内的枚举

Question

我的java enum看起来像这样:

public enum EmailType { HOME, WORK, MOBILE, CUSTOMER_SERVICE, OTHER }

在JSP中,我试图做下面的事情,这是行不通的.

<c:choose>
          <c:when test="${email.type == EmailType.HOME}">(Home)</c:when>
          <c:when test="${email.type == EmailType.WORK}">(Work)</c:when>
</c:choose>

谷歌搜索后,我发现这些链接:在JSP中的枚举.但是,我想避免在JSP中使用scriplets.如何访问EL标签内的java枚举并进行比较？请帮忙.

Answer 1

当枚举被序列化时,它变成一个字符串.所以只需使用字符串比较.

<c:choose>
          <c:when test="${email.type == 'HOME'}">(Home)</c:when>
          <c:when test="${email.type == 'WORK'}">(Work)</c:when>
</c:choose>
