How do I obtain the current time in YYYY-MM-DD HH: MI: ms format in Java?

The code below gives me the current time. But that doesn’t account for milliseconds.

public static String getCurrentTimeStamp() { SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //dd/MM/yyyy Date now = new Date(); String strDate = sdfDate.format(now); return strDate; }Copy the code

I have a date in format YYYY-MM-DD HH:MM:SS (2009-09-22 16:47:08).

But I want to retrieve the current time in YYYY-MM-DD HH:MM: ss.ms (2009-09-22 16:47:08.128 milliseconds) format.

SimpleTextFormat will work fine. Here, the minimum unit of time is seconds, but how do you get milliseconds?

$\color{purple} a lot of knowledge points, really need to write out just can master!! {~}$

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
Copy the code

Answer:

Java a line

public String getCurrentTimeStamp() {
    return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(new Date());
}
Copy the code

In the style of JDK8

public String getCurrentLocalDateTimeStamp() {
    return LocalDateTime.now()
       .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));
}

Copy the code

Note that SimpleDateFormat is not thread-safe in high-concurrency scenarios. It is static and can be used to solve the problem by using ThreadLocal. The current thread holds an object. You can also use DateTimeFormatter to make this thread safe.Java string to date conversion?
