Hi,
I've created a new class:
public class CustomMongoMapEntityStoreAssembler extends
Assemblers.VisibilityIdentityConfig<CustomMongoMapEntityStoreAssembler>
{
@Override
public void assemble(ModuleAssembly module) throws AssemblyException
{
module.services(UuidIdentityGeneratorService.class)
.visibleIn(visibility());
ServiceDeclaration service =
module.services(MongoMapEntityStoreService.class)
.withConcerns(MongoEntityStoreConfigurationConcern.class)
.visibleIn(visibility());
if (hasIdentity()) {
service.identifiedBy(identity());
}
if (hasConfig()) {
configModule().entities(MongoEntityStoreConfiguration.class)
.visibleIn(configVisibility());
}
}
}
and then a concern as you suggest:
public abstract class MongoEntityStoreConfigurationConcern
extends ConcernOf<Configuration<MongoEntityStoreConfiguration>>
implements Configuration<MongoEntityStoreConfiguration>
{
@Override
public MongoEntityStoreConfiguration get()
{
try {
MongoEntityStoreConfiguration conf = next.get();
List<ServerAddress> serverAddresses = new ArrayList<>();
serverAddresses.add(new ServerAddress("1.1.1.5", 27017));
serverAddresses.add(new ServerAddress("1.1.1.6", 27017));
serverAddresses.add(new ServerAddress("1.1.1.7", 27017));
conf.nodes()
.set(serverAddresses);
return conf;
}
catch (UnknownHostException err) {
throw new RuntimeException(err);
}
}
}
and I called it as:
new
CustomMongoMapEntityStoreAssembler().withConfig(configModule,
Visibility.application)
.visibleIn(Visibility.application)
.identifiedBy("mongodb.booking.store")
.assemble(module);
But then I get back the following error:

Yes, the registration of values(ServerAddress.class) should not be there.
That was an oversight on my behalf.
A few things that could be a work-around.
1. Create a Concern that intercepts the configuration and populates the
nodes. You add the Concern in your own Assembler (copy source from
MongoDbEntityStoreAssembler), so instead of;
ServiceDeclaration service = module
.services( MongoMapEntityStoreService.class )
.visibleIn( visibility() );
add the Concern as;
ServiceDeclaration service = module
.services( MongoMapEntityStoreService.class )
.withConcerns( MyConfigurationConcern.class )
.visibleIn( visibility() );
Then your MyConfigurationConcern would be something like;
public abstract class MyConfigurationConcern extends
ConcernOf<Configuration<MongoEntityStoreConfiguration>>
implements Configuration<MongoEntityStoreConfiguration>
{
@Override
public MongoEntityStoreConfiguration get()
{
MongoEntityStoreConfiguration conf = next.get();
conf.nodes().set( MY_NODES );
return conf;
}
}
2. Maybe you want your own Configuration store. Create (or use) an Entity
Store that does not require any Polygene Configuration, and drop that into
the Configuration Module. Perhaps read configuration from "Java
Preferences", maybe a configured Zookeeper cluster or maybe ETCD. And if
the configuration entity store is populated, then there will be no fallback
to properties/yaml files.
This is of course a fairly advanced option, but I would recommend it for
production setup.
But I am sure Paul will say; "Just ..." :-)
Cheers
