public final class LogDelegateFactory extends Object
Logdelegates with Spring's logging conventions.
Mainly for internal use within the framework with Apache Commons Logging,
typically in the form of the
spring-jcl bridge but also compatible
with other Commons Logging bridges.
|Modifier and Type||Method and Description|
Create a composite logger that delegates to a primary or falls back on a secondary logger if logging for the primary logger is not enabled.
Create a "hidden" logger whose name is intentionally prefixed with "_" because its output is either too verbose or otherwise deemed as optional or unnecessary to see at any log level by default under the normal package based log hierarchy.
This may be used for fallback logging from lower-level packages that logically should log together with some higher-level package but the two don't happen to share a suitable parent package (e.g. logging for the web and lower-level http and codec packages). For such cases the primary (class-based) logger can be wrapped with a shared fallback logger.
primaryLogger- primary logger to try first
secondaryLogger- secondary logger
tertiaryLoggers- optional vararg of further fallback loggers
clazz- the class for which to create a logger
