ExpressionConfig

A configuration object for expression-related settings. This object is responsible for loading and providing specific configurations used to control behavior such as log levels during expression matching.

It uses the ConfigFactory to load configuration settings and determines the appropriate log level for expression matching based on the number.expression.match-log-level property from the configuration.

The supported log levels are:

• "off": Corresponds to LogOff.
• "info": Corresponds to LogInfo.
• "debug": Corresponds to LogDebug.

If the property is not specified or does not match any of the expected values, the log level defaults to LogOff.
