Spring boot is a Java-based framework used for developing microservices. It is developed by the Spring team at Pivotal. Spring boot makes it easy to create stand-alone, production-grade Spring-based applications that can be “just run”. It takes an opinionated view of the Spring platform and Starters are a set of convenient dependency descriptors which can be included in your application.
Spring Boot is a Java-based framework that aims to simplify the process of creating microservices. It is built on top of the existing Spring framework and introduces a new approach to developing cloud-native applications.
The main benefits of using Spring Boot are:
1. It reduces the amount of boilerplate code required to set up a new microservice.
2. It includes a wide range of opinionated dependencies that can be configured out-of-the-box.
3. It provides sensible defaults for configuration options, making it easy to get started with a new service.
Within a Spring Boot application, there are a number of different types of components:
1. Web Components: These are the standard controllers, filters, and interceptors that make up a typical web application.
2. Data Access Components: These components deal with connecting to databases and performing CRUD operations.
3. Service Components: These components encapsulate the business logic of the application.
4. Security Components: These components handle authentication and authorization.
What are the key components of spring boot architecture?
Spring Boot is a java-based framework used for creating microservices. It is developed by Pivotal Team.
Spring Boot Starters: These are the dependencies that are need to be added in order to use Spring Boot features.
Spring Boot AutoConfigurator: This is used for auto-configuring the Spring Beans.
Spring Boot CLI: This is used for writing and running the Spring Boot applications.
Spring Boot Actuator: This is used for monitoring and managing the Spring Boot applications.
Microservices are a great way to break up a large application into smaller, more manageable pieces. They also allow for each service to be developed, tested, and deployed independently of the others, which can be a big advantage. However, microservices can also be more complex to manage and deploy, so it’s important to weigh the pros and cons before deciding if they’re right for your project.
Is Springboot a MVC
Spring Boot is a module of the Spring framework that provides a default configuration for packaging a Spring-based application. Spring MVC is a model view controller-based web framework under the Spring framework.
Spring Boot is a microservice-based framework that is built on top of the spring framework and is widely used to develop Rest APIs. The spring framework is a Java platform that provides comprehensive support for developing Java applications. Spring Boot consists of four layers: Presentation layer, Business layer, Persistence layer and Database layer.
What is JPA in spring boot?
JPA is a specification which specifies how to access, manage and persist information/data between java objects and relational databases. It provides a standard approach for ORM, Object Relational Mapping. Spring Boot provides a seemless integration with JPA.
Spring Boot is an application used to develop a stand-alone Microservice application and Spring Cloud is used to configure the communication between those services.
Both Spring Boot and Spring Cloud are needed to build a production-grade microservices system. Spring Boot provides the ability to package and run a microservice as a self-contained unit, while Spring Cloud provides the necessary tools and configurations for service discovery, load balancing, and circuit breaking.
Is REST API a microservice?
Microservices are a way to structure your application so that each individual service performs a specific task. This makes it easier to develop and maintain your application, as each service can be updated and redeployed independently.
REST APIs are the glue that binds these separate microservices together. They provide a way for different services to communicate with each other, allowing them to share data and functionality.
Developers can use microservices for a lot more than just building APIs. They can be used to build entire applications, or just parts of an application. Microservices can be deployed independently, making it easy to update and redeploy them without affecting the rest of the application.
Spring Boot is a great framework for creating microservices and production-ready standalone Spring MVC applications. It’s easy to use and makes development faster and easier.
Is Springboot front end or backend
Spring Boot is a great backend framework for Java developers. It is based on the Spring framework and allows developers to write production-grade backend web applications in Java. Spring Boot is very popular among developers because it makes backend development tasks easier and more efficient.
Spring Boot is a great framework for creating REST APIs. Some benefits of using Spring Boot include: no requirement for complex XML configurations, minimal configurations, and the ability to create REST APIs with ease.
Is Springboot using Log4j?
If you’re using Spring Boot, you can choose between Log4j or Log4j 2 for logging configuration. However, you can only use one of them if it’s on the classpath. If you’re using the starter poms for assembling dependencies, that means you have to exclude Logback and then include your chosen version of Log4j instead.
The four-tier architecture is a popular approach to organizing the components of a web application. The four layers are the presentation layer (PL), data service layer (DSL), business logic layer (BLL), and data access layer (DAL).
The presentation layer is responsible for handling the user interface, such as generating the HTML that is displayed in the browser. The DSL is responsible for fetching data from the database and providing it to the presentation layer. The BLL contains the business logic, such as validation and calculation, that is needed to process the data. The DAL is responsible for interacting with the database.
Each layer is responsible for a different area of the application, and they are typically organized into separate tiers, with each tier running on its own server. This separation of concerns can make the application more scalable and easier to maintain.
What are the 4 design principles of Spring
The OCP, LSP, ISP, and DIP are four important software design principles that every software engineer should know.
The OCP (Open-Closed Principle) states that a software module should be open for extension but closed for modification. That is, new functionality should be added by extending the software, not by modifying existing code.
The LSP (Liskov Substitution Principle) states that subclasses should be substitutable for their base class. That is, a client should be able to use a subclass without knowing it, and the subclass should not override any behavior of the base class that the client relies on.
The ISP (Interface Segregation Principle) states that a software module should not be forced to depend on functionality it does not use. That is, an interface should be split into smaller, more focused interfaces, each of which is only used by a subset of the module’s clients.
The DIP (Dependency Inversion Principle) states that a software module should not depend on another module’s implementation details. That is, modules should depend on abstractions, not concrete implementations.
Some best practices for Spring Boot projects are:
-Dividing the project into layers (service, entity, repository, etc.)
-Dividing the project into modules
-Using a consistent coding style
-Using a build tool such as Gradle or Maven
What does @data do in spring boot?
@Data is a shortcut annotation that combines the features of @ToString, @EqualsAndHashCode, @Getter / @Setter, and @RequiredArgsConstructor. In other words, @Data generates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields, setters for all non-final fields, and a toString() method that prints all fields. @Data also includes a @RequiredArgsConstructor, which generates a constructor that takes all final fields and annotated fields with @NonNull as arguments.
JPA is a standard provided by Java, while Hibernate is not. In hibernate, we use Session for handling the persistence of data, while in JPA we use Entity Manager. The query language in Hibernate is Hibernate Query language, while in JPA the query language is Java Persistence query language. Hibernate is one of the most JPA providers.
Conclusion
Spring Boot is a microservice-based framework that enables developers to quickly create production-ready applications. The framework is opinionated, meaning that it provides a set of guidelines for how applications should be built. This makes it easier for developers to get started with Spring Boot, as they do not need to configure every aspect of their applications. Spring Boot also includes a number of features that make it easier to develop and deploy applications, such as an embedded web server and auto-configuration.
Spring Boot is a great way to get started with developing Spring-based applications. It provides a simple and effective way to create stand-alone, production-grade Spring-based applications that can be easily deployed and started.
