public class ContextDataInjectorFactory extends Object
Factory for ContextDataInjectors. Returns a newContextDataInjector
instance based on the value of system propertylog4j2.ContextDataInjector
. Users may use this system property to specify the fully qualified class name of a class that implements theContextDataInjector
interface. If no value was specified this factory method returns one of the injectors defined inThreadContextDataInjector

createInjector
public static ContextDataInjector createInjector()
Returns a newContextDataInjector
instance based on the value of system propertylog4j2.ContextDataInjector
. If no value was specified this factory method returns one of theContextDataInjector
classes defined inThreadContextDataInjector
which is most appropriate for the ThreadContext implementation.Users may use this system property to specify the fully qualified class name of a class that implements the
ContextDataInjector
interface.When providing a custom
ContextDataInjector
, be aware that this method may be invoked multiple times by the various components in Log4j that need access to context data. This includes the object(s) that populate log events, but also various lookups and filters that look at context data to determine whether an event should be logged.- Returns:
- a ContextDataInjector that populates the
ReadOnlyStringMap
of allLogEvent
objects - See Also:
