Idea中Springboot热部署无效怎么解决

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

<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：
