彻底解决IDEA中SpringBoot热部署无效的问题

**开启SpringBoot热部署，首先得在pom.xml中引入依赖**

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

**但是你会发现，引入了依赖之后往往还是没用，改了代码还是得重启**

**问题原因：IDEA在默认情况下不会自动编译，需要更改一些配置**

**解决步骤：**

**1、开启IDEA静态的自动编译**

**按住Ctrl+ALT+S ，然后Build，Excution,Deployment -> Compiler ，确保勾选 Build project automatically**

**2、开启IDEA动态的自动编译**

**按住 Ctrl + Shift + Alt + / ，点击Registry**

**找到compiler.automake.allow.when.app.running，确保勾选上**

**找到compile.document.save.trigger.delay，和compile.automake.trigger.delay,数值设置的小一些**

**2、开启IDEA的热部署策略**

**3、关闭浏览器的缓存**

**这是最后一步，往往很多人败在这里，打开浏览器，按F12,选择NetWork，把Disable cache勾选上**

**此时，你就可以愉快地享受热部署带来的便利了。**
