Error message: Internal server error 500 sessionFactory

Time：10-13

so I am using IntelliJ and the code was running up until using @Autowired

Troubleshooting done:

I have copied Customer controller, CustomerDAO and CustomerDAOImpl from Chad to make sure the imports and spelling are alright

Copied over xml files too, checked my folder mappings

Unfortunately the issue persists, I have read some threads on issues between jar files but I was not able to resolve the issue

The main cause seems to be that sessionFactory is unable to initialize for a reason, which I cannot resolve by myself. Any help would be greatly appreciated.

CustomerDAO.java

package com.luv2code.springdemo.dao;

import java.util.List;

import com.luv2code.springdemo.entity.Customer;

public interface CustomerDAO {

    public List<Customer> getCustomers();

}

CustomerDAOImpl

package com.luv2code.springdemo.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.luv2code.springdemo.entity.Customer;

@Repository
public class CustomerDAOImpl implements CustomerDAO {

    // need to inject the session factory
    @Autowired
    private SessionFactory sessionFactory;

    @Override
    @Transactional
    public List<Customer> getCustomers() {

        // get the current hibernate session
        Session currentSession = sessionFactory.getCurrentSession();

        // create a query
        Query<Customer> theQuery = currentSession.createQuery("from Customer", Customer.class);

        // execute query and get result list
        List<Customer> customers = theQuery.getResultList();

        // return the results
        return customers;
    }

}

}

Now sorry for this is quite a bit of code, but I've honestly tried troubleshooting which led nowhere. Last time a similar issue was resolved by changing dependencies, but since I am not very familiar with them it is a bit troublesome to find an issue there.

Try to code like this: https://www.javaguides.net/2018/11/spring-mvc-5-hibernate-5-xml-based-configuration-example.html and mostly your error will be solved because this link has the same thing which you are doing

CodePudding user response：

I will assume that you have a collision with your dependencies, which means that you probably have a lib folder with some hibernate jars that are colliding with dependencies from your pom.xml What you need to do is to remove that lib folder completely because you already have all dependencies that you need in your pom.xml After that find your .m2 folder

Unix/Mac OS X – ~/. m2/repository.
Windows – C:\Users\{your-username}\. m2\repository.

Delete the content of it, import your project back into your IDE > Maven > Update, and simply run your project again.
