This demo shows basic use cases for some popular Dependency Injection frameworks. data-service project implements example service beans MessageService. There are two implementations of same MessageService interface.

1. itx.examples.di.service.impl.MessageServiceSyncImpl - synchronous service
2. itx.examples.di.service.impl.MessageServiceAsyncImpl - asynchronous service

data-service implementation requires only Java SE runtime and has no framework dependencies. MessageService is used in application examples for DI showcases.

app-simple - is plain Java SE application using MessageService without any DI framework.

Those projects are providers for various popular DI frameworks.

• di-spring - dependency injection for spring.io
• di-guice - dependency injection for google guice
• di-dagger - dependency injection for google dagger

• app-spring - example application using MessageService instances with spring DI system.
• app-guice - example application using MessageService instances with google guice DI system.
• app-dagger - example application using MessageService instances with google dagger DI system.
