Spring Data JPA - Consider defining a bean named 'entityManagerFactory' in your configuration

Question

I am developing an application in Spring, using Tomcat, Mysql5, Java8... The problem is that I cannot deploy it, due to "required bean 'entityManagerFactory' not found" problem. I have developed this project with my coworkers but they can perfectly deploy it with any problems, even if I copy-paste the same project in Spring Tool Suite. How can be possible? Error:

Answer 1

In my case, i had wrong dependency: spring-data-jpa. when i changed to spring-boot-starter-data-jpa, it solved the problem. i didn't have to add any annotation @Repository nor @EnableJpa etc.
