Jstl Long data conversion to date format

First, there is a web-inf under the establishment of a DATETAG.TLD

<?XML version= "1.0" encoding= "UTF-8"?>  <taglib>      <tlib-version>1.0</tlib-version>      <jsp-version>1.2</jsp-version>        <Tag>          <name>Date</name>          <Tag-class>Com.hoolai.pirates.football.util.DateTag</Tag-class>                  <body-content>Jsp</body-content>          <attribute>              <name>Value</name>              <Required>True</Required>              <Rtexprvalue>True</Rtexprvalue>          </attribute>      </Tag>  </taglib>

Second, create a new class DateTag

 PackageCom.hoolai.pirates.football.util;Importjava.io.IOException;ImportJava.text.SimpleDateFormat;ImportJava.util.Calendar;Importjavax.servlet.jsp.JspException;ImportJavax.servlet.jsp.tagext.TagSupport; Public classDateTagextendsTagSupport {Private Static Final LongSerialversionuid = -2312310581852395045l; PrivateString value; @Override Public intdoStartTag ()throwsjspexception {String VV= "" +value; LongTime =long.valueof (VV); Calendar C=calendar.getinstance ();        C.settimeinmillis (time); SimpleDateFormat DateFormat=NewSimpleDateFormat ("Yyyy-mm-dd HH:mm:ss"); String s=Dateformat.format (C.gettime ()); Try{pagecontext.getout (). write (s); } Catch(IOException e) {e.printstacktrace (); }        return Super. doStartTag (); }     Public voidSetValue (String value) { This. Value =value; }}

Third, the introduction of the JSP

<%@ taglib prefix= "lzq" uri= "/web-inf/lib/tld/datetag.tld"%>  

Iv. where to go in the page

<align= "Left"><name= "EndTime"  Type= "text"  value= "<lzq:date value="${res.endtime} "/> "class=" Input_bg "/></td>

This is passed in the servlet is a long, on the page with JSTL can be formatted as 2015-02-06 23:26:22
