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
<!--热部署相关-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
4.2 插件配置
4.2 修改IDEA设置
4.3 修改全局设置
