How to use detailed SQL query on Srpingboot using #Query?

I'm having some trouble to find out how to use an specific query on Springboot
SELECT tb_excursao.fk_cliente, tb_cliente.nome, tb_cliente.documento, tb_cliente.org_emissor, tb_cliente.data_nascimento, tb_excursao.fk_viagem, tb_viagens.destino, tb_viagens.data_viagem
FROM ((tb_excursao
INNER JOIN tb_cliente ON fk_cliente = tb_cliente.id_cliente)
INNER JOIN tb_viagens ON fk_viagem = tb_viagens.id_viagem))
This works fine on MySQL, but the examples that I saw it's always something like "SELECT u FROM User u", and as a beginner I can't relate using columns from different tables using #Query.
The models are below:
Cliente.java
#Entity
#Table(name = "tb_cliente")
public class Cliente {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long idCliente;
#NotBlank
#Size(min = 3)
private String nome;
#NotNull
private String documento;
#NotNull
private String orgEmissor;
#NotBlank
#JsonFormat(pattern = "dd/MM/yyyy")
private Date dataNascimento;
#Temporal(TemporalType.TIMESTAMP)
private Date dataCadastro = new java.sql.Date(System.currentTimeMillis());
#OneToMany(mappedBy = "fkCliente")
Set<Excursao> excursao;
public long getIdCliente() {
return idCliente;
}
public void setIdCliente(long idCliente) {
this.idCliente = idCliente;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getDocumento() {
return documento;
}
public void setDocumento(String documento) {
this.documento = documento;
}

Viagem.java
#Entity

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.

And this is the code for the controller calling the deleting method
#RestController

public class ImageController {

#Autowired

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.

How to prevent endless loop in hibernate

I have a rest server and client which uses this API. I have a list of hotels and it had passed well until I added bidirectional dependencies to other entities.After that I start receive an endless array of entities which just repeat the same row in database.
It is my first project with hibernate so may be I made trivial mistakes of novice.

Could you please advise what is a way or ways to tell hibernate to stop this cycle?
p.s
This code contains another one issue. I f I remove one to one dependency and remain only one to many I receive failed to lazily initialize a collection of role: com.example.model.HotelsEntity.rooms, could not initialize proxy - no Session (through reference chain: java.util.ArrayList[0]->com.example.model.HotelsEntity["rooms"])

You need to mark entity as not serializable for JSON. Please use #JsonIgnore or #JsonIgnoreProperties("field") on one of the sides of the relations (the annotation is class-level).

Hibernate Update Parent Table and its Child Table , but not working porp?

Here i have two JPA Classes: TimeSheet and TimeSheetDetails
In this case i have a trouble with updation of timesheet, while updation the timesheet (master table) updated smoothly, but timesheet details (child table) generate new rows instead of updation and the link table also updated with the new values.....
Here what is the re

The problem is in this line:
obj.setTimesheetDetails(objTimeSheet.getTimesheetDetails());
You should do the same to update the child to what you are doing to update the parent. I.e:
obj.getTimesheetDetails().setTsd_Date(objTimeSheet.getTimesheetDetails().getTsd_Date);
