Hello,
I wrote a simple application using In-Memory EntityStore and RdfIndexing.
Now I want to
switch over to SQL Index/Store but receive the following exception :
java.lang.IllegalStateException: java.lang.StackOverflowError

Looks like as a endless loop, but I;m not able to figure out the reason.
Here also the assembly code
that produce the above exception.
private void assembleInfrastructureLayer( LayerAssembly
infrastructureLayer )
throws AssemblyException
{
// 1.) SQL Indexing
ModuleAssembly indexingModule = infrastructureLayer.module(
"INFRASTRUCTURE-Indexing" );
indexingModule
.objects(
EntityStateSerializer.class,
EntityTypeSerializer.class );
ModuleAssembly config = indexingModule.layer().module( "config"
);
config.services( MemoryEntityStoreService.class ).visibleIn(
Visibility.module );
// EntityStore
indexingModule.services( MemoryEntityStoreService.class,
UuidIdentityGeneratorService.class ).visibleIn( Visibility.application );
// DataSourceService + Index/Query's DataSource
new DBCPDataSourceServiceAssembler(
"datasource-service-postgres",
Visibility.module,
config,
Visibility.layer ).assemble(
indexingModule );
DataSourceAssembler dsAssembler = new DataSourceAssembler(
"datasource-service-postgres",
"datasource-postgres",
Visibility.module,
DataSources.newDataSourceCircuitBreaker() );
// Index/Query
new PostgreSQLAssembler( Visibility.application, dsAssembler
).assemble( indexingModule );
config.entities( SQLConfiguration.class ).visibleIn(
Visibility.layer );
// Always re-index because of possible different app structure
of multiple tests.
indexingModule.services(
ReindexingStrategy.ReindexingStrategyService.class ).withMixins(
ReindexingStrategy.AlwaysNeed.class ).identifiedBy( "reindexer" );
config.entities( ReindexerConfiguration.class ).visibleIn(
Visibility.layer );
// 2.) In-memory Entity Store
ModuleAssembly entityStoreModule = infrastructureLayer.module(
"INFRASTRUCTURE-EntityStore" );
entityStoreModule
.services(
MemoryEntityStoreService.class,
UuidIdentityGeneratorService.class )
.instantiateOnStartup()
.visibleIn( application );
}
I try already many combinations - without success. Would be great if one of
you guys
can give me an idea what is wrong with my code.
Thanks,
Cheers,
Jiri
