My application originally used only Hibernate and everything worked fine, but with Spring i'm getting an exception. It feels like Spring causes different behavior for Hibernate.
So with Spring & Hibernate i get this exception trace:
Stack trace photo_1
Stack trace photo_2

Only difference is when i start application with Spring, i dont get these exceptions when i dont use Spring.
I think the issue is from the fact that you setter is private and should be public
private void setLink(String link) {
this.link = link;
}
Should be
public void setLink(String link) {
this.link = link;
}
Same for setVersion and setDepth
I found out, I commented these maven dependencies

And everything started working... I guess devtools are the reason, dont want to check, I tried so many other stuff, and this is the reason...

Then I thought that it could be a problem with the controller that is not returning data or redirecting correctly but I can't think of what it could be
My controller
#RestController
public class PruebaController {
#Autowired
private PersonaService personaService;
#GetMapping(value="/index",produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> index(){
return ResponseEntity.ok(this.personaService.findAll());
}
}
The problem is that when I do the command -> "spring-boot:run" and go to the link I get -> Error 404
I am also sure that the connection to the database is made perfectly so I only have to rule out that the service is done wrong but I don't know what it could be
PersonaService.java
public interface PersonaService {
Page<PersonaDTO> findAll();
PersonaDTO findByNSS(String NSS);
PersonaDTO findByNumTarjeta(String numTarjeta);
void save(PersonaDTO paciente);
void saveAll(List<PersonaDTO> pacientes);
void deleteById(Long id);
}
and this is my file
PersonaImpl.java
package Services.Implementation;
import DTO.PersonaDTO;
import Repository.PersonaRepository;
import Services.Interfaces.PersonaService;
import Utils.MHelpers;
import com.example.demo.Persona;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.List;
import java.util.Optional;
#Component
public class PersonaImpl implements PersonaService {
#Autowired
private PersonaRepository PersonaRepository;
#Override
public Page<PersonaDTO> findAll() {
Page<Persona> personas = this.PersonaRepository.findAll();
return personas.map(this::convertToPersonaDTO);
}
#Override
public PersonaDTO findByNSS(String NSS) {
Optional<Persona> personas = this.PersonaRepository.findByNSS(NSS);
if (!personas.isPresent()){
return null;
}
return MHelpers.modelMapper().map(personas.get(),PersonaDTO.class);
}
#Override
public PersonaDTO findByNumTarjeta(String numTarjeta) {
Optional<Persona> personas = this.PersonaRepository.findByNumTarjeta(numTarjeta);
if (!personas.isPresent()){
return null;
}
return MHelpers.modelMapper().map(personas.get(),PersonaDTO.class);
}
#Override
public void save(PersonaDTO personaDTO) {
Persona persona = MHelpers.modelMapper().map(personaDTO, Persona.class);
this.PersonaRepository.save(persona);
}
#Override
public void saveAll(List<PersonaDTO> personas) {
List<Persona> p = new ArrayList<>();
for (PersonaDTO persona: personas) {
Persona pers = MHelpers.modelMapper().map(persona,Persona.class);
p.add(pers);
}
this.PersonaRepository.saveAll(p);
}
#Override
public void deleteById(Long id) {
this.PersonaRepository.deleteById(id);
}
private PersonaDTO convertToPersonaDTO(final Persona persona){
return MHelpers.modelMapper().map(persona,PersonaDTO.class);
}
}
If you need more information tell me
I'm doing a CRUD for a collection named Schema and need to retrieve de _id as a hexadecimal string, but when i use the collection.find() i get the timestamp and date instead of the string.
I'm receving this structure:
{
"_id": {
"timestamp": 1604689898,
"date": "2020-11-06T19:11:38.000+00:00"
}
}
But i need something like this:
{
"_id": "5fa5a085a4b09b307d53ed57"
}

The problem you face is ObjectId becomes extended (Deserialized). we make it serialization.Add this dependency in pom
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.0.rc1</version>
</dependency>
Add the following method in main class.
#Bean
public Jackson2ObjectMapperBuilderCustomizer customizer()
{
return builder -> builder.serializerByType(ObjectId.class,new ToStringSerializer());
}
This will give you expected output.
In my case, using Kotlin it was so simple as to add a Jackson JSON serializer:
#JsonSerialize(using = ToStringSerializer::class)
val id: ObjectId = ObjectId.get(),
In order to get:
{
"id": "622b34af87c70514f6452363",
...
}
instead of:
{
"id": {
"timestamp": 1646998703,
"date": "2022-03-11T11:38:23.000+00:00"
},
...
}

