Annotation Type Header

@Target(value=PARAMETER)
@Retention(value=RUNTIME)
@Documented
public @interface Header

Annotation indicating that a method parameter's value should be retrieved from the message headers. The value of the annotation can either be a header name (e.g., 'foo') or SpEL expression (e.g., 'payload.getCustomerId()') which is quite useful when the name of the header has to be dynamically computed. It also provides an optional 'required' property which specifies whether the attribute value must be available within the header. The default value for 'required' is true.
