import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyClass { private static final Log log = LogFactory.getLog(MyClass.class); public void myMethod() { log.debug("Debug message"); log.info("Info message"); log.warn("Warning message"); log.error("Error message"); } }
import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyOtherClass { private static final Log log = LogFactory.getLog("myLogger"); public void myOtherMethod() { log.debug("Debug message"); log.info("Info message"); log.warn("Warning message"); log.error("Error message"); } }This code demonstrates how to create a logger instance with a custom name ("myLogger") using the LogFactory.getLog() method. The logger instance can then be used to log messages at different severity levels. Overall, the org.apache.commons.logging LogFactory interface is part of the Apache Commons Logging library, which is a Java package library that provides a simple logging interface that can be used with different logging implementations (such as Log4j, Java Logging API, or Simple Logging Facade for Java).
