Spring Boot: The managed version is 1.3.2.RELEASE The artifact is managed in org.springframework.boot:spring-boot-dependencies:1.3.2.RELEASE

Question

I create a skeleton application use Spring boot. This is my pom.xml

I stuck at this step:

Spring Boot: The managed version is 1.3.2.RELEASE The artifact is managed in org.springframework.boot:spring-boot-dependencies:1.3.2.RELEASE

When I try add Hiberante 5.1.0.Final manually, this notice appear:

Overriding managed version 4.3.11.Final for hibernate-core

Help me resolve these problem.

Answer 1

Spring Boot provides dependency management for Hibernate. The warning is Eclipse telling you that you've overridden this dependency management by declaring a version directly on a dependency. That's a risky thing to do as you may end up with a mixture of Hibernate versions on the classpath. In fact, looking at your pom, you've overridden the version of hibernate-core but not of hibernate-entitymanager. This means you'll have 5.1.0.Final of the former and 4.3.11.Final of the latter on the classpath. That will almost certainly lead to problems at runtime.

A safer way to use Hibernate 5 is to override Boot's dependency management. As you are using spring-boot-starter-parent as your pom's parent you can do that by overriding the hibernate.version property:

<properties>
    <hibernate.version>5.1.0.Final</hibernate.version>
</properties>

This will ensure that all Hibernate modules for which Spring Boot provides dependency management will have the desired version.

Finally, a note of caution. Hibernate 5.1 is very new and contains some breaking changes, even from 5.0.x. As a result, you may run into some incompatibility problems. If you don't want to be right on the bleeding edge, 5.0.x may be a safer choice. It will become the default Hibernate version in Spring Boot 1.4.

Answer 2

Spring Boot automatically defines version for dependencies as listed in this appendix. http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#appendix-dependency-versions

Eclipse is just reminding about it. You can ignore the warning if you really want to change the version for that dependency.
