Class CompositePropertySource



  • public class CompositePropertySource
    extends EnumerablePropertySource<java.lang.Object>
    Composite PropertySource implementation that iterates over a set of PropertySource instances. Necessary in cases where multiple property sources share the same name, e.g. when multiple values are supplied to @PropertySource.

    As of Spring 4.1.2, this class extends EnumerablePropertySource instead of plain PropertySource, exposing getPropertyNames() based on the accumulated property names from all contained sources (as far as possible).

    3.1.1

      • toString

        public java.lang.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 the hash code 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.

        Overrides:
        toString in class PropertySource<java.lang.Object>
