Bom dia!
Tenho que preencher uma TableView e estou fazendo o seguinte:
classe de dados:
public class Dados {
private String nome;
private String telefone;
//Metodos construtor
public Dados() {
}
public Dados(String nome, String telefone) {
this.nome = nome;
this.telefone = telefone;
}
//Metodos get set
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getTelefone() {
return telefone;
}
public void setTelefone(String telefone) {
this.telefone = telefone;
}
}
//Classe sql
public class Sql {
//Metodo carrega lista
public List getList(){
List dados = new ArrayList<>();
Connection conexao = ConexaoDB.getConexao();
String sql = "SELECT * FROM tbcadastros";
try {
PreparedStatement smt = conexao.prepareStatement(sql);
ResultSet rs = smt.executeQuery();
while(rs.next()){
Dados dado = new Dados();
dado.setNome(rs.getString("nome"));
dado.setTelefone(rs.getString("Telefone"));
dados.add(dado);
}
ConexaoDB.close(conexao, smt, rs);
} catch (SQLException ex) {
System.out.println("Erro! Lista sem retorno");
return null;
}
return dados;
}
}
//Classe controller
public class Controle implements Initializable {
@FXML private TableView tabelaCadastros;
@FXML private TableColumn <Dados, String> tbcolNome;
@FXML private TableColumn <Dados, String> tbcolTelefone;
//inicia os controles da tela
<a class="mention" href="/u/override">@Override</a>
public void initialize(URL url, ResourceBundle rb) {
carregaTabelaCadastros();
}
// metodo carrega banco na tabela
public void carregaTabelaCadastros() {
tbcolNome.setCellValueFactory(new PropertyValueFactory(“nome”));
tbcolTelefone.setCellValueFactory(new PropertyValueFactory(“telefone”));
tabelaCadastros.setItems(atualizaTabela());
}
//metodo carrega banco na tabela
public ObservableList atualizaTabela() {
Sql cadastros = new SqlL();
return FXCollections.observableArrayList(cadastros.getList());
}
}
Carrega a tela Abri o controle mas não carrega os dados. Retorna esse erro:
