Failed to load ApplicationContext (Spring-boot/Repository)

I am trying to test a database class I've created but it's returning the error "Failed to load ApplicationContext..." How do I fix this?
package com.madi.StudentDataRestApi;
import static org.junit.jupiter.api.Assertions.assertEquals;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
#DataJpaTest
public class ControllerInputTest {
#Autowired
private MainController mainController;
#Autowired
private StudentRepo studentRepo;
#Test
void InputSearchTest() {
Student input = new Student(132123, "Example", "Anon", "CST", 7f);
mainController.addNewStud(input);
Iterable<Student> response = mainController.getStud(130267);
assertEquals(input, response);
}
}

For referred several other posts which stated versioning problem, but it didn't help.
I cannot find the problem with the code, can somebody help me?

I have analysed your code, Here are my findings.
Found some issues in BatchConfig class. You are using new JobBuilder(), new StepBuilder() while creating Job and Step. The right way is to use JobBuilderFactory, StepBuilderFactory.
I can see entity class (user) name is in lower, It should be in camelcase (User).
PS: I tested with PostgreSQL database using these properties but I am sure it will work with MySQL database as well
application.properties
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/batch_db

Unit Testing Javalin Framework, Mocking Context doesn't work

I'm using Javalin 4 and Mockito 4, and I want to test a simple controller method.
I was reading a tutorial in here : https://javalin.io/tutorials/testing
here is my controller :
package mhndev.controller;
import io.javalin.http.Context;
public final class CakeController
{
private CakeController() {}
static String[] cakes = {"Cheese", "Chocolate", "Carrot", "Banana"};
public static void getOneCake(Context ctx) {
for(String cake: cakes) {
if(cake.equals(ctx.pathParam("cake"))) {
ctx.result(cake);
return;
}
}
ctx.result("cake was not found!");
}
}
And this is my very simple test:
package mhndev;
import io.javalin.http.Context;
import mhndev.controller.CakeController;
import org.junit.jupiter.api.Test;
import static org.mockito.Mockito.*;
public class CakeControllerTest {
private final Context ctx = mock(Context.class);
#Test
public void GET_apple_cakes() {
when(ctx.pathParam("cake")).thenReturn("Banana");
CakeController.getOneCake(ctx);
verify(ctx, times(1)).pathParam("Banana");
}
}
And I received this error upon running the test :
java.lang.NullPointerException: Parameter specified as non-null is null: method io.javalin.http.util.ContextUtil.pathParamOrThrow, parameter pathParams
at io.javalin.http.util.ContextUtil.pathParamOrThrow(ContextUtil.kt)

It's like Context.pathParam method is really getting called, using mockito and mocking the context object shouldn't create a new object and not calling the real method from real object? Why this happens and How should I test?

Class cast error using spring and hibernate: com.w2e.model.Session cannot be cast to com.w2e.model.Session

I am using Spring and hibernate in a recent project and can't get around a class cast exception whenever I use stream() on a list of entities. I am not sure if it is an issue with spring, or if it is somehow related to hibernate interacting with spring. I am new with spring and hibernate so I'm not sure if there is something basic I am missing. Here is the error I am getting:

I am using the following entity:
package com.w2e.model;
import javax.persistence.*;
#Entity
#Table(name = "session")
public class Session{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long id;
#Column(name = "completions")
private int completions;
public Session(int completions){
this.completions=completions;
}
//For Hybernate
public Session(){}
public int getCompletions() {
return completions;
}
public void setCompletions(int completions) {
this.completions = completions;
}
public Long getId() {
return id;
}
}
Here is my service:
package com.w2e.services;
import com.w2e.model.Session;
import com.w2e.repository.SessionRepository;
import org.springframework.stereotype.Service;
import java.util.List;
import java.util.stream.Collectors;
import static java.util.Objects.requireNonNull;
#Service
public class SessionService {
private final SessionRepository sessionRepository;
public SessionService(SessionRepository sessionRepository) {
this.sessionRepository = requireNonNull(sessionRepository);
}
public List<Long> get(){
return sessionRepository.get().stream().map(Session::getId).collect(Collectors.toList());
}
}
the repository:
package com.w2e.repository;
import com.w2e.model.Session;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.stereotype.Repository;
import java.util.ArrayList;
import java.util.List;
#Repository
public class SessionRepository{
private final SessionFactory factory;
public SessionRepository(SessionFactory factory) {
this.factory=factory;
}
public List<Session> get() {
org.hibernate.Session session = factory.openSession();
Transaction tx = null;
List<Session> e = new ArrayList<>();
try {
tx = session.beginTransaction();
String query = "FROM Session";
e.addAll(session.createQuery(query, Session.class).getResultList());
} catch (HibernateException exp) {
if (tx!=null) tx.rollback();
exp.printStackTrace();
} finally {
session.close();
}
return e;
}
}
The rest controller:
package com.w2e.controllers;
import com.w2e.services.SessionService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
#CrossOrigin(origins = { "http://localhost:3000", "http://localhost:4200", "http://localhost:8081" })
#RestController
public class CourseResource {
#Autowired
private SessionService sessionService;
#GetMapping("/session")
public List<Long> getSession(#PathVariable long id) {
return sessionService.get();
}
}
I initialize hibernate and spring using:
#SpringBootApplication
public class SpringBootFullstackCrudFullStackWithMavenApplication {
public static SessionFactory factory;
public static void main(String[] args) {
try {
Configuration config = new Configuration()
.addAnnotatedClass(Session.class)
.configure("hibernate.cfg.xml");
factory = config.buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Failed to create sessionFactory object." + ex);
throw new ExceptionInInitializerError(ex);
}
SpringApplication.run(SpringBootFullstackCrudFullStackWithMavenApplication.class, args);
}
}

Probably changing the class name instead of using spring same name for Session object could help to identify the problem more easily.

NoSuchMethodError in running test case for rest services using junit and grizzle

I had a test case to test the jersey 2.x rest service.. But got NullPointerException.. Seems to me there is a jar issue between jsr311 and javax.ws.rs-api . I didn't find any jsr311 with any dependencies.. Not sure why the servlet is taking is refering jsr311.jar
Below are my code changes
HelloWorldServiceTest.java

public void testSingleNode() throws Exception {
