介紹：
上篇給大家介紹了ssm多模塊項目的搭建，在搭建過程中spring整合springmvc和mybatis時會有很多的東西需要我們進行配置，這樣不僅浪費了時間，也比較容易出錯，由于這樣問題的產生，pivotal團隊提供了一款全新的框架，該框架使用了特定的方式來進行配置，從而使開發人員不再需要定義樣板化的配置。通過這種方式，spring boot致力于在蓬勃發展的快速應用開發領域(rapid application development)成為領導者。
特點:
1. 創建獨立的spring應用程序
2. 嵌入的tomcat，無需部署war文件
3. 簡化maven配置
4. 自動配置spring
5. 提供生產就緒型功能，如指標，健康檢查和外部配置
6. 絕對沒有代碼生成和對xml沒有要求配置
(以上大部分內容摘自百度百科)
ok，關于springboot的講解就到這里大家想了解的更詳細可以自行百度。
搭建springboot項目我推薦大家用idea或者sts（spring tool suite spring公司自己研發的一款編輯器），我現在用的是idea，所以接下來我是用idea搭建項目的
一、創建項目
填寫完group和atrifact后點擊下一步，這里我選擇的是jar，因為官方文檔推薦的是打包成jar，所以這里就不過多解釋了。
這里勾選上web
這里勾選上mysql、jdbc和mybatis點擊下一步
這里輸入項目名和項目路徑后點擊完成
這是新建完成后的項目結構
二、添加pom.xml依賴
因為springboot不推薦使用jsp做頁面，如果想要使用就必需的添加jsp的依賴

三、springboot整合springmvc
因為在創建項目的時候我們選擇了mybatis和jdbc所以在這里也要把他們兩也給配置進去
編輯application.properties

# 頁面默認前綴目錄spring.mvc.view.prefix=/web-inf/jsp/# 響應頁面默認后綴spring.mvc.view.suffix=.jsp#開發配置spring.datasource.driverclassname = com.mysql.jdbc.driverspring.datasource.url = jdbc:mysql://localhost:3306/test?useunicode=true&characterencoding=utf-8spring.datasource.username = rootspring.datasource.password = 123456# mybatis接口文件位置mybatis.mapper-locations: classpath:mapper/*.xmlmybatis.type-aliases-package: com.chaoqi.springboot_demo2.domain |
如果大家習慣用application.yml那也可以用，但是用application.yml在第一次啟動項目的時候一定要maven clean一下，不然會報錯。

編輯完application.properties之后再src/mian下創建webapp目錄，結構如下
新建indexcontroller

運行main函數
訪問頁面，成功
四、springboot整合mybatis
