#%p: The priority of output log information, namely DEBUG, INFO, WARN, ERROR, FATAL.
#%d: The date or time of the output log time point. The default format is ISO8601. You can also specify the format after it, such as: %d{yyyy/MM/dd HH:mm:ss,SSS}.
#%r: The number of milliseconds it took to output the log information since the application was started.
#%t: Output the thread name that generated the log event.
#%l: Output the location of the log event, which is equivalent to the combination of %c.%M (%F:%L), including the full class name, method, file name, and the number of lines in the code. For example: test.TestLog4j.main(TestLog4j.java:10).
#%c: The category to which the output log information belongs, usually the full name of the category.
#%M: Output the name of the method that generates log information.
#%F: The name of the file where the output log message was generated.
#%L::: The line number in the output code.
#%m::: Output the specific log information specified in the code.
#%n: Output a carriage return line feed, "rn" for Windows platforms and "n" for Unix platforms.
#%x: Output the NDC (Nested Diagnostic Environment) associated with the current thread, especially for multi-client multi-threaded applications like java servlets.
#%%: Output a "%" character.
#In addition, you can also add modifiers between % and the format character to control its minimum length, maximum length, and text alignment. Such as:
#1) c: Specify the name of the output category. The minimum length is 20. If the length of the category name is less than 20, it will be right-aligned by default.
#2)%-20c: "-" sign indicates left alignment.
#3)%.30c: Specify the name of the output category. The maximum length is 30. If the length of the category name is greater than 30, the extra characters on the left will be truncated, but if it is less than 30, no spaces will be added.
