Log4j: configure JDBC appender to use Datasource

问题:

I have to configure the JDBC appender to use a datasource..is it possible?

if so , how? My present file looks like so:

# Define the root logger with file appender
log4j.rootLogger = DEBUG, sql

# Define the file appender
log4j.appender.sql=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.sql.URL=jdbc:mysql://localhost/test
# Set Database Driver
log4j.appender.sql.driver=com.mysql.jdbc.Driver
# Set database user name and password
log4j.appender.sql.user=root
log4j.appender.sql.password=password
# Set the SQL statement to be executed.
log4j.appender.sql.sql=INSERT INTO LOGS VALUES ('%x', now() ,'%C','%p','%m')
# Define the xml layout for file appender
log4j.appender.sql.layout=org.apache.log4j.PatternLayout

回答1:

If you want to use a datasource, you need to add the jar file of Apache Extras for Apache log4j ¹ and use the class org.apache.log4j.DBAppender ². e.g.:

# Define the root logger with file appender
log4j.rootLogger = DEBUG, sql

# Define the database appender
log4j.appender.sql=org.apache.log4j.DBAppender
log4j.appender.sql.connectionSource=org.apache.log4j.receivers.db.JNDIConnectionSource
log4j.appender.sql.connectionSource.jndiLocation=java:/comp/env/jdbc/MySQLDS

Notes

1. You can download the file apache-log4j-extras-1.2.17.jar here.
2. This appender uses a database schema (not customizable) and you can find it here. If you want to use other tables, you'll need to rewrite the appender.
