Re: JpaPersistModule, Hibernate and URL Variables

[Evan Ruff]

I mean, sure you could, but I don't like to put the business login in my 
Bootstrap too much. It just felt cleaner the way I did it. I have defaults, 
logging, failover, warnings etc if the environment isn't setup quite the 
way I think it should be.

 Hey guys, 

 So I'm actually just letting Guice Persist pull it straight out of 
 META-INF/persistence.xml file. 

 I'm wondering where I can either change the URL or set it explicitly, 
 while still using Guice Persist.

 thanks!

Re: JpaPersistModule, Hibernate and URL Variables

[Stephan Classen]

Can't you simply do the following??

public class MyModule extends ServletModule {
  protected void configureServlets() {
    install(new JpaPersistModule("myJpaUnit").setProperties(myProperties));
  }
}

I've got an embedded H2 database being used in an

The one issue I have is that the path of the
database file is set in my URL as:


jdbc:h2:file:./data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

which changes depending on how the application is

written in a location set by an environment
variable, so that I'd have:


jdbc:h2:file:*$APP_DB_PATH*/data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

I've tried several different forms and it doesn't

scl,

Thanks for the tip, this works as expected. JpaPersistModule is final 
(ARGH) but I created a static utility class with an install method that 
handles it. I build the database connection string using the env props and 
then I'm able to set it using the JpaPersistModule.properties(  prop )

Re: JpaPersistModule, Hibernate and URL Variables

[Stephan Classen]

Only way you can try to achieve this is the methode: 
JpaPersistModule.setProperties()
The properties passed in will be used to create the entity manager 
factory (see JpaPersistService.start())


Maybe you can overwrite the URL in the properties you pass.

Hey guys,

So I'm actually just letting Guice Persist pull it straight out of

I'm wondering where I can either change the URL or set it explicitly, while

Re: JpaPersistModule, Hibernate and URL Variables

[Sondre Bjornebekk]

If you always want to use h2, you could just simply build the string using 
https://docs.oracle.com/javase/8/docs/api/java/lang/System.html#getenv--?

If you wanted to inject different JPA providers, you could certainly use 
Guice for that (since you posted here) - I have a HibernateSessionFactory 
that provides a session per request like this:

@Provides
@RequestScoped
private Session provideSession() {



And then for my jUnit tests I have:

@Provides
@Singleton
private Session provideSession() {


in a

public class TestGuiceModule extends AbstractModule


Would that fit your use case?

Cheers,

-S-

Re: JpaPersistModule, Hibernate and URL Variables

[Stephan Classen]

When are you passing this string?
Is it part of you Giuce Module??

Could you read the environment variable before creating the string and 
than manually create the URL string?

I've got an embedded H2 database being used in an installed 
application to manage state of some objects. I'm using Hibernate as my 
JPA implementation and everything is working great. The one issue I 
have is that the path of the database file is set in my URL as:


jdbc:h2:file:./data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

which changes depending on how the application is executed. I'd like 
to have the database file be written in a location set by 
an environment variable, so that I'd have:


jdbc:h2:file:*$APP_DB_PATH*/data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

I've tried several different forms and it doesn't seem to be taking.

Has anyone encountered this and could give me a pointer on how to 
implement?


Thanks!

JpaPersistModule, Hibernate and URL Variables

[Evan Ruff]

Hey guys,

I've got what I think is a pretty straightforward task but I'm having a 
little issue figuring out where to attach in my code.

I've got an embedded H2 database being used in an installed application to 
manage state of some objects. I'm using Hibernate as my JPA implementation 
and everything is working great. The one issue I have is that the path of 
the database file is set in my URL as:

jdbc:h2:file:./data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

which changes depending on how the application is executed. I'd like to 
have the database file be written in a location set by an environment 
variable, so that I'd have:

jdbc:h2:file:*$APP_DB_PATH*
/data/application_db;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE;

I've tried several different forms and it doesn't seem to be taking. 

Has anyone encountered this and could give me a pointer on how to implement?

Thanks!

E
