java.lang.Object org.springframework.integration.MessageHeaders
public final class MessageHeaders
The headers for a Message
.
IMPORTANT: MessageHeaders are immutable. Any mutating operation (e.g., put(..), putAll(..) etc.)
will result in UnsupportedOperationException
To create MessageHeaders instance use fluent MessageBuilder API
MessageBuilder.withPayload("foo").setHeader("key1", "value1").setHeader("key2", "value2");or create an instance of GenericMessage passing payload as
Object
and headers as a regular Map
Map headers = new HashMap(); headers.put("key1", "value1"); headers.put("key2", "value2"); new GenericMessage("foo", headers);
