Can Log4j 1.2 What's the difference between RollingFileAppender and FileAppender?

问题

How do we know which is the right Appender to use between RollingFileAppender and FileAppender?

回答1:

You may want to read the Apache Log4j 1.2.17 API:

• org.apache.log4j.FileAppender

  FileAppender appends log events to a file.

• org.apache.log4j.RollingFileAppender

  RollingFileAppender extends FileAppender to backup the log files when they reach a certain size.
