joda-time 的简单使用

1. 依赖maven：

<dependency>    <groupId>joda-time</groupId>    <artifactId>joda-time</artifactId>    <version>2.9.5</version> </dependency>

2. 测试用例：

public class DateFormat { public static Date stringToDate(String dateStr){ DateTimeFormatter format = DateTimeFormat .forPattern("yyyy-MM-dd HH:mm:ss");     //时间解析     // DateTime dateTime = DateTime.parse("2012-12-21 23:22:45", format); DateTime dateTime = DateTime.parse(dateStr, format); return dateTime.toDate(); } public static String dateTimeToString(Date date){ DateTime dateTime = new DateTime(date);  return dateTime.toString("yyyy-MM-dd HH:mm:ss");  } public static void main(String[] args) { String ss = dateTimeToString(new Date()); System.out.println(ss); Date date = stringToDate(ss); System.out.println(date); } }
