Abstract: This article briefly describes how to use log4j/jdk5 log and Apache universal log package commmons-logging to output logs.

Commons-logging.properties file configuration information
# Org. Apache. commons. Logging. log = org. Apache. commons. Logging. impl. simplelog
# Must be one of ("trace", "debug", "info", "Warn", "error", or "Fatal ").
# Use log4j as the output medium
Org. Apache. commons. Logging. log = org. Apache. commons. Logging. impl. log4jcategorylog

# Jdk5 Logger
# Org. Apache. commons. Logging. log = org. Apache. commons. Logging. impl. jdk14logger

 

# Log4j. properties file configuration information. It is best to put log4j. properties in classpath.
# For example, the web-INF/classes directory or other classpath directories.
Log4j. rootlogger = error, stdout, lf5, file
