Java处理特殊时间格式 2021-06-26T12:11:52.000+0000 转为常见格式 2021-06-26 12:11:52

1. 定义常量类

public class ExchangeConstants {
    public static final String FORMAT = "yyyy-MM-dd HH:mm:ss";
    public static final String FORMAT_T = "yyyy-MM-dd'T'HH:mm:ss";
    public static final String FORMAT_Z = "EEE MMM dd HH:mm:ss Z yyyy";
}

2. 代码逻辑实现
   • 这里碰到的 2021-06-26T12:11:52.000+0000 这种格式, 是从数据库取出来时, 数据库对应datetime类型。

import com.example.demo.Demo.util.ExchangeConstants;

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;

public class Test02 {
    public static void main(String[] args) {
        //MySQL识别的日期格式
        String date = "2021-06-26T12:11:52.000+0000";

        System.out.println(dealDateFormat(date));
        //输出: 2021-06-26 12:11:52
    }

    /**
     * 处理时间格式 2021-06-26T12:11:52.000+0000 为 yyyy-MM-dd HH:mm:ss
     */
    static String dealDateFormat(String oldDate) {
        Date date1 = null;
        DateFormat df2 = null;
        try {
            DateFormat df = new SimpleDateFormat(ExchangeConstants.FORMAT_T);
            Date date = df.parse(oldDate);
            SimpleDateFormat df1 = new SimpleDateFormat(ExchangeConstants.FORMAT_Z, Locale.UK);
            date1 = df1.parse(date.toString());
            df2 = new SimpleDateFormat(ExchangeConstants.FORMAT);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return df2.format(date1);
    }
}
