To wire up dependencies, we can use these two annotations provided by Spring—the @Required annotation and the @Autowired annotation. We can apply the @Required annotation to setter methods and the @Autowired annotation to constructor, methods, as well as fields.

- Constructor-based injection
- Setter-based/method-based injection
- Field-based injection.