What's the issue here and how do I solve it?
Change your jasper dependency as
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
The dependency should be configured as with scope provided:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
I created a new Maven project , I installed JBoss tools in Eclipse Kepler (including Hibernate) and I wanted to test a Hibernate program so I did this program below, but when I run as Java program I get errors / exceptions.
Here are my files :
File SaveStudent.java :
package com.hibernate.demo;
import com.hibernate.entity.student;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class SaveStudent {
public static void main(String[] args) {
SessionFactory f = new Configuration()
.configure("hibernate.cfg.xml")
.addAnnotatedClass(student.class)
.buildSessionFactory();
Session session = f.getCurrentSession();
try {
System.out.println("Creating student...");
student st = new student("X","X","xx#xx.xx");
session.getTransaction();
System.out.println("Saving ...");
session.save(st);
session.getTransaction().commit();
System.out.println("Done!!!");
} finally {
session.close();
f.close();
}
}
}
File student.java :
package com.hibernate.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="hbstudent")
public class student {
#Id
#Column(name="id")
private int id;
#Column(name="first")
private String firstname;
#Column(name="last")
private String lastname;
#Column(name="email")
private String email;
public student (){
}
public student(String firstname, String lastname, String email) {
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Override
public String toString() {
return "student [id=" + id + ", firstname=" + firstname + ", lastname="

}
}

I'm trying to return xml from my #RestController method -
#RestController
public class MCSController {
.
.
#RequestMapping(value = "/encoders", method = { RequestMethod.GET }, produces = { MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
public List<EncoderVO> getEncoders() {
List<EncoderVO> encoders = null;
try {
encoders = infoService.listEncoders();
} catch (MCSException e) {
logger.error("Error in listing encoders : " + e.getMessage());
}
return encoders;
}
Here is my EncoderVO.java -
#XmlRootElement
public class EncoderVO {
#XmlElement
private Long id;
#XmlElement
private String name;
#XmlElement
private Boolean flagActive;
public EncoderVO() {
}
public EncoderVO(Long id, String name, Boolean flagActive) {
super();
this.id = id;
this.name = name;
this.flagActive = flagActive;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Boolean getFlagActive() {
return flagActive;

public void setFlagActive(Boolean flagActive) {

When I hit the url /encoders in browser, i get the below error -
There was an unexpected error (type=Not Acceptable, status=406). Could
not find acceptable representation
The jackson related jars in my calsspath are -
jackson-core-asl : 1.9.13
jackson-jaxrs : 1.9.13
jackson-mapper-asl : 1.9.13
jackson-annotations : 2.6.3
jackson-core : 2.6.3
jackson-module-jaxb-annotations : 2.2.3
jackson-jaxrs-json-provider : 2.2.3
jackson-jaxrs-base : 2.5.4
jackson-databind : 2.6.3
So, I have MappingJackson2HttpMessageConverter in my classpath.
Please suggest. Thanks in advance.
There is a solution that will work out-of-the-box, similarly to JAX-RS but with a bit worse output. The solution uses jackson-dataformat-xml. Add dependency to your project:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
Response will look like this:
<?xml version="1.0" encoding="UTF-8"?>
<List>
<item>
<id>1</id>
<name>testEncoder1</name>
<flagActive>true</flagActive>
</item>
<item>
<id>2</id>
<name>testEncoder2</name>
<flagActive>true</flagActive>
</item>
<item>
<id>3</id>
<name>testEncoder3</name>
<flagActive>true</flagActive>
</item>
</List>
For further details please look at Spring MVC Way (jackson-dataformat-xml)
try
http://localhost:8080/mcs-0.0.1-SNAPSHOT/encoders.
mcs is the name of the application and
0.0.1-SNAPSHOT the version.
If it doesn't works you have to add a global path into the RequestController. Something like:
#RestController
#RequestMapping(value = "/mcs")
public class MCSController {
.
.
#RequestMapping(value = "/encoders", method = { RequestMethod.GET }, produces = { MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
public List<EncoderVO> getEncoders() {
and this request:
http://localhost:8080/mcs-0.0.1-SNAPSHOT/mcs/encoders
i hope it helps you.
Cheers
Add this dependecy in you POM.xml
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.8</version>
problem is with version of this jar. so please try out this solution
