[英]Postgres how to make more than one transaction
我在数据库中不止一个插入问题，最初的问题是我无法插入表，因为我需要插入最后一条记录的最后一个ID。
如果我尝试在表中插入更多记录，那行不通，为什么？ 那是因为插入直到提交事务为止，所以它只会插入最后一个id插入的一条记录。 这是我的Java代码：
@Service
@Transactional
public class ServicioEvaluacionImpl implements ServicioEvaluacion{
@Autowired
@Qualifier("sfGas")
SessionFactory sf;
Session session;
@Autowired
EncuestaDaoImpl encuestaDao;
@Autowired
ClienteDaoImpl clienteDao;
@Autowired
DelegacionDaoImpl delegacionDao;
@Autowired
ServicioGenericoCRUD servicioCRUD;
public void guardarEvaluacion(String parametros) {
JSONObject obj = new JSONObject(parametros);
JSONObject cliente = obj.getJSONObject("cliente");
Integer lastIdCliente = new Integer(0);
String nombre = cliente.getString("nombre");
String apellidos = cliente.getString("apellidos");
String sexo = cliente.getString("sexo");
String email = cliente.getString("email");
String area = cliente.getString("area");
String puesto = cliente.getString("puesto");
int delegacion = cliente.getInt("delegacion");
Delegacion delegacionObj = delegacionDao.getDelegacion(delegacion);
Cliente clienteObj = new Cliente();
clienteObj.setNombre(nombre);
clienteObj.setApellidos(apellidos);
clienteObj.setEmail(email);
clienteObj.setSexo(sexo);
clienteObj.setPuesto(puesto);
clienteObj.setArea(area);
clienteObj.setDelegacion(delegacionObj);
//clienteDao.setCliente(clienteObj);
Transaction transaction = null;
try{
Session session = sf.getCurrentSession();
//obtiene ultimo id insertado
List<Object> qTemp = servicioCRUD.consultaSQL("Select max(id_cliente) from cliente;");
for(Object registro : qTemp){
lastIdCliente = Integer.parseInt(registro.toString());
}
int ultimoID = lastIdCliente.intValue()+1;
clienteObj.setIdCliente(ultimoID);
servicioCRUD.create(clienteObj);
JSONArray evaluaciones = obj.getJSONArray("evaluaciones");
JSONArray idPregunta = obj.getJSONArray("idPregunta");
JSONArray comentarios = obj.getJSONArray("comentarios");
String sugerencias = obj.getString("sugerencias");
Respuestas respuesta = new Respuestas();
Comentarios comentario = new Comentarios();
Sugerencias sugerencia = new Sugerencias();
respuesta.setCliente(clienteObj);
comentario.setCliente(clienteObj);
sugerencia.setCliente(clienteObj);
java.util.Date date = new java.util.Date();
java.sql.Date sqlDate = new java.sql.Date(date.getTime());
sugerencia.setFecha(sqlDate);
sugerencia.setSugerencia(sugerencias);
for (int i = 0; i < evaluaciones.length(); i++) {
transaction = session.beginTransaction();
Encuesta pregunta = encuestaDao.getEncuesta(idPregunta.getInt(i));
respuesta.setEncuesta(pregunta);
int respuestaID=0;
//obtiene ultimo id de respuesta
qTemp = servicioCRUD.consultaSQL("SELECT max(id_respuesta) FROM respuestas");
for(Object registro : qTemp){
Integer lastIdPregunta = Integer.parseInt(registro.toString());
respuestaID = lastIdPregunta.intValue()+1;
System.out.println("loop::"+i+" -ult id resp: "+ respuestaID);
}
respuesta.setCalificacion((short) evaluaciones.getInt(i));
respuesta.setIdRespuesta(respuestaID);
//insercion respuestas
respuesta.setFecha(sqlDate);
servicioCRUD.create(respuesta);
//si no hay comentarios no insertar
if(!comentarios.getString(i).equals("")){
int commentID = 0;
qTemp = servicioCRUD.consultaSQL("SELECT max(id_comentario) FROM comentarios");
for(Object registro : qTemp){
Integer lastIdComent = Integer.parseInt(registro.toString());
commentID = lastIdComent.intValue()+1;
}
comentario.setEncuesta(pregunta);
comentario.setIdComentario(commentID);
comentario.setComentario(comentarios.getString(i));
comentario.setFecha(sqlDate);
servicioCRUD.create(comentario);
}
transaction.commit();
}
transaction = session.beginTransaction();
if(!sugerencias.equals("")){
int sugerenciaID = 0;
qTemp = servicioCRUD.consultaSQL("SELECT max(id_comentario) FROM comentarios");
for(Object registro : qTemp){
Integer sugerenciaIdComent = Integer.parseInt(registro.toString());
sugerenciaID = sugerenciaIdComent.intValue()+1;
}
sugerencia.setIdSugerencia(sugerenciaID);
servicioCRUD.create(sugerencia);
}
transaction.commit();
}catch(Exception e){
e.printStackTrace();
transaction.rollback();
}finally{
session.flush();
}
}
}
我试图在循环结束时提交，但它给出了一个错误。 没有解决方法，还有另一种方法可以修复表序列？ 如果没有，我该怎么办？ 我需要按顺序插入这些记录。
编辑：我解决了表序列的问题，仍然我不能将那些多个记录保存到数据库中，这次没有堆栈跟踪错误。
堆栈跟踪：

问题不在于您的承诺。 这是NullPointerException第192行。
我不知道第192行是哪一行，但我敢打赌，这是您交易记录栏之外的一行。 当您尝试回滚事务时，您会从Catch - Rollback获得另一个异常。
查找Null变量，就可以解决您的问题。 当您尝试回滚时，您还可以检查事务是否已打开。 或添加更多try {} catch {}块，因为您的代码很容易出错。
