(1)遵循"习惯优于配置"原则,使用Spirng Boot只需很少的配置,大部分时候可以使用默认配置; (2)项目快速搭建,另外还可以无配置整合第三方框架; (3)可完全不使用xml配置,只使用自动配置和Java Config; (4)内嵌入Servlet如Tomcat容器,应用可用jar包运行(java -jar); (5)运行中应用状态的监控.
因为我是用Idea基于Maven项目集合的Springboot框架，若不会用Idea创建Maven项目，那么请您点这里 https://blog.csdn.net/qq_42090683/article/details/83211430（使用idea创建Maven项目）
一：创建完Maven项目后，则需要在pom.xml中添加Springboot的依赖，然后让它自己把jar包下载完后，就可以下一步了

资源文件里面暂时写一个端口号就行
server.port=80`
三：写一个启动类来运行，这个启动类要使它能够扫描所有的包 例如： 下面贴出启动类的代码块
package com.liufu; import org.mybatis.spring.annotation.MapperScan; import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; import org.springframework.transaction.annotation.EnableTransactionManagement; /** * @Auther: ${liufu} * @Date: 2018/9/16 12:23 * @Description: */ @SpringBootApplication public class MybatisApplication { public static void main(String[] args) { SpringApplication.run(MybatisApplication.class,args); } } 下面直接run这个启动类就OK了 运行成功后如以下：
