Class MethodParameterMessageMapper

java.lang.Object
  org.springframework.integration.message.MethodParameterMessageMapper

All Implemented Interfaces:

InboundMessageMapper<java.lang.Object[]>, OutboundMessageMapper<java.lang.Object[]>

public class MethodParameterMessageMapper
extends java.lang.Object
implements InboundMessageMapper<java.lang.Object[]>, OutboundMessageMapper<java.lang.Object[]>

Prepares arguments for handler methods. The method parameters are matched against the Message payload as well as its headers. If a method parameter is annotated with @Header, the annotation's value will be used as a header name. If such an annotation contains no value, then the parameter name will be used as long as the information is available in the class file (requires compilation with debug settings for parameter names). If the @Header annotation is not present, then the parameter will typically match the Message payload. However, if a Map or Properties object is expected, and the paylaod is not itself assignable to that type, then the MessageHeaders' values will be passed in the case of a Map-typed parameter, or the MessageHeaders' String-based values will be passed in the case of a Properties-typed parameter.
