Question

I have recently learning Spring to be specific Spring ORM. I am getting some errors from my code, I am not getting where I am going wrong though i have all instruction of the tutorial.

Here are java and configuration files:

com.spring.orm.Main.java file

package com.spring.orm;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.spring.orm.dao.StudentDao;
import com.spring.orm.entities.Student;

public class Main 
{
    private static ApplicationContext context;

    public static void main( String[] args )
    {
        
        context = new ClassPathXmlApplicationContext("XML/config.xml");
        StudentDao obj1 = context.getBean("studentDao",StudentDao.class);
        
        Student s1 = new Student(1,"Sudheer Mishra","Surat");
        
        int insert = obj1.insert(s1);
        if(insert > 0) {
            System.out.println("data successfully inserted");
        }System.out.println("something went wrong");
        
    }
}

com.spring.orm.entities.Student.java file



package com.spring.orm.entities;

import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.Table;

@Entity
@Table(name = "student_details")
public class Student {

    @Id
    @Column(name = "studentId")
    private int studentId;

    @Column(name = "studentName")
    private String studentName;

    @Column(name = "studentCity")
    private String studentCity;

    public Student() {
        super();
    }

    public Student(int studentId, String studentName, String studentCity) {
        super();
        this.studentId = studentId;
        this.studentName = studentName;
        this.studentCity = studentCity;
    }

    public int getStudentId() {
        return studentId;
    }

    public void setStudentId(int studentId) {
        this.studentId = studentId;
    }

    public String getStudentName() {
        return studentName;
    }

    public void setStudentName(String studentName) {
        this.studentName = studentName;
    }

    public String getStudentCity() {
        return studentCity;
    }

    public void setStudentCity(String studentCity) {
        this.studentCity = studentCity;
    }

}

com.spring.orm.dao.StudentDao.java file

package com.spring.orm.dao;

import org.springframework.orm.hibernate5.HibernateTemplate;

import com.spring.orm.entities.Student;

import jakarta.transaction.Transactional;

public class StudentDao {
    
    private HibernateTemplate hibernateTemplate;
    
    @Transactional
    public int insert(Student student) {
        int i = (int) this.hibernateTemplate.save(student);
        /* HibernateTemplate has all the CRUD operation methods */
        return i;
    }

    public HibernateTemplate getHibernateTemplate() {
        return hibernateTemplate;
    }

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }
    
}

config.xml (which i have kept in src/main/resources/XML folder)

When I am running my Main.java I’m getting on my console

I had checked what I can but not able to come up with this error, not getting that what I am missing here.

Is there any jars which I have not added ? or another configuration is still pending..

If anyone have any idea please help.

Eclipse Version: 2023-09 (4.29.0)

Build id: 20230907-1323

Thank you

If anyone have any idea, I’ll be grateful for their help. I’m getting that what I am missing here any jars or configuration of my entities. But I have followed exact same path as the tutorial. But still getting this error on console.
