jsp页面使用C标签对时间日期进行判断

1. <c:set var="nowDate" value="<%=System.currentTimeMillis()%>"></c:set>  
2.           <c:choose>  
3.           <c:when test="${nowDate-eduDetail.endTime.getTime() > 0}">  
4.           <td class="am-hide-sm-only">已结束</td>   
5.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.beginTime " /></td>   
6.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.endTime " /></td>  
7.                         
8.           </c:when>  
9.           <c:when test="${nowDate-eduDetail.beginTime.getTime() < 0}">  
10.           <td class="am-hide-sm-only">未开始</td>  
11.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.beginTime " /></td>   
12.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.endTime " /></td>   
13.           <td>  
14.                
15.           </c:when>  
16.           <c:otherwise>  
17.           <td class="am-hide-sm-only">进行中</td>  
18.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.beginTime " /></td>   
19.           <td class="am-hide-sm-only"><s:property value="#attr.eduDetail.endTime " /></td>  
20.           <td>  
21.                         
22.           </c:otherwise>  
23.           </c:choose>  

注意，如果不加上 "  .getTime()"则会报错java.lang.IllegalArgumentException: Cannot convert 16-4-30 上午12:00 of type class java.sql.Date to Number
