介绍：
上篇给大家介绍了ssm多模块项目的搭建，在搭建过程中spring整合springmvc和mybatis时会有很多的东西需要我们进行配置，这样不仅浪费了时间，也比较容易出错，由于这样问题的产生，pivotal团队提供了一款全新的框架，该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。通过这种方式，spring boot致力于在蓬勃发展的快速应用开发领域(rapid application development)成为领导者。
特点:
1. 创建独立的spring应用程序
2. 嵌入的tomcat，无需部署war文件
3. 简化maven配置
4. 自动配置spring
5. 提供生产就绪型功能，如指标，健康检查和外部配置
6. 绝对没有代码生成和对xml没有要求配置
(以上大部分内容摘自百度百科)
ok，关于springboot的讲解就到这里大家想了解的更详细可以自行百度。
搭建springboot项目我推荐大家用idea或者sts（spring tool suite spring公司自己研发的一款编辑器），我现在用的是idea，所以接下来我是用idea搭建项目的
一、创建项目
填写完group和atrifact后点击下一步，这里我选择的是jar，因为官方文档推荐的是打包成jar，所以这里就不过多解释了。
这里勾选上web
这里勾选上mysql、jdbc和mybatis点击下一步
这里输入项目名和项目路径后点击完成
这是新建完成后的项目结构
二、添加pom.xml依赖
因为springboot不推荐使用jsp做页面，如果想要使用就必需的添加jsp的依赖

三、springboot整合springmvc
因为在创建项目的时候我们选择了mybatis和jdbc所以在这里也要把他们两也给配置进去
编辑application.properties

# 页面默认前缀目录spring.mvc.view.prefix=/web-inf/jsp/# 响应页面默认后缀spring.mvc.view.suffix=.jsp#开发配置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 |
如果大家习惯用application.yml那也可以用，但是用application.yml在第一次启动项目的时候一定要maven clean一下，不然会报错。

编辑完application.properties之后再src/mian下创建webapp目录，结构如下
新建indexcontroller

运行main函数
访问页面，成功
四、springboot整合mybatis
