Spring Boot簡介

1.什麼是spring bootjava

  簡單的說,spring boot就是整合了不少優秀的框架,不用咱們本身手動的去寫一堆xml配置而後進行配置。

  從本質上來講,Spring Boot就是Spring,它作了那些沒有它你也會去作的Spring Bean配置。它使用「習慣優於配置」(項目中存在大量的配置,此外還內置了一個習慣性的配置,讓你無需手動進行配置)的理念讓你的項目快速運行起來。使 用Spring Boot很容易建立一個獨立運行(運行jar,內嵌Servlet容器)、準生產級別的基於Spring框架的項目,使用Spring Boot你能夠不用或者只須要不多的Spring配置。redis

Spring Boot精要

Spring將不少魔法帶入了Spring應用程序的開發之中,其中最重要的是如下四個核心。spring

  • 自動配置:針對不少Spring應用程序常見的應用功能,Spring Boot能自動提供相關配置
  • 起步依賴:告訴Spring Boot須要什麼功能,它就能引入須要的庫。
  • 命令行界面:這是Spring Boot的可選特性,藉此你只需寫代碼就能完成完整的應用程序,無需傳統項目構建。
  • Actuator:讓你可以深刻運行中的Spring Boot應用程序,一探究竟。

  動態語言:不須要編譯,直接運行,好比JS。mongodb

  靜態語言:先編譯再運行。springboot

  配置指的是xml配置,低下的開發效率指的是編寫完代碼以後須要進行大量的xml配置,可是單從寫代碼而言,Java開發效率仍是比較高的,由於有許多寫好的第三方jar包。服務器

 

  微服務:將子系統拆成一個一個的jar包運行就是微服務。websocket

1 . springboot簡單介紹(http://projects.spring.io/spring-boot/)

        如今的web項目幾乎都會用到spring框架,而要使用spring不免須要配置大量的xml配置文件,而 springboot的出現解   決了這一問題,一個項目甚至不用部署到服務器上直接開跑,真像springboot所說:「just run」。

        springboot的不少默認編碼方式都是utf-8,真是福利啊

    org.spring 2013年新開發的框架springboot , 它讓一個單獨項目的建立變得更加的簡單,讓全部依賴spring的程序能夠作到「just run」。springboot提供大量第三方libraries讓咱們能夠很是輕鬆的開始建立一個spring工程,甚至不須要再去配置一些繁瑣的 xml配置文件

    框架特色:

    1:建立獨立的spring應用。

    2:嵌入Tomcat, Jetty Undertow 並且不須要部署他們。

    3:提供的「starters」poms來簡化Maven配置

    4:儘量自動配置spring應用。

    5:提供生產指標,健壯檢查和外部化配置

    6:絕對沒有代碼生成和XML配置要求

 

2.SpringBoot運行環境

Spring Boot最新版能夠運行在Java6+的環境下,可是Spring官方建議使用Java8。

Servlet 容器

Name Servlet Version Java Version
Tomcat 8 3.1 Java 7+
Tomcat 7 3.0 Java 6+
Jetty 9 3.1 Java 7+
Jetty 8 3.0 Java 6+
Undertow 1.1 3.1 Java 7+
