Log4j. perproties Configuration

# -- Log4j. rootlogger: output the log information with the info level to the stdout and file destinations. The definitions of stdout and file can be named in the following code. Levels can be divided into off, fatal, error, warn, info, debug, and all. If off is configured, no information is displayed. If Info is configured, only info, warn is displayed, error Log information, while debug information is not displayed
Log4j. rootlogger = warn, stdout, file

### -- % M output the specified message in the code
### -- % P output priority, that is, debug, info, warn, error, fatal
### -- % R the number of milliseconds it takes to output the log information from application startup to output
### -- % C output category, usually the full name of the class
### -- % T name of the thread that outputs the log event
### -- % N output a carriage return line break. For Windows, the return value is "RN", and for UNIX, the return value is "N"
### -- % D date or time of the log output time point. The default format is iso8601. You can also specify the format after it, for example, % d {yyyy Mmm dd hh: mm: SS, SSS}, output: October 18, 2002 22:10:28, 921
### -- % L location where the log event is output, equivalent to % C. % m (% F: % L) combination, including the category name, the thread that occurs, and the number of lines in the code.
### -- % F name of the file where the log message is generated
### -- % L the row number in the output code
### -- % 5 p add 5 spaces before Priority
### -- [XXX] The content in brackets is used for display. It can be any character and is generally called the project abbreviation.
