Examples of MessageHeaders

com.sun.xml.ws.api.message.MessageHeaders
Interface representing all the headers of a {@link Message}
net.noderunner.http.MessageHeaders
Contains a list of message headers. @author Elias Ross
org.apache.muse.ws.addressing.MessageHeaders
MessageHeaders provides WS-Addressing processing for SOAP message headers. It can be used to parse SOAP headers according to WS-A spec and read the values or create a new set of headers that can be serialized to a set of valid SOAP headers.

This class references the W3C DOM API rather than the SAAJ API because SOAPElements can usually be converted into DOM Elements very easily, but having a DOM Element does not mean that the user code has access to (or wants access to) the SAAJ API and its SOAP factories. @author Dan Jemiolo (danj) @see EndpointReference
org.springframework.integration.MessageHeaders
org.springframework.integration.core.MessageHeaders
org.springframework.integration.message.MessageHeaders
org.springframework.messaging.MessageHeaders
The headers for a {@link Message}.
IMPORTANT: This class is immutable. Any mutating operation such as {@code put(..)}, {@code putAll(..)} and others will throw{@link UnsupportedOperationException}.
Subclasses do have access to the raw headers, however, via {@link #getRawHeaders()}.
One way to create message headers is to use the {@link org.springframework.messaging.support.MessageBuilder MessageBuilder}:
```
 MessageBuilder.withPayload("foo").setHeader("key1", "value1").setHeader("key2", "value2"); 
```
A second option is to create {@link org.springframework.messaging.support.GenericMessage}passing a payload as {@link Object} and headers as a {@link Map java.util.Map}:
```
 Map headers = new HashMap(); headers.put("key1", "value1"); headers.put("key2", "value2"); new GenericMessage("foo", headers); 
```
A third option is to use {@link org.springframework.messaging.support.MessageHeaderAccessor}or one of its subclasses to create specific categories of headers. @author Arjen Poutsma @author Mark Fisher @author Gary Russell @since 4.0 @see org.springframework.messaging.support.MessageBuilder @see org.springframework.messaging.support.MessageHeaderAccessor
