Today, when I was teaching students at Jida University, I found that the way of configuring hot deployment in the Spring Boot project has changed a little bit. See below for details.
IDEA was recently updated to IntelliJ IDEA 2023.1 version
The first step is to add dependencies in the pom.xml file
<!--热部署配置 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<!-- 表示依赖不向下传递 -->
<optional>true</optional>
</dependency>

If you are using a Windows system, please follow the path of file -> settings -> Build, Execution, Deployment -> compiler to find build project automatically and check it, and finally Apply and OK;
If you are using a Mac system, please follow the path of IntelliJ IDEA -> settings -> Build, Execution, Deployment -> compiler to find the build project automatically and check it, and finally Apply and OK.

If you are using a Windows system, please follow the path of file -> settings -> Advanced Settings to find Allow auto-make to start even if developed application is currently running and check it, and finally Apply and OK;
If you are using a Mac system, please follow the path of IntelliJ IDEA -> settings -> Advanced Settings to find Allow auto-make to start even if developed application is currently running and check it, and finally Apply and OK;
