Guice is a lightweight dependency injection framework for Java 11+, developed by Google. It eliminates the need for manual factories and 'new' calls by wiring dependencies via type-safe @Inject annotations.

Use cases

• inject dependencies into java classes without factories
• make java code easier to unit test with mockable dependencies
• wire up services in a large java application
• replace manual singleton and factory patterns with annotation-based DI
• manage javax vs jakarta injection annotations across java versions

When to choose

• you want a mature, battle-tested DI framework for Java with Google backing
• your project uses javax.inject or jakarta.inject annotations
• you prefer type-safe, annotation-driven wiring over XML configuration
• you need helpful error messages and extensibility in a DI container

When to avoid

• you are using Spring and want its full ecosystem (web, data, security) rather than just DI
• you need compile-time dependency injection like Dagger for Android or GraalVM native images
• your project targets Java versions below 11
• you want CDI-compliant enterprise dependency injection
