JSP显示当前系统时间的四种方式：
第一种java内置时间类实例化对象：
1 2 3 4 5 | <base href="<%=basePath%>" rel="external nofollow"><title>My JSP 'time4.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"> |
第二种方式使用JSP内置USEBEAN实例化时间类：
1 2 3 4 5 6 7 | <base href="<%=basePath%>" rel="external nofollow"><title>显示系统时间方法一：</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><usebean id="time" class="java.util.Date"></usebean> 现在时间： |
第三种方式使用JSP USEBEAN type与beanName配对使用：
1 2 3 4 5 6 7 | <base href="<%=basePath%>" rel="external nofollow"><title>My JSP 'time2-useBean-type-beanName.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><usebean id="time" type="java.io.Serializable" beanname="java.util.Date"></usebean> 现在时间： |
第四种方式使用JSP setproperty设置属性：
1 2 3 4 5 6 7 8 | <base href="<%=basePath%>" rel="external nofollow"><title>My JSP 'time3-setproperty.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page">jsp:setproperty 实例<hr><usebean id="time" class="java.util.Date"><setproperty name="time" property="hours" param="hh"></setproperty><setproperty name="time" property="minutes" param="mm"></setproperty><setproperty name="time" property="seconds" param="ss"></setproperty></usebean><br>设置属性后的时间：${time} }<br> |
