1.2 BUILD ANYTHING

• Spring Boot is designed to get you up and running as quickly as possible, with minimal upfront configuration of Spring.
• Spring Boot takes an opinionated view of building production-ready
  applications.

[譯]

• Spring Boot爲快速啓動和運行以及最小化配置的Spring應用而設計。
• Spring Boot採用一套固化的認知來創建生產環境準備的應用。

1.3 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 very little Spring configuration.

[譯]

Spring Boot讓建立單獨的生產級別的Spring應用變得容易，你僅僅只須要運行便可。

咱們採用一套關於固化Spring平臺和第三包依賴庫的認知，以致於你能夠經過最小的煩惱來啓動。

大多數Spring Boot的應用程序只須要很是少的Spring配置。

1.4 Features

• Create stand-alone Spring applications
• Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR
  fifiles)
• Provide opinionated 'starter' dependencies to simplify your build
  confifiguration
• Automatically confifigure Spring and 3rd party libraries whenever
  possible
• Provide production-ready features such as metrics, health checks and
  externalized confifiguration
• Absolutely no code generation and no requirement for XML
  confifiguration

試想一下使用Spring或者Spring MVC的經歷，有哪些痛苦？

4 Spring Boot工程結構
4.1 Pom文件

4.2 XXXApplication

4.3 配置文件application.properties

4.4 templates和static

5 Spring Boot與微服務

5.1 再次理解Spring Boot

方便搭建和開發，總之很方便，後面再慢慢感覺。

5.2 微服務

Microservices連接：https://martinfowler.com/arti...

In short, the microservice architectural style [1] is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.
