Error while using JPQL to query by joining tables

I am trying to fetch list of train entities using source and destination properties of route entity which has one to many relationship with each other. The train table having route id as foreign key. The table names are route and train respectively. Please help me as the query is throwing java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List com.infyrail.app.repository.RouteRepository.findBySourceDestination(java.lang.String,java.lang.String)!
RouteRepository:
public interface RouteRepository extends JpaRepository<RouteEntity, Integer> {
#Query("SELECT t FROM train t JOIN route r WHERE r.source=?1 AND r.destination=?2")
public List<TrainEntity> findBySourceDestination(String source,String destination);
}
RouteEntity:
#Entity

public class RouteEntity {
#Id
#GenericGenerator(name="route_id",
strategy="com.infyrail.app.generator.RouteIdGenerator")
#GeneratedValue(generator = "route_id")
#Min(value = 100)
#Max(value = 999)
Integer id;
String source;
String destination;
#OneToMany(mappedBy = "route",
cascade=CascadeType.ALL,orphanRemoval = true)
private List<TrainEntity> trainList;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}

}
public void setSource(String source) {
this.source = source;
}
public String getDestination() {
return destination;
}
public void setDestination(String destination) {
this.destination = destination;
}
public List<TrainEntity> getTrainList() {
return trainList;
}
public void setTrainList(List<TrainEntity> trainList) {
this.trainList = trainList;
}
}
TrainEntity:

public void setRoute(RouteEntity route) {

public void setArrivalTime(String arrivalTime) {
this.arrivalTime = arrivalTime;
}
public String getDepartureTime() {

public void setDepartureTime(String departureTime) {
this.departureTime = departureTime;
}
public Double getFare() {
return fare;
}
public void setFare(Double fare) {
this.fare = fare;
}
}

Here is the problem. Your query should define the table bean name instead of the actual table name.
In your case you should use TrainEntity instead of train and RouteEntity instead of route.
public interface RouteRepository extends JpaRepository<RouteEntity, Integer> {
#Query("SELECT t FROM TrainEntity t JOIN RouteEntity r WHERE r.source=?1 AND r.destination=?2")
public List<TrainEntity> findBySourceDestination(String source,String destination);
}

How to customize response from #query in springboot API

I have a problem with my API #query reponse in SpringBoot.
First I will show u my code:
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public Ksiazka find(#RequestParam("id") int id){
String autor = ksiazkaRepo.findInfoById(id);
Ksiazka ksiazka = new Ksiazka();
ksiazka.setAutor(autor);
return ksiazka;
}
**#Repository
public interface KsiazkaRepo extends JpaRepository<Ksiazka, Integer> {
#Query(value = "SELECT ksiazka.tytul, ksiazka.autor FROM IEci8d0gZc.ksiazka WHERE ksiazka.id_ksiazka = :id", nativeQuery = true)
String findInfoById(#Param("id") int id);
}**
#Entity
#Validated
public class Ksiazka {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int idKsiazka;
private int idKategoria;
private String isbn;
#JsonView(OnlyName.class)
private String tytul;
#JsonView(OnlyName.class)
private String autor;
private int stron;
private String wydawnictwo;
private int rokWydania;
private String opis;
public Ksiazka(){ }
public Ksiazka(int idKsiazka, int idKategoria, String isbn, String tytul, String autor, int stron, String wydawnictwo, int rokWydania, String opis) {
this.idKsiazka = idKsiazka;
this.idKategoria = idKategoria;
this.isbn = isbn;
this.tytul = tytul;
this.autor = autor;
this.stron = stron;
this.wydawnictwo = wydawnictwo;
this.rokWydania = rokWydania;
this.opis = opis;
}
public int getIdKsiazka() {
return idKsiazka;
}
public void setIdKsiazka(int idKsiazka) {
this.idKsiazka = idKsiazka;
}
public int getIdKategoria() {
return idKategoria;
}
public void setIdKategoria(int idKategoria) {
this.idKategoria = idKategoria;
}
public String getIsbn() {
return isbn;
}
public void setIsbn(String isbn) {
this.isbn = isbn;
}
public String getTytul() {
return tytul;
}
public void setTytul(String tytul) {
this.tytul = tytul;
}
public String getAutor() {
return autor;
}
public void setAutor(String autor) {
this.autor = autor;
}
public int getStron() {
return stron;
}
public void setStron(int stron) {
this.stron = stron;
}
public String getWydawnictwo() {
return wydawnictwo;
}
public void setWydawnictwo(String wydawnictwo) {
this.wydawnictwo = wydawnictwo;
}
public int getRokWydania() {
return rokWydania;
}
public void setRokWydania(int rokWydania) {
this.rokWydania = rokWydania;
}
public String getOpis() {
return opis;
}
public void setOpis(String opis) {
this.opis = opis;
}
And my interface OnlyName is empty.
When I'm using it like that like it is right not I can get simple response
Like:
{
"tytul": null,
"autor": "Mistrz czystego kodu. Kodeks postępowania profesjonalnych programistów,Robert C. Martin"
}
I understand that my response from #query is in String and that's why I'm getting only one result, but How should I change to get all String or something like that? Maybe String[]?
I can also create 2 different custom asking #query and get from them
1. imie,
2. nazwisko,
but this should not be the case.
Many thanks for help,
Ciao
UPDATE

