1先去你要使用的工程添加依赖:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency>2然后去父工程下添加插件:
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <fork>true</fork> <addResources>true</addResources> </configuration> </plugin> </plugins> </build>3开启自动编译
按快捷键并且去寻找蓝色选项打勾,可以不开,回头手动Ctrl+f9
