public final class Log4jLoggerAdapter extends MarkerIgnoringBase implements LocationAwareLogger, Serializable
A wrapper overorg.apache.log4j.Logger
in conforming to theLogger
interface.Note that the logging levels mentioned in this class refer to those defined in the
org.apache.log4j.Level
class.The TRACE level was introduced in log4j version 1.2.12. In order to avoid crashing the host application, in the case the log4j version in use predates 1.2.12, the TRACE level will be mapped as DEBUG. See also SLF4J-59.

readResolve
protected Object readResolve() throws ObjectStreamException
Replace this instance with a homonymous (same name) logger returned by LoggerFactory. Note that this method is only called during deserialization.This approach will work well if the desired ILoggerFactory is the one references by LoggerFactory. However, if the user manages its logger hierarchy through a different (non-static) mechanism, e.g. dependency injection, then this approach would be mostly counterproductive.
- Returns:
- logger with same name as returned by LoggerFactory
- Throws:
ObjectStreamException
