1.command +, open preferences

2. Editor-> File and Code Templates

Scheme Select Default

When Includes- > File Header is selected in the tab, an editable box appears on the right, plus the following code:

# set ($str = "") # set ($stringClass=$str.getClass ()) # set ($localeClass=$stringClass.forName ("java.util.Locale")) # set ($date=$stringClass.forName ("java.util.Date"). NewInstance ()) # set ($locale=$localeClass.getConstructor ($stringClass) .newInstance ("zh_CN")) # set ($dateFormat=$stringClass.forName ("java.text.SimpleDateFormat"). GetConstructor ($stringClass, $localeClass) .newInstance ("yyyy/MM/dd ah:mm") $locale) # set ($fdate=$dateFormat.format ($date)) / * * description * * @ author xxxx * @ Date ${fdate} * /

A lot of the above code is to format the time. If you don't want to set it, you can add the following code:

/ * description * * @ author ${user} * @ Date ${date} ${time} * /

The effect is as follows:

/ * textbook series controller * @ author xxxx * @ date 2019-08-02 PM3:44 * /
