I developed an application using Java Spring (backend api), mysql (DB) and Anguljar JS (frontend) that is designed to let users schedule an appointment. The endtime of each appointment is five minutes after its starttime, between 8 o’clock and 2 p.m.
In my data base I have the following information:
• A table named “turno” which contains the parameters time and date of the appointments given.
• Another table contains all the available appointments.
I want to substract both arrays so as to see which appointments have not been given yet. The objective is not to allow users to fix an appointment that has already been made by someone else.
Does anyone have any idea how to do this?
Data examples:
Java Example:
#Entity
#Table(name = "turno")
public class Turno implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String solicitante;
private String telefono;
private TipoDocumento tipoDocumento;
private String numeroDocumento;
private String email;
private Horario horario;
private String numeroTurno;
private String fecha;
private Date formatfecha;
private Date controlFecha;
#Id
#GeneratedValue
#Column(name = "id")
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Column(name = "solicitante")
public String getSolicitante() {
return solicitante;
}
public void setSolicitante(String solicitante) {
this.solicitante = solicitante;
}
#Column(name = "telefono")
public String getTelefono() {
return telefono;
}
public void setTelefono(String telefono) {
this.telefono = telefono;
}
#Column(name = "numero_documento")
public String getNumeroDocumento() {
return numeroDocumento;
}
public void setNumeroDocumento(String numeroDocumento) {
this.numeroDocumento = numeroDocumento;
}
#Column(name = "email")
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#ManyToOne(cascade = CascadeType.MERGE)
#JoinColumn(name = "horario", referencedColumnName = "id")
public Horario getHorario() {
return horario;
}
public void setHorario(Horario horario) {
this.horario = horario;
}
#Column(name = "numero_turno")
public String getNumeroTurno() {
return numeroTurno;
}
public void setNumeroTurno(String numeroTurno) {
this.numeroTurno = numeroTurno;
}
#Column(name = "fecha")
public String getFecha() {
return fecha;
}
public void setFecha(String fecha) {
this.fecha = fecha;
}
#Column(insertable = false, updatable = false, name = "fecha")
public Date getFormatFecha() {
return formatfecha;
}
public void setFormatFecha(Date formatfecha) {
this.formatfecha = formatfecha;
}
#ManyToOne(cascade = CascadeType.MERGE)
#JoinColumn(name = "tipoDocumento", referencedColumnName = "id")
public TipoDocumento getTipoDocumento() {
return tipoDocumento;
}
public void setTipoDocumento(TipoDocumento tipoDocumento) {
this.tipoDocumento = tipoDocumento;
}
#Column(name = "fecha_control")
public Date getControlFecha() {
return controlFecha;
}
public void setControlFecha(Date controlFecha) {
this.controlFecha = controlFecha;
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((numeroTurno == null) ? 0 : numeroTurno.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Turno other = (Turno) obj;
if (numeroTurno == null) {
if (other.numeroTurno != null)
return false;
} else if (!numeroTurno.equals(other.numeroTurno))
return false;
return true;
}
}
Updated
Heres how I fixed it in case anyone is interested:
Method in the controller:
#RequestMapping(value = "/horario/{fecha}", method = RequestMethod.GET)
#ResponseBody
public Object queryHorariosLibres(#PathVariable("fecha") Date fecha) {
List<Long> horariosLibres = null;
List<Long> turnosTomados = turnoService.getTurnosTomados(fecha);
Calendar dia = new GregorianCalendar();
dia.setTime(fecha);
Horario horario = horarioRepository.findByDia(dia.get(Calendar.DAY_OF_WEEK));
horariosLibres = horario.getHorariosLibres(turnosTomados);
if (horariosLibres == null) {
return "hola";
}
else
return horariosLibres;
}
Local methods:
#Transient
public List<Long> getHorarios(){
List<Long> horarios = new ArrayList<Long>();
for(Long i = horarioInicio; i <= horarioFin; i+=300){
horarios.add(i);
}
return horarios;
}
#Transient
public List<Long> getHorariosLibres(List<Long> horariosTomados){
List<Long> horariosLibres = getHorarios();
horariosLibres.removeAll(horariosTomados);
return horariosLibres;
}

I have a problem when using Long type attributes, I created an attribute called 'Cnh' which receives a 11 digit code, I already put the L in the end of the value, but when I run it in JUnit it still says Integer number too large: 06161567318l.
Is there any possible way I can avoid it
I don't wanna change the attribute type, because I have another which has the same problem but it is a 'hashcode' (it would be really tough to change)

I am new to JavaEE and I am having a problem with persisting a table that has foreign keys pointing to the primary key of another table using entity classes and ejb's entity manager. I am using Netbeans.
I have an entity called 'property' and have another entity called 'offer' which holds the foreign key pointing to the primary key of the property. So basically, the logic is that one property can have many offers. Therefore, I am trying to add new offers in the 'offer' table using the entity manager but I am not being able to do it. You can look at the code and see what I maybe missing.

