亲测有效

仅适用IDEA中，eclipse中不需要设置

一、开启idea自动make功能 

1 - Enable Automake from the compiler 

PRESS: CTRL + SHIFT + A 
TYPE: make project automatically 
PRESS: Enter 
Enable Make Project automatically feature 
2 - Enable Automake when the application is running 

PRESS: CTRL + SHIFT + A 
TYPE: Registry 
Find the key compiler.automake.allow.when.app.running and enable it 
Note: Restart your application now 

两步： 
1、CTRL + SHIFT + A --> 查找make project automatically --> 选中 
2、CTRL + SHIFT + A --> 查找Registry --> 找到并勾选compiler.automake.allow.when.app.running 

 

当然了，要在pom.xml中添加上 spring开发工具包

1 2 3 4 5 6

<dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-devtools</artifactId>             <optional>true</optional> <!-- 这个需要为 true 热部署才有效 -->             <scope>runtime</scope>  </dependency>

　　在IDEA中开启自动编译：
