Constructor-based dependency injection in Java Spring is a method of providing dependencies to a class through its constructor. This approach allows the Spring framework to manage and inject required dependencies when creating an instance of a class. ### Key Features: 1. **Immutable Dependencies**: Dependencies are provided at the time of object creation, promoting immutability. 2. **Explicit Dependencies**: The constructor clearly defines all required dependencies, making it easier to understand what a class needs to function. 3. **Spring Configuration**: You can configure dependencies using XML or Java annotations (e.g., `@Autowired`). ### Example: ```java @Component public class Service { private final Repository repository; @Autowired public Service(Repository repository) { this.repository = repository; } } ``` In this example, the `Service` class requires a `Repository` instance, which Spring provides through the constructor. This approach enhances clarity and testability in your code. read less
