[JAVA] Valeur de réglage de log4jdbc.properties

J'utilisais Log4JDBC pour plus de commodité, mais jusqu'à récemment, je ne savais pas que je pouvais changer certains comportements en mettant un fichier appelé log4jdbc.properties sur le chemin de classe.

Et même si je vais le vérifier officiellement, la démarque est cassée et c'est difficile à lire. Donc, si j'ai un mémo pour moi, je vais en mettre un propre ici. Ci-dessous, le texte original sur log4jdbc.properties est importé tel quel et organisé.

Options

log4jdbc options are controlled via system properties. The simplest way to set these is with the java -D command line option. For example:

java -Dlog4jdbc.drivers=my.funky.DriverClass -classpath ./classes my.funky.Program

Starting with log4jdbc 1.2 beta 2, you can also define any of these property settings in a file named log4jdbc.properties stored in the classpath. log4jdbc will look for properties both in this file (if it exists) and in the system properties, with the file taking precedence for any properties defined in both locations.

property default description since
log4jdbc.drivers One or more fully qualified class names for JDBC drivers that log4jdbc should load and wrap. If more than one driver needs to be specified here, they should be comma separated with no spaces. This option is not normally needed because most popular JDBC drivers are already loaded by default-- this should be used if one or more additional JDBC drivers that (log4jdbc doesn't already wrap) needs to be included. 1.0
log4jdbc.auto.load.popular.drivers true Set this to false to disable the feature where popular drivers are automatically loaded. If this is false, you must set the log4jdbc.drivers property in order to load the driver(s) you want. 1.2beta2
log4jdbc.debug.stack.prefix The partial (or full) package prefix for the package name of your application. The call stack will be searched down to the first occurrence of a class that has the matching prefix. If this is not set, the actual class that called into log4jdbc is used in the debug output (in many cases this will be a connection pool class.) For example, setting a system property such as this: -Dlog4jdbc.debug.stack.prefix=com.mycompany.myapp Would cause the call stack to be searched for the first call that came from code in the com.mycompany.myapp package or below, thus if all of your sql generating code was in code located in the com.mycompany.myapp package or any subpackages, this would be printed in the debug information, rather than the package name for a connection pool, object relational system, etc. 1.0
log4jdbc.sqltiming.warn.threshold Millisecond time value. Causes SQL that takes the number of milliseconds specified or more time to execute to be logged at the warning level in the sqltiming log. Note that the sqltiming log must be enabled at the warn log level for this feature to work. Also the logged output for this setting will log with debug information that is normally only shown when the sqltiming log is enabled at the debug level. This can help you to more quickly find slower running SQL without adding overhead or logging for normal running SQL that executes below the threshold level (if the logging level is set appropriately.) 1.1beta1
log4jdbc.sqltiming.error.threshold Millisecond time value. Causes SQL that takes the number of milliseconds specified or more time to execute to be logged at the error level in the sqltiming log. Note that the sqltiming log must be enabled at the error log level for this feature to work. Also the logged output for this setting will log with debug information that is normally only shown when the sqltiming log is enabled at the debug level. This can help you to more quickly find slower running SQL without adding overhead or logging for normal running SQL that executes below the threshold level (if the logging level is set appropriately.) 1.1beta1
log4jdbc.dump.booleanastruefalse false When dumping boolean values in SQL, dump them as 'true' or 'false'. If this option is not set, they will be dumped as 1 or 0 as many databases do not have a boolean type, and this allows for more portable sql dumping. 1.2alpha1
log4jdbc.dump.sql.maxlinelength 90 When dumping SQL, if this is greater than 0, than the dumped SQL will be broken up into lines that are no longer than this value. Set this value to 0 if you don't want log4jdbc to try and break the SQL into lines this way. In future versions of log4jdbc, this will probably default to 0. 1.2alpha1
log4jdbc.dump.fulldebugstacktrace false If dumping in debug mode, dump the full stack trace. This will result in EXTREMELY voluminous output, but can be very useful under some circumstances when trying to track down the call chain for generated SQL. 1.2alpha1
log4jdbc.dump.sql.select true Set this to false to suppress SQL select statements in the output. 1.2alpha1
log4jdbc.dump.sql.insert true Set this to false to suppress SQL insert statements in the output. 1.2alpha1
log4jdbc.dump.sql.update true Set this to false to suppress SQL update statements in the output. 1.2alpha1
log4jdbc.dump.sql.delete true Set this to false to suppress SQL delete statements in the output. 1.2alpha1
log4jdbc.dump.sql.create true Set this to false to suppress SQL create statements in the output. 1.2alpha1
log4jdbc.dump.sql.addsemicolon false Set this to true to add an extra semicolon to the end of SQL in the output. This can be useful when you want to generate SQL from a program with log4jdbc in order to create a script to feed back into a database to run at a later time. 1.2alpha1
log4jdbc.statement.warn false Set this to true to display warnings (Why would you care?) in the log when Statements are used in the log. NOTE, this was always true in releases previous to 1.2alpha2. It is false by default starting with release 1.2 alpha 2. 1.2alpha2
log4jdbc.trim.sql true Set this to false to not trim the logged SQL. (Previous versions always trimmed the SQL.) 1.2beta2
log4jdbc.trim.sql.extrablanklines true Set this to false to not trim extra blank lines in the logged SQL (by default, when more than one blank line in a row occurs, the contiguous lines are collapsed to just one blank line.) (Previous versions didn't trim extra blank lines at all.) 1.2
log4jdbc.suppress.generated.keys.exception false Set to true to ignore any exception produced by the method, Statement.getGeneratedKeys() (Useful for using log4jdbc with Coldfusion.) 1.2beta2
