toString

public String toString()

Description copied from class: PropertySource

Produce concise output (type and name) if the current log level does not include debug. If debug is enabled, produce verbose output including hashcode of the PropertySource instance and every name/value property pair. This variable verbosity is useful as a property source such as system properties or environment variables may contain an arbitrary number of property pairs, potentially leading to difficult to read exception and log messages.
