 /**
+ * A MessageProcessor implementation that invokes a method on a target Object.
+ * The Method instance or method name may be provided as a constructor argument.
+ * If a method name is provided, and more than one declared method has that name,
+ * the method-selection will be dynamic, based on the underlying SpEL method
+ * resolution. Alternatively, an annotation type may be provided so that the
+ * candidates for SpEL's method resolution are determined by the presence of that
+ * annotation rather than the method name.
