Yes you can do. Please refer the Spring Documentation.

I want to use SingleStore database with my Spring Boot Application which uses Spring Data JPA. How it can be achieved?
To leverage SingleStoreDB with Spring Boot, you would use the JDBC connectors for both technologies - Spring + SingleStore. If you are using some ORM style features, use the mysql dialect. If you run into issues you can raise them here, on the forum or to support if you're an active customer.
I would like to put data only when database does not exist on booting Spring boot.
How can I see that?
My application yaml has
...hbm2ddl.auto: update
so I want to see if hibernate did create tables or not in Java code.
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:
https://github.com/spring-projects/spring-data-examples/tree/master/jpa/eclipselink
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/
