setup-base

Basic setup sample

Sample introduce base configuration concepts using bare minimum of guice-persist-orient configuration.

This sample requires only document api (the lowest api for orient), so will work with object and graph apis excluded:

implementation ('ru.vyarus:guice-persist-orient:4.0.0')
//implementation "com.orientechnologies:orientdb-object:3.0.38"
//implementation "com.orientechnologies:orientdb-graphdb:3.0.38"

DbModule class is application specific (configured guice-persist-orient for specific case) module. Like OrientModule it requires db constraints as parameters to be able to use it both in application and for tests (with in-memory db).

Custom scheme initializer ManualSchemeInitializer used to init database schema (one table Sample with two fields)

Custom data initializer SampleDataInitializer used to fill Sample table with some test data. This is useful for sample application or for testing purposes. Real application most likely, will not register custom data initializer.

In-memory

The first demo shows in-memory database initialization (such db exist only in memory and disappear after application shutdown): InMemoryDbApp

Demo use transactional service SampleService with basic orient api usage examples.

Local

The second demo shows local database initialization: LocalDbApp

Local database is stored on disk, so changes performed by demo stayed persisted. The limitation of local mode is single jvm usage (for example, you can't launch two application instances simultaneously). Local mode is faster than remote (because of no remote protocol overhead) and its ideal for embedded db mode.

Sample also demonstrates manual transaction definition.

Test

Sample spock tests prepared to show test setup using in-memory database.

AbstractTest do all test context setup, so actual tests could be simple: SampleServiceTest
