common -lang DateFormatUtils充满了好东西(如果你的类路径中有common -lang)

//Formats a date/time into a specific pattern
 DateFormatUtils.format(yourDate, "yyyy-MM-dd HH:mm:SS");

使用DateFormat#format方法将日期转换为字符串:

String pattern = "MM/dd/yyyy HH:mm:ss";

// Create an instance of SimpleDateFormat used for formatting 
// the string representation of date according to the chosen pattern
DateFormat df = new SimpleDateFormat(pattern);

// Get the today date using Calendar object.
Date today = Calendar.getInstance().getTime();        
// Using DateFormat format method we can create a string 
// representation of a date with the defined format.
String todayAsString = df.format(today);

// Print the result!
System.out.println("Today is: " + todayAsString);

单镜头;)

获取日期

String date = new SimpleDateFormat("yyyy-MM-dd",   Locale.getDefault()).format(new Date());

为了得到时间

String time = new SimpleDateFormat("hh:mm", Locale.getDefault()).format(new Date());

来获取日期和时间

String dateTime = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.getDefaut()).format(new Date());

快乐编码:)

为什么不用Joda (org.joda.time.DateTime)? 基本上就是一行代码。

Date currentDate = GregorianCalendar.getInstance().getTime();
String output = new DateTime( currentDate ).toString("yyyy-MM-dd HH:mm:ss");

// output: 2014-11-14 14:05:09

Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String s = formatter.format(date);

看起来您正在寻找SimpleDateFormat。

格式:yyyy-MM-dd kk:mm:ss
