Class ContentTypeDelegatingMessageConverter

  • All Implemented Interfaces:
    MessageConverter
    public class ContentTypeDelegatingMessageConverter
extends java.lang.Object
implements MessageConverter
    A composite MessageConverter that delegates to an actual MessageConverter based on the contentType header. Supports a default converter when no content type matches. Note: the MessageProperties requires a content type header to select a converter when used for outbound conversion, but the converter will (generally) override it to match the actual conversion.
