I faced the same problem.
I found the following solution to register the PersistFilter several times.
you can inject the session provider as follows.
@Inject @MyDataSourceOne
private Provider<Session> sessionProvider;
---
@Retention(RetentionPolicy.RUNTIME)
@Target({ FIELD, PARAMETER, METHOD })
@BindingAnnotation
public @interface MyDataSourceOne {}
@Retention(RetentionPolicy.RUNTIME)
@Target({ FIELD, PARAMETER, METHOD })
@BindingAnnotation
public @interface MyDataSourceTwo {}
public class MyDataSourceOnePersistModule extends PrivateModule {
public static final Key<PersistFilter> MY_DATA_SOURCE_ONE_FILTER_KEY =
Key.get(PersistFilter.class, MyDataSourceOne.class);
public void configure() {
final JpaPersistModule jpm = new
JpaPersistModule("myDataSourceOne");
jpm.properties(new Properties()); // some kinda bug without this
install(jpm);
bind(Session.class).annotatedWith(MyDataSourceOne.class).toProvider(MyDataSourceOneSessionProvider.class);
expose(Session.class).annotatedWith(MyDataSourceOne.class);
bind(MY_DATA_SOURCE_ONE_FILTER_KEY).to(PersistFilter.class);
expose(MY_DATA_SOURCE_ONE_FILTER_KEY);
}
}
public class MyDataSourceTwoPersistModule extends PrivateModule {
public static final Key<PersistFilter> MY_DATA_SOURCE_TWO_FILTER_KEY =
Key.get(PersistFilter.class, MyDataSourceTwo.class);
public void configure() {
final JpaPersistModule jpm = new
JpaPersistModule("myDataSourceTwo");
jpm.properties(new Properties()); // some kinda bug without this
install(jpm);
bind(Session.class).annotatedWith(MyDataSourceTwo.class).toProvider(MyDataSourceTwoSessionProvider.class);
expose(Session.class).annotatedWith(MyDataSourceTwo.class);
bind(MY_DATA_SOURCE_TWO_FILTER_KEY).to(PersistFilter.class);
expose(MY_DATA_SOURCE_TWO_FILTER_KEY);
}
}
public class WebModule extends ServletModule {
protected void configureServlets() {
install(new MyDataSourceOnePersistModule());
install(new MyDataSourceTwoPersistModule());
// more bindings
filter("/*").through(MyDataSourceOnePersistModule.MY_DATA_SOURCE_ONE_FILTER_KEY);
filter("/*").through(MyDataSourceTwoPersistModule.MY_DATA_SOURCE_TWO_FILTER_KEY);
}
}
