Class HibernateLoggerHelper

java.lang.Object

org.slf4j.impl.HibernateLoggerHelper

public class HibernateLoggerHelper
extends java.lang.Object

This class creates and administrates loggers for the hibernate framework on behalf of the slf4j-ACS logger factory ACSLoggerFactory.

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.

Field Detail

HIBERNATE_LOGGER_NAME_PREFIX

public static final java.lang.String HIBERNATE_LOGGER_NAME_PREFIX

Mapped to all hibernate loggers except those from HIBERNATE_SQL_LOGGER_NAME_PREFIX.

Constant Field Values

HIBERNATE_SQL_LOGGER_NAME_PREFIX

public static final java.lang.String HIBERNATE_SQL_LOGGER_NAME_PREFIX

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.

getLogger

clearDelegateLoggers

public void clearDelegateLoggers()

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.