Follow the steps here
In here, I am trying to tell you how to do this simply
Change the query , It should return list
#Query(value = "SELECT ksiazka.tytul, ksiazka.autor FROM IEci8d0gZc.ksiazka WHERE ksiazka.id_ksiazka = :id", nativeQuery = true)
List<String> findInfoById(#Param("id") int id); // here you can return result as list
Change the return type in "public Ksiazka find" as list
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public List<Ksiazka> find(#RequestParam("id") int id){
}
Inside body try to do get result as list ,
#RestController
#RequestMapping("/api/osoba")
public class APIController {
#Autowired
private KsiazkaRepo ksiazkaRepo;
#JsonView(OnlyName.class)
#RequestMapping(method = RequestMethod.POST, value = "/getAll")
public List<Ksiazka> find(#RequestParam("id") int id){
List<String> autor = ksiazkaRepo.findInfoById(id); // get result as as list
List<Ksiazka> ksiazkaList = new ArrayList<>(); // create list from Ksiazka
for (String autors : autor) { // returned result you can loop
Ksiazka ksiazka = new Ksiazka(); // create Object to Ksiazka
ksiazka.setAutor(autors);
ksiazkaList.add(ksiazka); //add created object to List
}
return ksiazkaList; // return your list
}

How should I design this addOrders method?

If you are using Spring Data then you will need to create a CrudRepository for each table you which to access. The CrudRepository allows you to easily manipulate data in your table using standard ORM practices. Here is a link with more details.
For more detailed info on how to use Spring Data check out this wonderful guide. This guide has become indispensable when working with Spring Data.

There are many options to this but i have used below approach so hope it helps you. The #Query annotation allows to execute native queries by setting the nativeQuery flag to true.
#Query(value = "select o.* from customer c inner join order o on c.customer_id = o.customer_id where o. = ?1", nativeQuery = true)
Please write sql according to your requirement.

How to call native query for spring repository(Join three tables and tables haven't any relationship)

I have three tables which called SLSNotification,SLSWorkflow and Importer These tables are not any relationships... I want to get three tables for jasper report.. So I create a native query for it.. It works fine on MySQL... But when i add it to the SLSWorkflowRepository retrieve only workflow class only.. I want to get other classes also from this repository... I think it retrieves only because i write this like this
#Query(value = "select * from slsnotification a join sls_wrkflw b on a.snumber = b.snumber join importers c on c.importer_vat_number = a.importervat where a.importervat = :importerVatNumber and a.snumber = :snumber", nativeQuery = true)
Object getForPrint(#Param("snumber") Long snumber,#Param("importerVatNumber") String importerVatNumber);
can i get other classes for SLSIWorkflow getForPrint() methord...
If i wrong please give some onother way...

How to connect three tables... Please help me someone...

You are getting a SLSIWorkflow only because you are returning that Entity only in the following code in WorkflowServices.
public SLSIWorkflow getApplicationForPrint(Long SNumber, String importerVatNumber) {
return workflowRepository.getForPrint(SNumber, importerVatNumber);
}
If you return an Object it will have all the fields from tables slsnotification, sls_wrkflw, importers as a Object[].
Plus using a Plain JOIN it will result in an INNER JOIN by default. This will not return anything if one joined table doesn't satisfy the ON criteria. It is good if you use LEFT JOIN so that the null will be returned.

Deleting child entity from set in parent class

I am trying to attach image files to an entity called product. I can create a product along with the image pretty well but when i try to delete an image i get the following error.
HTTP 500 - Request processing failed; nested exception is org.hibernate.PersistentObjectException: detached entity passed to persist: com.IJM.model.Product

}
public void setDirectory(Directory directory) {

}
And this is the code for the controller calling the deleting method
#RestController
#RequestMapping("/image")
public class ImageController {
#Autowired
ProductService productService;
#Autowired
ImageService imageService;
private static final String productImagePath="C:\\IJM\\Images\\Product\\";
#RequestMapping(value = "/product/{code}", method = RequestMethod.DELETE)
public ResponseEntity<Image> deleteProductImage(#PathVariable("code") String code) {
System.out.println("Fetching & Deleting Image for product " + code);
code = code.toUpperCase();
if (!productService.isProductExist(code)) {
System.out.println("Product with code " + code + " not found");
return new ResponseEntity<Image>(HttpStatus.NOT_FOUND);
}
else
{
Product product = productService.findProductByCode(code);
if(product.getImages()!=null)
{
for(Image image:product.getImages())
{
product.getImages().remove(image);
image.setProduct(null);
imageService.deleteImage(image.getId());
}
productService.saveProduct(product);
try{
File file = new File(productImagePath+code);
if(FileDeleter.removeDirectory(file)){
System.out.println(file.getName() + " is deleted!");
}else{
System.out.println("Delete operation is failed.");
}
}catch(Exception e){
e.printStackTrace();
}
}
}
return new ResponseEntity<Image>(HttpStatus.NO_CONTENT);
}
}
In case someone else is wondering.. the service just calls the DAO
#Override
public void deleteImage(long id) {
Image image = imageDao.findById(id);
imageDao.delete(image);
}
This is the Dao Class
#Repository("imageDao")
public class ImageDaoImpl extends AbstractDao<Long,Image> implements ImageDao{
#Override
public void delete(Image image) {
super.delete(image);
}
}
This is the code in my abstract DAO class
public void delete(T entity) {
getSession().delete(entity);
}

It seems these line are not in proper order.
product.getImages().remove(image);
image.setProduct(null);
imageService.deleteImage(image.getId());
Also not sure what imageService.deleteImage(image.getId()); is doing. It is not required.
Please try like below.
for(Image image:product.getImages())
{
image.setProduct(null);
product.getImages().remove(image);
}
productService.saveProduct(product);
This should be enough. I know it doesn't make any sense to change the order but It had worked for me.
