Spring Boot is a popular Java development framework designed to simplify and accelerate the development and deployment of Spring applications. As part of the Spring ecosystem, Spring Boot reduces tedious manual configuration by providing reasonable default configuration and out-of-the-box functionality, allowing developers to focus more on the implementation of business logic.
One of the main features of Spring Boot is Auto-configuration, which reduces the developer's workload by intelligently auto-configuring the application according to the project's dependencies and environment. Through automatic configuration, Spring Boot can automatically assemble Spring and third-party libraries according to the functions required by the application, which greatly simplifies the development process.
✨Characteristics
It is very important to understand the key features of Spring Boot, which lay the foundation for building stable and efficient distributed applications:
-
Embedded container : Spring Boot integrates a variety of embedded containers, such as Tomcat, Jetty, and Undertow, and can package applications into independent executable JAR files without additional installation and configuration of external servers.
-
Starter dependencies : Spring Boot provides a set of dependency management tools called starter dependencies. Developers can quickly integrate common functions and libraries such as database access, message queuing, and security as needed.
-
Auto-configuration : Spring Boot's auto-configuration mechanism automatically configures Spring applications based on the dependencies present in the classpath. It reduces the need for explicit configuration while remaining sufficiently flexible.
-
Actuator : Spring Boot Actuator is an extension library for monitoring and managing applications. It provides a wealth of endpoints for collecting application health status, logs, performance indicators and other information, which is convenient for developers to monitor and debug.
-
Configuration management : Spring Boot takes a simplified and flexible way to manage configuration. Developers can use property files, YAML files, environment variables, etc. to configure applications, and can easily switch between different environments.
-
Spring Data : Spring Boot integrates with Spring Data, simplifying access to various data stores. It provides a unified programming model that simplifies the development of functions such as database operations, cache access, and search.
-
Microservice support : Spring Boot is tightly integrated with Spring Cloud, making it easier to build and deploy distributed systems. Spring Cloud provides many functions, such as service registration and discovery, load balancing, circuit breakers, etc., to help developers build a reliable and elastic microservice architecture.
✨Relationship with spring
It is very important for Spring Boot to create Spring applications. That is, applications created using the Spring framework. The Spring here refers to the Spring Framework. The Spring we often say generally refers to the Spring family, including Spring Boot, Spring Framework, Spring Data, Spring Security, Spring Batch, Spring Shell, Spring for Apache Kafka....
In March 2004, Spring Framework 1.0 was released. In October 2006, Spring Framework 2.0 was released. After 2006, domestic projects gradually began to apply the Spring framework. In December 2009, Spring 3.0 was released. At this time, China has paid more attention to the use of Spring. Most of the projects have been transferred to the Spring framework. At that time, Struts or jsp+servlet+jdbc were used more. At that time, there was no trouble in R&D projects, and only one or two technologies could be used. There is nothing to choose. The current framework has too many technologies. In September 2017, Spring Framework 5.0 was released. In November 2022, Spring Framework 6.0 will be released.
Spring's core functions: IoC, AOP, transaction management, JDBC, Spring MVC, Spring WebFlux, integrated third-party framework MyBatis, Hibernate, Kafka, message queue... Spring includes Spring MVC, which is a powerful framework for web development. A module in .
First of all, it is clear that both Spring Boot and Spring Framework are created Spring applications. Spring Boot is a new framework that can be seen as an extension of the Spring framework. It eliminates the XML configuration required to set up Spring applications and provides a basic platform for creating Spring applications faster and more efficiently. Spring Boot can quickly create common applications and Web projects based on Spring and Spring MVC.
Spring Boot is an advanced framework including Spring and Spring MVC, which provides automatic functions, concise and efficient. Can create Spring applications faster. It eliminates Spring's XML configuration files, improves development efficiency, and reduces redundant code for Spring applications. Avoid a lot of boilerplate code.
So the suggestion for learning Spring Boot is: understand the core functions of Spring + Spring MVC, master the basic application is the best, and be able to get started with Spring Boot faster.
✨Spring Cloud Relationship
Spring Boot and Spring Cloud are two interrelated frameworks that solve different problems and can be used together.
Spring Boot is a framework for building self-contained, Spring-based applications. It simplifies the development process of Spring applications, providing features such as automatic configuration, quick startup, and embeddable Web servers. By providing out-of-the-box functions, Spring Boot enables developers to quickly build Spring-based applications without cumbersome configuration and adjustments.
Spring Cloud is a collection of tools for building distributed systems. It provides a series of functions and components for developing and managing microservices in distributed systems. Spring Cloud includes functions such as service registration and discovery, load balancing, circuit breaker, distributed configuration, message bus, etc. It is built on Spring Boot and simplifies the development and deployment process.
It can be said that Spring Cloud is built on the basis of Spring Boot, which extends the functions of Spring Boot and provides additional components and tools for building distributed systems. By using Spring Boot and Spring Cloud together, developers can build, deploy and manage complex distributed systems more easily, resulting in higher development efficiency and better scalability.
✨Summary
Spring Boot is a powerful framework that provides developers with a way to quickly build stable and efficient distributed applications. Spring Boot also provides rich development tools and ecosystem support. By using Spring Boot Actuator, developers can monitor and manage the running status of the application, and discover and solve potential problems in time. At the same time, Spring Boot's community and plug-in ecosystem are very active, from which developers can obtain many ready-made solutions and extended functions to speed up the development process.
And Spring Boot's microservice support makes building distributed systems easier and more reliable. Spring Cloud provides a set of mature microservice components, such as service registration and discovery, configuration center, circuit breaker, etc., which can help developers solve common problems in distributed systems and improve system scalability and elasticity.
