He estado tratando de serializar un objeto a un CSVString pero el objeto contiene unList y@JsonUnwrapped no funciona enList objetos.

Salida de muestra esperada:

color,part.name\n
red,gearbox\n
red,door\n
red,bumper

Salida real:

com.fasterxml.jackson.core.JsonGenerationException: Unrecognized column 'name':

Aqui esta mi codigo: (La mayor parte son los 2 POJO's)

}

Nada de lo que intento parece funcionar, he leído todosenviar en stackoverflow y github sobre el tema, pero no puedo encontrar una solución que funcione.

Disculpe las anotaciones inútiles que dejé sin razón y si responde con un código, no dude en eliminarlas.
