  • Hello, avoid adding information in the comments, instead edit your question and add the information there. If you need to format some code select the code and click the button {}. I ask you to post the contents of the class Categoria.java and also the class to which the variable belongs categoriaRepository (would be CategoriaRepository.java?).

  • Try to post code as text and not as images. I ask the kindness to correct so that other users can take advantage of the question too.

  • OK Piovezan, thank you very much!

  • The staff is still hammering the negative votes, I think better to add the error log to the question too or else someone please explain the negative for the illustrious padawan correct the question. :)

The Setter country nome is not doing the assignment correctly.

In class Categoria.java, in the method setNome(String name), change the parameter name for nome.

This way the assignment will be correct:

public void setNome(String nome) {
    this.nome = nome;
}
