I'm new using this framework, I'm tryng to deploy a web with a hibernate connection, I created a .xml config file to connect to PostgreSQL.
But the logs shows this error:

There are some code that are some at my clases in this proyect the other intermedial clases are similar, I'm trynt in this moment insert some objects to the database.
Thanks to your help in advance.
Have you tried to add a Configuration Class in your project for example
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories( basePackages = "your repository package" )
#EntityScan( basePackages = {"your entity package1","your entity package2"}
public class TransactionConfiguration {}
This will help you to find your entity classes in the project.

That's my first project with Spring Boot implemented. I tried going step by step with official Spring tutorial but I'm stuck with a problem that I can't find any answer about.
Whenever I try to call findAll() or find() method on my repository it returns empty array [].
Even with manual preloading enitites like done in tutorial and immediately trying to display database content I get the same result.
I can guess I'm missing something silly, but I can't figure it out for some hours now. What's the cause? Tomcat/jpa/spring version mismatch? Missing annotation somewhere?
Here's my AnimalRepository.java
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface AnimalRepository extends JpaRepository<Animal, Long> {
}
LoadDatabase.java
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.Transactional;
#Configuration
class LoadDatabase {
private static final Logger log = LoggerFactory.getLogger(LoadDatabase.class);
#Bean
CommandLineRunner initDatabase(AnimalRepository repository) {
return args -> {
log.info("Preloading " + repository.save(new Lion("Bilbo")));
log.info("Preloading " + repository.save(new Lion("Frodo")));
log.info(repository.findAll().toString()); //try to log content to console
};
}
}
The logging above basically ends up with this console output:
logging result
Probably not as important, but AnimalController.java
import org.springframework.web.bind.annotation.*;
import java.util.List;
#RestController
public class AnimalController {
private final AnimalRepository repository;
AnimalController(AnimalRepository repository) {
this.repository = repository;
}
#GetMapping("/animals")
List<Animal> all() {
repository.save(new Lion("Bilbo")); //this doesn't work either
return repository.findAll();
}
#PostMapping("/animals")
Animal newAnimal(#RequestBody Animal newAnimal) {
return repository.save(newAnimal);
}
#GetMapping("/animals/{id}")
Animal one(#PathVariable Long id) {
return repository.findById(id)
.orElseThrow(() -> new AnimalNotFoundException(id));
}
#PutMapping("/animals/{id}")
Animal replaceAnimal(#RequestBody Animal newAnimal, #PathVariable Long id) {
return repository.findById(id)
.map(animal -> {
animal.setName(newAnimal.getName());
animal.setSpecies(newAnimal.getSpecies());
return repository.save(animal);
})
.orElseGet(() -> {
newAnimal.setId(id);
return repository.save(newAnimal);
});
}
#DeleteMapping("/animals/{id}")
void deleteAnimal(#PathVariable Long id) {
repository.deleteById(id);
}
}
And the finally Lion.java
import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;
import java.util.Objects;
#Entity
public class Lion implements Animal {
private #Id
#GeneratedValue Long id;
private String name;
private String species;
private int requiredFood;
//private Zone zone;
public Lion(String name) {
this.name = name;
this.species = this.getClass().getSimpleName();
this.requiredFood = LION_REQUIRED_FOOD;
}
public Lion() {
}
#Override
public Long getId() {
return id;
}
#Override
public void setId(Long id) {
this.id = id;
}
#Override
public String getName() {
return name;
}
#Override
public void setName(String name) {
this.name = name;
}
#Override
public String getSpecies() {
return species;
}
#Override
public void setSpecies(String species) {
this.species = species;
}
#Override
public int getRequiredFood() {
return requiredFood;
}
#Override
public void setRequiredFood(int requiredFood) {
this.requiredFood = requiredFood;
}
#Override
public boolean equals(Object o) {
if (this == o)
return true;
if (!(o instanceof Animal animal))
return false;
return Objects.equals(this.id, animal.getId()) && Objects.equals(this.name, animal.getName())
&& Objects.equals(this.species, animal.getSpecies());
}
#Override
public int hashCode() {
return Objects.hash(this.id, this.name, this.species);
}
#Override
public String toString() {
return "Animal{" + "id=" + this.id + ", name='" + this.name + '\'' + ", species='" + this.species + '\'' + '}';
}
}
I tried switching JpaRepository to CrudRepository, but that didn't work out.
I think the problem here is that your data haven't been saved to the database, because of the transaction. try to change your repository.save() to repository.saveAndFlush()
cnv any one help me I dont knoe where make mistake,when i run my
application in chrome in browser when type
http://localhost:8100/currency-converter-feign/from/USD/to/INR/quantity/1000
i got this type of erro
This application has no explicit mapping for /error, so you are seeing
this as a fallback.

It is occurs due to mismatch of comumn name in your db table and in
your entity class. Because I use micriservices,I call some exchange
rates from another project by provideing its url in my repository, in
that project i privide same name in my entity class and in my db table
,but i declared diffrent name in my exchange service project. there i
declare conversationmultople and here declare convermultiple
.make sure both name same in db and your bean class
#EnableFeignClient service in your springboot main method
for example
package com.main;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;
#SpringBootApplication
#EnableFeignClients("com.main.serviceproxy")

and this is my table user (i use oracle 10g) :
can someone help me please ?
Check your Column definition, is it a Many to one or just a regular column?
#Column(name="EMPLOI")
private EmploiEntity emploi;
if it is your Emploi created right?
I am developing the backend part of a registration page for my website, the problem is that when I test this in postman I get the following error:
and I also get this error in my eclipse console:

I see that the error comes from the id but as you can see here I inserted the id in postman in the json part :
{
"id":2,

"ENTITE":2,
"LOGIN":"hr",
"MOTDEPASSE":"hr",
"NOM":"bougrine",
"PRENOM":"rachid",
"STATUT":"br",

this is my service interface :

this is my application.properties ( i change port 8080 to 8484 because a nother application use this port) :
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:#localhost:1521:XE
spring.datasource.username=nawfel
spring.datasource.password=hr
spring.jpa.show-sql=true
server.port=8484
and this is my table in oracle 10g :
I think the problem is that you are telling in your entity that id is a generated value. Doing so the value is removed by Jpa during insert. You have to change your strategy, if you are supplying the id you should not mark it as autogenerated.

I'm trying to develop a cross-platform application, with Cordova in the front-end and using Spring in the back_end.
Basically, I started by the link between the database and generating the classes (models). Here's my application properties:
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = updateUnable to find column with logical name: program_id
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager)
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
# Server
server.port=8080
endpoints.cors.allowed-origins=*
I wanted to try if I'm getting the list in JSON form before I go to the backend. So I made an example to get the list of operators, the class Operator is declared like that:

I added an interface (repository) implementing JpaRepository:

And as needed, also a controller for the class Operator:

#Autowired
private OperatorService operatorService;
#CrossOrigin
#RequestMapping(method = GET, value = "/operator/all")
public List<Operator> loadAll() {
return this.operatorService.findAll();
}
}
The interface service:
package com.rest.service;
import com.rest.model.Operator;
import java.util.List;
/**

public interface OperatorService {
List<Operator> findAll();

Then, I should go to localhost:8080/api/operator/all to get the list of operator as I used to do, but it's asking me to use a username password, I tried everything from db user (root, root) but doesn't work.
I don't even have a connexion page in the application.
enter image description here
If you have any idea, please feel free to suggest, I'm using a Mac as you see.
Thanks.
