SpringBoot+Mybatis

玩了一段時間了，上網轉了轉，發現網上有許多SpringBoot框架架構的相關教程，不過都比較簡短，可能小萌新看懂需要花費很多腦力和時間，所以本人就決定寫一篇所有人都能輕鬆看懂的教程，還望大家多多支持hhh~~~

如果你是以下兩種人的其中一種

熟練愛好者：那麼你如果忘記了有pom.xml和ymal文件、properties文件詳細配置，你可以在本篇中直接找乾貨COPY.(^o)/~
小萌新：那麼建議你能夠耐心堅持下去，祝你們學習愉快！

SpringBoot可以說是目前Java開發非常主流的框架了，可以很簡單的創造出許多漂亮網站的功能。

總的一句話概括SpringBoot就是：Boot！快速啓動！習慣優於配置！大道至簡！

怎麼理解這句話呢？其實就是說，相比於SSM定義很多複雜的Bean或者Config其他的配置。Springboot中，基本上它可以“讀懂”你的意思，幫你把看似機械化的架構和配置工作。全部做完、十分簡單、甚至Tomcat都不用。

然後Springboot真的可以很簡單~，只要好好學習自己手動架構一個也就理解了，架構完以後就能無限的Copy啦，其中簡單的說下Springboot的一些特點。

內置Tomcat
我覺得這個基本上顛覆了以前的傳統。怎麼理解？
你做完一個項目。直接打包成jar、然後找到一臺有JDK環境的地方，運行指令就可以直接啓動項目了~！
完全不需要去下載Tomcat、然後配置server.xml、然後放到webApp、然後用tomcat運行和啓動。同時還不會影響到其他項目的運行~！

前臺啓動：
	java -jar XXX.jar
後臺啓動：
	java -jar xxx.jar &
	
假設你打開Linux終端、如果用前臺運行的話、當你關閉終端時、也就停止了項目的運行。
所以、當你真正需要部署的時候，使用後臺部署模式。部署後你可以直接關閉終端。

默認配置
大道至簡。各種web支持。Mysql支持。Redis支持。都可以做到按照常用習慣自動配置
友好自定義配置
在resource目錄下創建名爲application.yaml的文件。可以在裏面對項目進行任何配置。

server:
  port: 8080
  servlet-path: /
spring:
    http:
      encoding:
        charset: utf-8
        enabled: true
        force: true
    resources:
          static-locations: classpath:/static/,classpath:/public/
    mvc:
      view:
        prefix: /WEB-INF/jsp/
        suffix: .jsp
    mail:
      host: smtp.163.com
      username: [email protected]
      password: xxxxx
      properties:
              mail:
                  smtp:
                      auth: true
                      timeout: 25000
mybatis:
  mapper-locations: cn.lantian.springboot.mapper.*.xml
  type-aliases-package: cn.lantian.springboot.model

#pagehelper分頁插件
pagehelper:
    helperDialect: mysql
    reasonable: true
    supportMethodsArguments: true
    params: count=countSql
logging:
  level: info

幾乎全註解模式
controller、service、配置、應有盡有
對其他開源系列都基本很友好
比如分頁插件、輕鬆一配、完成工作！

好、有一個小概念之後，我們正式來構建Springboot項目。因爲筆者使用的是IDEA作爲Java的IDE，那就以此爲例（編譯器大同小異，掌握了內部的來龍去脈用什麼都一樣）

創建一個maven項目

3.如果不出意外的話、你們的骨架就架構成功了。是不是層次看着特別舒服。

4.接下來我們導入Springboot框架中常用到的相關jar包。找到POM.XML文件

(^o)/~是這樣的。

O(∩_∩)O哈哈~然後看好了哦、放點東西進去

}

恭喜你、全部配置完成~!!!

最後、舒服一下吧。點擊main方法、直接啓動~
是不是突然覺得比SSM輕多了、快速啓動就是這個意思。

以上就是Springboot搭建的全過程啦~
還有什麼不明白疑問的地方、可以通過評論進行交流~

如果覺得不錯的小夥伴可以轉發哦讓更多同學看到、一起學習一起進步！！！
