• Uses Groovy/Kotlin DSL
• Faster and more flexible

2.5 Example (Maven Dependency)

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>5.0.0</version>
</dependency>

• Dependency Injection

5.4 Spring Boot

• Simplifies setup
• Quick application development

5.5 Example (Spring Boot Main Class)

@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}
