java.lang.Object

org.springframework.integration.util.AbstractExpressionEvaluator

org.springframework.integration.handler.support.MapArgumentResolver

All Implemented Interfaces:

Aware, BeanFactoryAware, InitializingBean, HandlerMethodArgumentResolver

public class MapArgumentResolver
extends AbstractExpressionEvaluator
implements HandlerMethodArgumentResolver

A HandlerMethodArgumentResolver implementation to resolve argument for the MethodParameter as a Map or Properties.

The Message.getHeaders() is used when MethodParameter is marked with the Headers annotation or Message.getPayload() isn't Map or Properties compatible.

If MethodParameter is of Properties type and Message.getPayload() is a String containing = symbol, the MapArgumentResolver uses ConversionService trying to convert that String to the Properties object.
