Detailed Description

ACSLoggerFactory is an implementation of slf4j's ILoggerFactory based on AcsLoggers, allowing for hibernate logs to be streamed into the ACS logging system. This class gets connected to the slf4j framework via StaticLoggerBinder, which is pulled in by slf4j from the classpath. Therefore no other slf4j bindings to different logging frameworks are allowed on the classpath.

A side effect of this is that any other software package which in the future might also rely on slf4j logging will get a logger called "hibernate" or "hibernate@<process name>".

Simplification of the large number of hibernate loggers: The hibernate framework tries to use separate loggers with names being those of its java classes, e.g. "org.hibernate.cfg.Ejb3Column". ACS maps all of these logger requests to only 2 different loggers, which can be configured separately:

• The default logger is called "hibernate", or "hibernate@<process-name>" if a process/container name is known to the ACS logging libs. See also HIBERNATE_LOGGER_NAME_PREFIX.
• SQL related hibernate loggers are mapped to "hibernateSQL", or "hibernateSQL@<process-name>" if a process/container name is known to the ACS logging libs. See also HIBERNATE_SQL_LOGGER_NAME_PREFIX.

A similar name reduction is used for JacORB loggers, see alma.acs.logging.adapters.JacORBLoggerFactory#getNamedLogger(String).

Should only be called by tests. For example, JUnit test cases that use different logger names for every test need to call this in order for hibernate loggers to be re-created.

Member Data Documentation

final String org.slf4j.impl.ACSLoggerFactory.HIBERNATE_LOGGER_NAME_PREFIX = "hibernate" [static]

Mapped to all hibernate loggers except those from HIBERNATE_SQL_LOGGER_NAME_PREFIX.

Referenced by org.slf4j.impl.ACSLoggerFactory.getLogger().

final String org.slf4j.impl.ACSLoggerFactory.HIBERNATE_SQL_LOGGER_NAME_PREFIX = "hibernateSQL" [static]

Mapped to hibernate loggers "org.hibernate.SQL" (for SQL statements) and "org.hibernate.type.xyz" (for SQL binding parameters).

Hibernate announces that version 4 will rename the SQL logger to "org.hibernate.jdbc.util.SQLStatementLogger" which is why we already map that currently not existing logger name to the same sql logger.
