3.用日期生成檔名工具類
package ****;//換成實際專案中的包

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

/**

• 檔名生成工具類(根據日期生成檔名)
  */
  public class FileNameGenerate {

  private String valueOfString(String str, int len) {
  StringBuffer sb = new StringBuffer();
  for (int i = 0; i < len - str.length(); i++) {
  sb.append(“0”);
  }
  return (sb.length() == 0) ? (str) : (sb.toString() + str);
  }

  public String getDateFormat(){
  SimpleDateFormat df = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);
  return df.format(new Date());
  }

  public Date getDateFormat(String time){
  SimpleDateFormat df = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);
  try {
  return df.parse(time);
  } catch (ParseException e) {
  e.printStackTrace();
  }
  return null;
  }

  private String getFileNameGenerate(Calendar calendar) {
  StringBuffer sb = new StringBuffer();
  sb.append(String.valueOf(calendar.get(Calendar.YEAR)))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.MONTH) + 1),2))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.DAY_OF_MONTH)),2))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.HOUR_OF_DAY)),2))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.MINUTE)),2))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.SECOND)),2))
  .append(this.valueOfString(String.valueOf(calendar.get(Calendar.MILLISECOND)),3));
  return sb.toString();
  }

  public String getFileNameGenerate(String time){
  Calendar calendar = new GregorianCalendar();
  calendar.setTime(this.getDateFormat(time));
  return this.getFileNameGenerate(calendar);
  }

  public String getFileNameGenerate(){
  Calendar calendar = new GregorianCalendar();
  return this.getFileNameGenerate(calendar);
  }

  public static void main(String[] args) {
  FileNameGenerate fileName = new FileNameGenerate();
  System.out.println(fileName.getFileNameGenerate());
  System.out.println(fileName.getFileNameGenerate(“2015-4-30 8:51:52”));
  }
