Method Detail

applyLoggerLevel

public static void applyLoggerLevel(java.util.Properties props)

Applies the logger level requested through the wrapperLoggerLevel connection property, if it's specified. The level is set on the driver's parent logger (software.amazon.jdbc), so loggers that have their own level explicitly configured (for instance, through a logging.properties file) are not affected and keep their configured level.

This method should be called as early as possible while establishing a connection so that the driver's own log messages are governed by the requested level.

Parameters:

props - the connection properties to get the requested logger level from

Throws:

java.lang.IllegalArgumentException - if the specified logger level isn't a valid Level
