Getting Started

Spring Boot helps you to create stand-alone, production-grade Spring-based applications that you
can run. We take an opinionated view of the Spring platform and third-party libraries, so that you
can get started with minimum fuss. Most Spring Boot applications need very little Spring
configuration.

spring-boot是spring的一个加强版，附带很多开箱即用的功能

Although there is nothing particularly special about Spring Boot (it is just
another library that you can consume), there are a few recommendations that, when followed,
make your development process a little easier.

Core Features

SpringApplication

FailureAnalyzer：没用到吧，写spring library的人会用到
java -jar myproject-0.0.1-SNAPSHOT.jar --debug

spring executable jar

Tasks expected to run during startup should be executed by CommandLineRunner and
ApplicationRunner components instead of using Spring component lifecycle callbacks
such as @PostConstruct.

If you need to access the application arguments that were passed to SpringApplication.run(…), you
can inject a org.springframework.boot.ApplicationArguments bean

一般都是通过环境变量获得。在backfill的情况下也是通过命令行获得。

If several CommandLineRunner or ApplicationRunner beans are defined that must be called in a specific
order, you can additionally implement the org.springframework.core.Ordered interface or use the
org.springframework.core.annotation.Order annotation.

Each SpringApplication registers a shutdown hook with the JVM to ensure that the
ApplicationContext closes gracefully on exit. All the standard Spring lifecycle callbacks (such as the
DisposableBean interface or the @PreDestroy annotation) can be used.

自动就有了啊
