New issue 547 by mingfai.ma: Provide a JpaPersistModule constructor with
the properties argument
http://code.google.com/p/google-guice/issues/detail?id=547
I'm using the nightly build with guice-persist.
could JpaPersistModule allow us to set the "properties" field by providing
a constructor as follows:
public final class JpaPersistModule extends PersistModule {
...
public JpaPersistModule(String jpaUnit, Properties properties) {
Preconditions.checkArgument(null != jpaUnit && !jpaUnit.isEmpty(),
"JPA unit name must be a non-empty string.");
this.jpaUnit = jpaUnit;
this.properties = properties;
}
...
}
Let's say we have a data project that other app projects will depend on it.
Ideally, only the data project has the persistence.xml and any JPA
configurations. And the data project will provide a module that install the
JpaPersistModule and expose Dao/EntityManager etc. to other projects.
The first problem is, it seems I have to put a persistence.xml in every
project to work. There might be a better way but I won't tackle this
problem for now.
Assume I'll put persistence.xml in every app project, I don't want to
duplication the JPA properties like jdbc url, user, password etc. If the
JpaPersistModule provides a 2nd constructor, it could fix this problem.
thanks
