## 1. 添加依赖开启热部署 ##

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                
                <optional>true</optional>
                <scope>true</scope>
            </dependency>

## 2. 配置插件，让依赖生效 ##

<plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        
                        <fork>true</fork>
                        <addResources>true</addResources>
                    </configuration>
                </plugin>

## 3. 设置开启自动构建项目 ##

File -> Settings -> 搜索Compiler -> 开启`Build Project automatically`

## 4. 改变注册表，开启`Compiler.autoMake.allow.when.app.running` ##

双击Shift，输入`registry`搜索找到Action的Registry，然后开启`Compiler.autoMake.allow.when.app.running`
