Spring Boot w/ JPA: move @Entity to different package

Question

I'm having trouble with my first steps using Spring-Boot with JPA. I've started with a pretty minimalistic example from Git using Gradle.

Now simply moving Customer to another package, let's say to hello2 results in an exception Caused by: java.lang.IllegalArgumentException: Not an managed type: class hello2.Customer. I tried to add

@ComponentScan(basePackageClasses= {Customer.class}) // AND OR @EnableJpaRepositories(basePackageClasses= {Customer.class})

to Application, but without success.

What am I doing wrong?

Location of entities in Spring Boot can be configured using @EntityScan.

By default, @EnableAutoConfiguration enables entity scanning in the package where it's placed (if it's not a default package).

This is a couple years later, but i am also getting this same thing. Tried every possible config i can think of but am still getting "not a managed type" put @EnableAutoConfiguration and @EntityScan("my package") in my repository configuration and still get this error. – wondergoat77 Jul 24 '17 at 15:24

You must locate entities and repositories pakages by using

@EnableJpaRepositories(basePackages = "your.repositories.pakage")

@EntityScan(basePackages = "your.entities.pakage")

I was missing @EntityScan, my entities and my repos are in different packages. You can alternatively use @EntityScan(basePackageClasses = AClassInPackageWhereAllEntitiesAre.class) Thanks! – Toguard Oct 25 '15 at 09:24

this is what worked for me :

@EnableJpaRepositories(basePackages ={ "package1","package2"})
@EntityScan(basePackages ={ "package3","package4"})

Giving same package location (i.e base package) for below annotation worked for me :-

@SpringBootApplication(scanBasePackages = {"org.ashu.java.*"})
@EnableJpaRepositories(basePackages ={ "org.ashu.java.*"})    
@EntityScan(basePackages ={ "org.ashu.java.*"})
