Spring Boot series (1) Spring Boot introduction and basic POM file

Spring Bootis a new framework provided by the Pivotal team, designed to simplify Springthe initial setup and development of new applications. The framework uses a specific way to configure, so that developers no longer need to define boilerplate configuration. rapid application developmentIn this way, Boot aims to be a leader in the burgeoning field of rapid application development ( ).

 

Features of Spring Boot

1. Create a standalone Springapplication

2. Embed directly Tomcat, Jettyor Undertow, without deploying WARfiles

3. Provide recommended base POMfiles to simplify Apache Mavenconfiguration

Spring4. Automatically configure the framework based on project dependencies as much as possible

5. Provide production-ready features such as metrics, health checks, and external configuration

6. Absolutely no code generation and XMLno configuration required

 

Advantages of Spring Boot

spring bootIt can support developers to quickly develop a restfulstyle of microservice architecture;

spring bootAutomation is really convenient, and it is perfect for microservices. It is very convenient to deploy and manage a single jar package. As long as the system architecture is reasonably designed, large-scale projects can also be used, and with nginxload balancing, horizontal expansion can be easily achieved;

spring bootThe problem to be solved, thin configuration is on the one hand, and on the other hand, how to easily springintegrate the ecosystem with other tool chains (for example Redis, email, elasticsearch).

Spring BootMakes developing stand-alone, production-level Spring-based applications as simple as " just run". Provides out-of-the-box settings for the Springplatform and third-party libraries so you can get started in an orderly manner.
