SpringBoot03 项目热部署

1 问题

　　在编写springBoot项目时，经常需要修改代码；但是每次修改代码后都需重新启动，修改的代码才会生效

2 这么实现IDEA能够像Eclipse那样保存过后就可以自动进行刷新呢

　　将springBoot项目进行热部署即可

3 如何实现SpringBoot项目的热部署01

　　3.1 在插件中添加热部署所需的依赖

　　3.2 在设置中对compiler选项进行如下设置

　　3.3 设置registry

　　　　进入快捷键：ctrl + shift + alt + /

　　　3.4 修改完这些配置后重启IDEA再重新启动项目就实现了SpringBoot项目的热部署

4 如何实现springboot项目的热部署02

　　4.1 引入相关依赖包
