I have an application created in Spring Boot https://github.com/JonkiPro/REST-Web-Services. I need to replace Hibernate provider with EclipseLink.The problem is that practically the entire configuration is found only in the application. properties https://github.com/JonkiPro/REST-Web-Services/blob/master/web/src/main/resources/application.yml file and I don't know what to change to EclipseLink.
There is an example project from Spring on how to use Spring Boot with EclipseLink. Please refer:

is it possible to create database schema using spring boot with JPA in postgresql through java coding? like we are creating tables using spring boot with JPA.
Yes you can do. Please refer the Spring Documentation.
Database Initialization
I'm working on project, that uses Spring framework (Spring MVC, JDBC etc.) Project is not so big and uses Jetty servlet container, PostgreSQL database with standard DAO classes(sql requests). I need to make it possible to use Spring Boot and Hibernate/Spring JPA with repositories instead SQL queries. I found a few states describes migration to spring boot: https://www.baeldung.com/spring-boot-migration https://3ldn.nl/2016/02/16/spring-boot-in-an-existing-application-part-1/ Now I make small example with Hibernate - generate few Entities and make CRUD operations with Hibernate instead sql queries.
But I need to update existing project for using Spring Boot and I need to use Spring JPA Repositories.
I add spring boot dependencies in dependencyManagment section. What steps I need to do`s next?
I've solved my task and succesfully migrate project to spring boot with JPA/Hibernate.
Its very simple task! and all what you need to migrate is:
0) solve all dependencies issues and remove all tags from boot dependencies.
1) How to use JPA Repositories without Spring Boot
2) How to migrate existing Spring project to Spring Boot
that is all.
I searching too much for my question in www.stackoverflow.com, but nothing helps me.so I have to post my question.
I have completed my project in spring 4 + Hibernate with MongoDB. now client requirement is MySQL. so I have to switch that project in Hibernate with MySQL.
I have tried to write code in the project. but it shows to much error in session as NullPointerException and another about my service and repository related.
so can you suggest any demo for a Hibernate with MySQL configuration in spring MVC 4.? and yes which configuration is good? XML based or java class based?
Please follow the link, it would help you to get start with Spring MVC + Hibernate (MySQL).
https://examples.javacodegeeks.com/enterprise-java/spring/mvc/spring-mvc-hibernate-tutorial/
About configuration: I personally prefer Java based configuration (not XML)
For xml configuration please have a look at:
http://www.codejava.net/frameworks/spring/spring-4-and-hibernate-4-integration-tutorial-part-1-xml-configuration
You should use Spring Boot instead of Spring MVC 4. Spring Boot will help you a lot as not too many configuration. You can easily switch to this without too much changes. No persisting of entity need to write as you can use Spring Data JPA for that.
You can following Spring Boot + Hibernate example by StartWithJava.

I am using spring boot in my application, i want to know how to use Spring boot, iBatis and MySQL. While i am trying to find the reference for Spring boot with iBatis projects its automatically redirect to myBatis. I need a example project or site for referring this. I have example for mybatis but i want ibatis with spring boot.
I think, you shouldn't think how you may connect them. Just read docs about iBatis(MyBatis). But the following link special for you http://www.mybatis.org/spring-boot-starter/mybatis-spring-boot-autoconfigure/
I have spring boot project which has dependencies on rest web service, mysql, jdbc and JPA. How do i reverse engineer the database tables and create dao's for those tables using Spring Eclipse sts? I believe it can be done using Spring roo, but can it be done without using Spring roo and by just using Spring eclipse STS.
I didn't find any built in option to reverse engineer the database in spring boot, but the below telosys-tools plugin worked out for me.

Not sure why Spring STS tool doesn't have some thing similar.
