dateconvert.java

一个Struts的小例题,通过发放令牌实现避免用户重复提交表单

package com.accp.web.action;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.apache.commons.beanutils.Converter;

public class DateConvert implements Converter {

	public Object convert(Class arg0, Object arg1) {
		if (arg1 == null) {
			return arg1;
		}
		if (arg1 instanceof Date) {
			return arg1;
		}
	     SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd") ;
	     try {
			return sdf.parse((String)arg1) ;
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} 

		return null ;
	}
