Copy code The code is as follows:

/**
* Extension of Date, convert Date into String in specified format
* Month (M), day (d), 12 hours (h), 24 hours (H), minutes (m), seconds ( s), week (E), quarter (q) can use 1-2 placeholders
* year (y) can use 1-4 placeholders, milliseconds (S) can only use 1 placeholder symbol (is a number of 1-3 digits)
* eg:
* (new Date()).pattern("yyyy-MM-dd hh:mm:ss.S") ==> 2006- 07-02 08:09:04.423
* (new Date()).pattern("yyyy-MM-dd E HH:mm:ss") ==> 2009-03-10 Tuesday 20:09:04
* (new Date()).pattern("yyyy-MM-dd EE hh:mm:ss") ==> 2009-03-10 Tuesday 08:09:04
* (new Date( )).pattern("yyyy-MM-dd EEE hh:mm:ss") ==> 2009-03-10 Tuesday 08:09:04
* (new Date()).pattern("yyyy- M-d h:m:s.S") ==> 2006-7-2 8:9:4.18
