Interface Logger

public interface Logger
This is the central interface in the log4j package. Most logging operations, except configuration, are done through this interface.

The canonical way to obtain a Logger for a class is through LogManager.getLogger(). Typically, each class gets its own Logger named after its fully qualified class name (the default Logger name when obtained through the LogManager.getLogger() method). Thus, the simplest way to use this would be like so:

 public class MyClass {
     private static final Logger LOGGER = LogManager.getLogger();
     // ...
 }
 

For ease of filtering, searching, sorting, etc., it is generally a good idea to create Loggers for each class rather than sharing Loggers. Instead, Markers should be used for shared, filterable identification.

For service provider implementations, it is recommended to extend the AbstractLogger class rather than implementing this interface directly.

Since 2.4, methods have been added to the Logger interface to support lambda expressions. The new methods allow client code to lazily log messages without explicitly checking if the requested log level is enabled. For example, previously one would write:
 // pre-Java 8 style optimization: explicitly check the log level
 // to make sure the expensiveOperation() method is only called if necessary
 if (logger.isTraceEnabled()) {
     logger.trace("Some long-running operation returned {}", expensiveOperation());
 }
 

With Java 8, the same effect can be achieved with a lambda expression:

 // Java-8 style optimization: no need to explicitly check the log level:
 // the lambda expression is not evaluated if the TRACE level is not enabled
 logger.trace("Some long-running operation returned {}", () -> expensiveOperation());
 

Note that although MessageSupplier is provided, using Supplier<Message> works just the same. MessageSupplier was deprecated in 2.6 and un-deprecated in 2.8.1. Anonymous class usage of these APIs should prefer using Supplier instead.

  • Method Details

    • catching

      void catching(Level level, Throwable throwable)
      Logs a Throwable that has been caught to a specific logging level.
      Parameters:
      level - The logging Level.
      throwable - the Throwable.
    • catching

      void catching(Throwable throwable)
      Logs a Throwable that has been caught at the ERROR level. Normally, one may wish to provide additional information with an exception while logging it; in these cases, one would not use this method. In other cases where simply logging the fact that an exception was swallowed somewhere (e.g., at the top of the stack trace in a main() method), this method is ideal for it.
      Parameters:
      throwable - the Throwable.
    • debug

      void debug(Marker marker, Message message)
      Logs a message with the specific Marker at the DEBUG level.
      Parameters:
      marker - the marker data specific to this log statement
      message - the message string to be logged

    • debug

      void debug(Marker marker, MessageSupplier messageSupplier)

    • entry

      @Deprecated void entry()
      Deprecated.
      Use traceEntry() instead which performs the same function.
      Logs entry to a method. Used when the method in question has no parameters or when the parameters should not be logged.
    • entry

      @Deprecated void entry(Object... params)
      Deprecated.
      Use traceEntry(String, Object...) instead which performs the same function.
      Logs entry to a method along with its parameters (consider using one of the traceEntry(...) methods instead.)

      For example:

       public void doSomething(String foo, int bar) {
           LOGGER.entry(foo, bar);
           // do something
       }
       

      The use of methods such as this are more effective when combined with aspect-oriented programming or other bytecode manipulation tools. It can be rather tedious (and messy) to use this type of method manually.

      Parameters:
      params - The parameters to the method.

      Avoid passing a ReusableMessage to this method (therefore, also avoid passing messages created by calling logger.getMessageFactory().newMessage("some message")): Log4j will replace such messages with an immutable message to prevent situations where the reused message instance is modified by subsequent calls to the logger before the returned EntryMessage is fully processed.

      Parameters:
      message - The message. Avoid specifying a ReusableMessage, use immutable messages instead.
      Returns:
      the built message
