Quando eu adiciono manualmente a coluna no banco funciona normalmente, porém quando eu adiciono qualquer atributo na entidade modelo aparece esse erro informando que tal coluna não existe, alguém sabe o que poderia ser?

Tenta colocar a anotação @Temporal no atributo da data, e esse atributo testador ele esta reclamando que nao existe no seu modelo, vc criou as tabelas manualmente ou o hibernate que criou?
