velocity怎么对日期进行格式化

velocity如何对日期进行格式化
例如，在数据库里日期格式是 2008-01-01 20:10:50
在velocity里要如何处理才可以只显示2008-01-01 

显示方式可以在velocity模板里控制的那种...不受java影响.....

[解决办法]

Java code

import java.io.StringWriter;import java.io.Writer;import java.util.Calendar;import java.util.TimeZone;import org.apache.velocity.Template;import org.apache.velocity.VelocityContext;import org.apache.velocity.app.Velocity;import org.apache.velocity.tools.generic.DateTool;public class DateToolExample {  public static void main(String[] args) throws Exception {    Velocity.init();    Template t = Velocity.getTemplate("./src/dateTool.vm");    VelocityContext ctx = new VelocityContext();    ctx.put("date", new DateTool());    Calendar aDate = Calendar.getInstance(TimeZone.getTimeZone("PST"));    aDate.set(200, 11, 25);    ctx.put("aDate", aDate);    Writer writer = new StringWriter();    t.merge(ctx, writer);    System.out.println(writer);  }}
