在JSP中使用Struts 2比较日期

在上面，您试图将字符串与引起问题的日期对象进行比较。我建议您编写一个帮助程序类以比较日期并利用OGNL静态方法访问的优势。OGNLBasics-
访问静态属性

    <s:set var="currentDate" value="%{new java.util.Date()}"/>    <s:set var="futureDate" value="%{new java.util.Date()}"/>    <s:property value="{#currentDate}"/>    <s:property value="{#futureDate}"/>    <s:if test="%{@com.mycompany.temp.strtus2.example.HelloWorld@compareDate(#currentDate, #futureDate)}">        <div>Do your stuff</div>    </s:if>    <s:else>        <div>else condition</div>    </s:else>

实用类

public static boolean compareDate(Date currentDate, Date futureDate) {    boolean flag = false;    if (removeTime(currentDate).equals(removeTime(futureDate))) {        flag = true;    }     return flag;}public static Date removeTime(Date date) {    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.set(Calendar.HOUR_OF_DAY, 0);    cal.set(Calendar.MINUTE, 0);    cal.set(Calendar.SECOND, 0);    cal.set(Calendar.MILLISECOND, 0);    return cal.getTime();}
