Spring Boot Annotations Spring Boot has revolutionized Java application development with its simplicity and extensive use of annotations. These annotations streamline configuration, reduce boilerplate code, and enhance the overall readability of applications. 1. @SpringBootApplication: This powerhouse annotation combines three essential annotations into one—@Configuration, @EnableAutoConfiguration, and @ComponentScan. It serves as the entry point of a Spring Boot application, enabling auto-configuration and component scanning within the specified package and its sub-packages. 2. @RestController and @RequestMapping: @RestController combines @Controller and @ResponseBody, making it easier to create RESTful web services. It handles HTTP requests and directly returns the response body. @RequestMapping complements it by mapping HTTP requests to specific handler methods or classes, simplifying URL routing. 3. HTTP Method Specific Annotations: Annotations like @GetMapping, @PostMapping, @PutMapping, and @DeleteMapping provide shortcuts for handling HTTP methods. These annotations streamline the process of defining endpoints and handling specific types of requests, such as retrieving data, creating resources, updating data, and deleting resources. 4. @Autowired: This annotation facilitates automatic dependency injection, a cornerstone of Spring’s Inversion of Control (IoC) container. It simplifies the management of dependencies by automatically wiring beans into the application, promoting loose coupling and enhancing testability. 5. Stereotype Annotations: Annotations like @Component, @Service, @Repository, and @Controller aid in structuring Spring applications. They help in organizing and managing beans across different layers of the application—whether for generic components, service-layer beans, data access objects (DAOs), or presentation-layer components. Spring Boot annotations not only simplify the development process but also promote best practices in Java application architecture. By leveraging these annotations, developers can focus more on business logic and less on infrastructure concerns, making Spring Boot a preferred framework for modern Java applications. Mastering these annotations empowers developers to build robust, scalable, and maintainable Java applications efficiently. Whether you're new to Spring Boot or looking to deepen your understanding, harnessing the power of annotations is key to unlocking the framework's full potential.

Day 33 of Learning Full-stack JAVA Development Advanced JAVA Topics - #Spring frameworks Spring provides an easy and friendly environment to create Java enterprise applications. It is full of features and provides various other sub-projects such as Spring Security, Spring Boot, Spring MVC, Spring Cloud, Spring Data, etc that help to build applications accordingly.The core and heart of Spring is an IOC container that manages bean objects and allows dependency injection. #Features- Flexible Productive Fast Secure Supportive Everywhere #configuration Java-based configuration in Spring enables us to use plain Java classes (POJOs) and annotations to configure our application context. With Java-based configuration, we do not need XML files. Instead, we use Java code to define our beans and their relationships. There are two types of configuration mainly - 1.XML Configuration 2.java configuration #dependeny_injection Dependency Injection is the main functionality provided by Spring IOC(Inversion of Control). Dependency Injection in Spring also ensures loose coupling between the classes. There are two types of Spring Dependency Injection. -- 1.Setter Dependency Injection (SDI): 2.Constructor Dependency Injection (CDI): spring #IOC Spring IoC (Inversion of Control) Container is the core of Spring Framework. It creates the objects, configures and assembles their dependencies, manages their entire life cycle. The Container uses Dependency Injection(DI) to manage the components that make up the application. 2 types of IoC containers: 1.BeanFactory  2.ApplicationContext Spring #AOP Aspect oriented programming(AOP) as the name suggests uses aspects in programming. It can be defined as the breaking of code into different modules, also known as modularisation, where the aspect is the key unit of modularity. Spring #MVC A Spring MVC is a Java framework which is used to build web applications. It follows the Model-View-Controller design pattern. It implements all the basic features of a core spring framework like Inversion of Control, Dependency Injection. #Annotations Basically, there are 6 types of annotation available in the whole spring framework. Spring Core Annotations Spring Web Annotations Spring Boot Annotations Spring Scheduling Annotations Spring Data Annotations Spring Bean Annotations Spring #Bean Scope  The scope of a bean defines the life cycle and visibility of that bean in the contexts we use it. The latest version of the Spring framework defines 6 types of scopes: singleton prototype request session application websocket Spring Framework simplifies Java enterprise application development with features like dependency injection, IoC container, and modularity through AOP. It supports various configurations (XML and Java-based) and offers multiple modules like Spring Boot and Spring MVC. Key concepts include bean scopes (singleton, prototype, etc.), dependency injection types (setter, constructor), and annotations for configuration.
