Ele diz que meu objeto esta detached, mas não entendo pois o spring trata isso pra mim, se não tivesse usando um framework que cuidasse da minha transação tudo bem teria que dar um commit e tudo mais. Outra coisa eu cheguei a executar a aplicação algumas vezes e deu certo, mas agora está dando esse erro o pior que não mexi em nada.
