类 LoggingApplicationListener

  • 所有已实现的接口:
    EventListener, org.springframework.context.ApplicationListener<org.springframework.context.ApplicationEvent>, org.springframework.context.event.GenericApplicationListener, org.springframework.core.Ordered
    public class LoggingApplicationListener
extends Object
implements org.springframework.context.event.GenericApplicationListener
    An ApplicationListener that configures the LoggingSystem. If the environment contains a logging.config property it will be used to bootstrap the logging system, otherwise a default configuration is used. Regardless, logging levels will be customized if the environment contains logging.level.* entries and logging groups can be defined with logging.group.

    Debug and trace logging for Spring, Tomcat, Jetty and Hibernate will be enabled when the environment contains debug or trace properties that aren't set to "false" (i.e. if you start your application using java -jar myapp.jar [--debug | --trace]). If you prefer to ignore these properties you can set parseArgs to false.

    By default, log output is only written to the console. If a log file is required the logging.path and logging.file properties can be used.

    Some system properties may be set as side effects, and these can be useful if the logging configuration supports placeholders (i.e. log4j or logback):

    • LOG_FILE is set to the value of path of the log file that should be written (if any).
    • PID is set to the value of the current process ID if it can be determined.
