Vê se alguém pode me ajudar.
Estou estudando a apostila da Caelum FJ21,porém ao invés de utilizar a MySql optei pelo POSTGRES.porém quando vou fazer o exercício AdicionaTarefa um registro no banco dá o seguinte erro.
Sou novo em Java, vê se conseguir se claro.
Para conexão utilizo a Classe JdbcTarefaDao.
@Repository
public class JdbcTarefaDao {
private final Connection connection;
@Autowired
public JdbcTarefaDao(DataSource dataSource) {
try {
this.connection =dataSource.getConnection();
} catch (SQLException e) {
throw new RuntimeException(e);
}
}
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 class AdicionaTarefa {
public static void main(String[] args) {
Tarefa tarefa = new Tarefa();
tarefa.setDescricao("Estudar JPA e Hibernate");
tarefa.setFinalizado(true);
tarefa.setDataFinalizacao(Calendar.getInstance());
EntityManagerFactory factory = Persistence.
createEntityManagerFactory("tarefas");
EntityManager manager = factory.createEntityManager();
manager.getTransaction();
manager.persist(tarefa);
manager.getTransaction();
System.out.println("ID da tarefa :"+ tarefa.getId());
manager.close();
}
}
