Spring mvc Mapeo ambiguo encontrado. No se puede asignar el método de bean controlador
Estoy tratando de crear una aplicación que pueda enumerar algunos valores de la base de datos y modificar, agregar, eliminar si es necesario usando Spring 4 y recibo el siguiente error (solo si la anotación "@Controller" está presente en mis dos archivos de controlador, si elimino la anotación de uno de los archivos, funciona pero aparece un mensaje en la consola "no se encontró asignación ... en dispatcherservlet con nombre ...):
