spring boot（一）：什么是spring boot

什么是spring boot

官网说的很清晰

一、Overview

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run".

We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need minimal Spring configuration.

spring boot可以很轻松的创建独立的、基于spring的生产级应用，你需要做的仅仅是运行它。

spring boot提供了对spring平台和第三方包的支持，你可以很快的入手。大多数spring boot应用只需要很少的spring配置。

二、Features

• Create stand-alone Spring applications（创建独立的spring应用）

• Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)（集成tomcat、jetty、undertow等内置容器，无需打成war包）

• Provide opinionated 'starter' dependencies to simplify your build configuration（提供可选的starter来简化依赖配置）

• Automatically configure Spring and 3rd party libraries whenever possible（随时可以自动配置spring和第三方jar包）

• Provide production-ready features such as metrics, health checks, and externalized configuration（提供生成环境特性如指标信息、健康检查和外部化配置）

• Absolutely no code generation and no requirement for XML configuration（无需生成代码和xml配置）
