Hi Ivan,<br>
<br>
JPAFacet depends on having a PersistenceCommonDescriptor
(<a href="https://github.com/forge/core/blob/master/javaee/api/src/main/java/org/jboss/forge/addon/javaee/jpa/JPAFacet.java#L27" target="_blank">https://github.com/forge/core/blob/master/javaee/api/src/main/java/org/jboss/forge/addon/javaee/jpa/JPAFacet.java#L27</a>),
so I guess that extending JPAFacet is not a good idea in this case.
Is it a problem if the persistence.xml is created for a Spring Boot
project?<br>
<br>
Otherwise, I'd suggest you to create the SpringBootJPAFacet without
reusing the JavaEE ones (and create a "Spring Boot: JPA Setup"), as
they really don't follow JavaEE in this context beyond the JPA JARs.<br>
<br>
Best Regards,<br>

<div dir="ltr">Hi folks,
<div><br>
</div>
<div>As some of you probably heard, in Bulgarian JUG we are
going to adopt an addon (as George put it a couple of months
ago). Beginning of August we are going to develop a Forge
extension for Spring Boot. One of the things that we are not
sure yet how to tackle is persistence.</div>
<div><br>
</div>
<div>You see, Spring supports JPA. However instead of
configuring it in the Java EE way with persistence.xml, in
Spring Boot they use a properties file for that (and for all
their configuration). The current JPA facet implementations
however are developed with presistence.xml in mind. The JPA
setup wizard itself is also bound somehow to presistence.xml -
it picks the facet to install based on that file.</div>
<div><br>
</div>
<div>What we want to do is not to rewrite all the Forge commands
for JPA just because of the fact above. We were thinking of a
small change - <span style="font-size:12.8000001907349px">extend
JPAFacet with SpringBootJPAFacet. And then add a new
implementation of PersistenceContainer ->
SpringBootContainer or something? And then we have to change
JPASetupWizardImpl to pick the facet not only based on the
JPA version, but also based on the container. </span></div>
<div><span style="font-size:12.8000001907349px"><br>
</span></div>
<div><span style="font-size:12.8000001907349px">Or maybe there
is a better way?</span></div>
<div><br>
</div>
<div>I am expecting your feedback :)</div>

<div>Cheers,</div>
