Taglib显示java.time.LocalDate格式

Question

I would like to display formatted java.time.LocalDate in my JSP. Do you know any taglib to use for this?

For java.util.Date we were using <%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %> . Does something similar for java.time.LocalDate exist?

Answer 1

Afsun's hints inspired me to create a quick solution.

1. Under /WEB-INF create directory tags .
2. Create tag file localDate.tag inside the tags directory.

3. Put bellow code into this tag file:

    <%@ tag body-content="empty" pageEncoding="UTF-8" trimDirectiveWhitespaces="true" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ attribute name="date" required="true" type="java.time.LocalDate" %> <%@ attribute name="pattern" required="false" type="java.lang.String" %> <c:if test="${empty pattern}"> <c:set var="pattern" value="MM/dd/yyyy"/> </c:if> <fmt:parseDate value="${date}" pattern="yyyy-MM-dd" var="parsedDate" type="date"/> <fmt:formatDate value="${parsedDate}" type="date" pattern="${pattern}"/> 

4. Go to the JSP file in which you want display the java.time.LocalDate .

   4.1. Add taglib directive <%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %> at the top of the file.

   4.2. Use the localDate tag as follows:

   • <tags:localDate date="${yourDateToPrint}"/>
   • <tags:localDate date="${yourDateToPrint}" pattern="${yourPatternFormat}"/>

You can do this by fmt:parseDate .Try following:

<fmt:parseDate value="${dateForParsing}" pattern="yyyy-MM-dd" var="parsedDate" type="date" />

<fmt:formatDate value="${parsedDate}" var="newParsedDate" type="date" pattern="dd.MM.yyyy" />

I hope this help you. More information
