java时间格式

Date date = new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
SimpleDateFormat df1 = new SimpleDateFormat("yyyy-MM-dd'测试'HH:mm:ss.SSSZ");
SimpleDateFormat df2 = new SimpleDateFormat("YYYY-MM-DD'T'HH:mm:ss.sssZ");
String str = df.format(date);
String str1 = df1.format(date);
String str2 = df2.format(date);
System.out.println(str);
System.out.println(str1);
System.out.println(str2);



结果:
2020-01-16T10:57:27.901+0800
2020-01-16测试10:57:27.901+0800

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
Calendar nowTime = Calendar.getInstance();
nowTime.add(Calendar.MINUTE, 5);
String str3 = sdf.format(nowTime.getTime());
System.out.println(str3);



结果:
