1.Date轉(zhuǎn)String

1.1Date->String

        //date->String
        Date date = new Date();
        String format = dateFormat.format(date);
        System.out.println("format = " + format);

1.2String->Date

        //yyyy-MM-dd HH:mm:ss
        //SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String time = "2023-04-03";
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        //1.string->date
        Date parse = dateFormat.parse(time);
        System.out.println("parse = " + parse);

2.Date轉(zhuǎn)TimeStamp

2.1Date->TimeStamp

        //Date->TimeStamp
        Date date = new Date();
        long time = date.getTime();
        Timestamp createTime = new Timestamp(time);
        System.out.println("createTime = " + createTime);

2.2TimeStamp->Date

        //TimeStamp->Date
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        Date timestampToDate = new Date(timestamp.getTime());
        System.out.println("timestampToDate = " + timestampToDate);

3.Date轉(zhuǎn)DateTime

DateTime使用依賴

        <dependency>
            <groupId>joda-time</groupId>
            <artifactId>joda-time</artifactId>
            <version>2.9.1</version>
        </dependency>

3.1Date->DateTime

方法1：

        //method1
        Date date = new Date();
        DateTime dateTime1 = new DateTime(date);

方法2：文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-606451.html

         //method2
        Date date = new Date();
        String dateTimeString = new DateTime(date).toString("yyyy-MM-dd");
        DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd");
        DateTime time = dateTimeFormatter.parseDateTime(dateTimeString);
        System.out.println("Date->DateTime: " + time);

3.2DateTime->Date

        //DateTime->Date
        DateTime dateTime = new DateTime();
        Date dateToDateTime = dateTime.toDate();
        System.out.println("DateTime->Date" + dateToDateTime);

4.String轉(zhuǎn)DateTime

        //String->DateTime
        String dateTimeString = "2023-04-08";
        DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd");
        DateTime time = dateTimeFormatter.parseDateTime(dateTimeString);
        System.out.println("String->DateTime: " + time);
        //DateTime->String
        DateTime dt=new DateTime();
        String format="YYYY-MM-dd HH-mm-ss";
        String str= dt.toString(format);
        System.out.println("DateTime->String = " + str);

5.String與TimeStamp互轉(zhuǎn)

         String timeStr = "2023-04-06 10:30:40";
        //String -> Timestamp
        Timestamp time = Timestamp.valueOf(timeStr);
        //Timestamp -> String
        String strn = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(time);
        System.out.println("Timestamp time = " + time);
        System.out.println("strn = " + strn);
