Só tem um lugar que eu coloquei o bigint que foi no banco de dados , olhei tudo nas classes não encontrei nada que poderia esta ocasionando esse erro.Vou manda as classes para você da uma olha e ve onde mais ou menos esta esse erro. package br.com.caelum.tarefas.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import br.com.caelum.tarefas.dao.JdbcTarefaDao; import br.com.caelum.tarefas.modelo.Tarefa; @Controller public class TarefasController { @RequestMapping("novaTarefa") public String form(){ return "tarefa/formulario"; } @RequestMapping("adicionaTarefa") public String adiciona(Tarefa tarefa){ JdbcTarefaDao dao = new JdbcTarefaDao(); dao.adiciona(tarefa); return "tarefa/adicionado"; } } classe do DAO package br.com.caelum.tarefas.dao; import java.sql.Connection; import java.sql.Date; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.SQLException; import java.util.ArrayList; import java.util.Calendar; import java.util.List; import br.com.caelum.tarefas.modelo.Tarefa; import br.com.caelum.tarefas.ConnectionFactory; public class JdbcTarefaDao { private final Connection connection; public JdbcTarefaDao() { this.connection = new ConnectionFactory().getConnection(); } public void adiciona(Tarefa tarefa) { String sql = "insert into tarefas (descricao, finalizado) values (?,?)"; PreparedStatement stmt; try { stmt = connection.prepareStatement(sql); stmt.setString(1, tarefa.getDescricao()); stmt.setBoolean(2, tarefa.isFinalizado()); stmt.execute(); } catch (SQLException e) { throw new RuntimeException(e); } } public void remove(Tarefa tarefa) { if (tarefa.getId() == null) { throw new IllegalStateException("Id da tarefa não deve ser nula."); } String sql = "delete from tarefas where id = ?"; PreparedStatement stmt; try { stmt = connection.prepareStatement(sql); stmt.setLong(1, tarefa.getId()); stmt.execute(); } catch (SQLException e) { throw new RuntimeException(e); } } public void altera(Tarefa tarefa) { String sql = "update tarefas set descricao = ?, finalizado = ?, dataFinalizacao = ?