Servlet that connects the JSP with the EJB:
String action = request.getParameter("action");
String currencyType = request.getParameter("ddlCurrencyType");
String amount = request.getParameter("offerAmount");
String propertyIdStr = request.getParameter("hdnbt");

{

currentTime = df1.parse(df1.format(currentTime));
} catch (ParseException e) {
}
Buyer buyer = buyerDAO.GetBuyer(1);
Property property = propertyDAO.GetProperty(propertyId);
Offer offer = new Offer("Pending", amount, amount, currentDate, currentTime, buyer, property);
offerDAO.Add(offer);
}
else

}
request.setAttribute("allProperty", propertyDAO.GetAllProperty());
request.getRequestDispatcher("AdministerProperty.jsp").forward(request, response);
Am I missing something here? I have followed a tutorial which didn't have a foreign key guidance but tried to use my own logic to go around it but it didn't work. I cannot find a reliable source that uses the method similar to me. Most of the resources I find are for Hibernate but I am using EJB.
It seems that the method which retrieves the Property and the method that persists the Offer are run in a separate transactions (DAOs being the Stateless session beans).
That would mean that the Offer is populated and persisted with a detached Property, so the persistence provider is not aware of it.
Not sure why an exception is not raised but you would have to merge the Property first or do the query in the same transaction as you persist the Offer:
#Override
public void Add(Offer offer, int peropertyId) {
Property property = em.find(Property.class, propertyId);
offer.setPeropertyId(property);
em.persist(offer);
}
or
#Override
public void Add(Offer offer, Property peroperty) {
Property managedProperty = em.merge(property);
offer.setPeropertyId(managedProperty);
em.persist(offer);
}
I fixed it. If you look at the code for servlet, it was the problem with my if condition that checks the action parameter. It was meant to be if action is not empty but it checks if action is empty. I found this issue by creating an integer that increments itself when it reaches certain stages within the code.
I think you were right on the fact that I had to do the getting property id and buyer id on the same transaction. Otherwise that would have been the next issue for me. Thank you.
i have a servlet in that i add all data relted to child and parent table like

int physicianId=Integer.parseInt(helper.getPhysicianId());

String discription=helper.getDiscription();
String condition=helper.getcondition();
String rules=helper.getRules();
String fields=helper.getFields();
String query = (String) session.getAttribute("query");
List<QueryBuilderCondition> conditionList = new ArrayList<QueryBuilderCondition>();
net.sf.json.JSONObject jObject=new net.sf.json.JSONObject();
net.sf.json.JSONArray jArray = new net.sf.json.JSONArray();
String result="";
try {

conditionList.add(qbCondition);
}
builder.setQueryBuilderConditionCollection(conditionList);
System.out.println("==========conditionList========="+conditionList.toString()+ "======SIZE is ============="+conditionList.size());
result=new QueryBuilderJpaController().saveQuery(builder);

}
}catch(Exception ex){
result="error";
ex.printStackTrace();
logger.log(Level.INFO,"===============saveQuery==============="+ex.getMessage());
}
jArray.add(jObject);
return null;
}
from here i call my jpa control
public String saveQuery(QueryBuilder builder) {

String result = "";
try {

I very confused on how to save data in the database. I'll take the data from a table and then save.

Assuming you have an object variable layoutsos of type Layoutsos that has been persisted to the DB or retrieved from the DB. Here's how your code should look like when persisting the Ordemservico entity.
Ordemservico o = new Ordemservico();
o.getOrdemproducaoList().add(layoutsos);
em.persist(o);
If this is a bi-directional relationship, you should set both side of the relationship before persisting.
Layoutsos layoutsos = new Layoutsos();
Ordemservico o = new Ordemservico();
o.getOrdemproducaoList().add(layoutsos);
layoutsos.getOrdermserviceoList().add(o);
em.persist(layoutsos);
em.persist(o);
this is my first post, so please bear with me if i do make any errors.
I get an error " java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST"
whenever i want to query(add,edit,delete) the database.

The field

in the Donations entity is not configured for cascading. Try changing it to:
#ManuToOne(optional = false, cascade = CascadeType.ALL)
private Sponsors sponsorid;
