< fmt:parseDate 
      var ="date"  
     parseLocale ="zh_CN"  
     value ="${param.year}-${param.month}-${param.day}" >
   
</ fmt:parseDate >

< fmt:formatDate  value ="${date}"  dateStyle ="full" />



</ body >
</ html >

 

提交后，显示结果诸如1930年11月1日 星期六

 

如果日期输入是en_US格式，也就是做以下改动

<select name="month">
<option value="Jan">January</option>
<option value="Feb">February</option>
<option value="Mar">March</option>
<option value="Apr">April</option>
<option value="May">May</option>
<option value="Jun">June</option>
<option value="Jul">July</option>
<option value="Aug">August</option>
<option value="Sep">September</option>
<option value="Oct">October</option>
<option value="Nov">November</option>
<option value="Dec">December</option>
</select>

则日期处理页面也要做想应改动

<fmt:parseDate
     var="date"
     parseLocale="en_US"
     value="${param.month} ${param.day}, ${param.year}"> 

注意逗号后有一个空格，因为英文的日期格式为"May 25, 1997"
</fmt:parseDate>
