## **idea配置springboot热部署终极解决办法，解决热部署失效问题** ##

## **1. 添加maven依赖** ##

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <version>2.2.5.RELEASE</version>
                <optional>true</optional>
            </dependency>

## **2. 添加插件** ##

<plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <version>2.2.5.RELEASE</version>
                    <configuration>
                        <fork>true</fork>
                        <addResources>true</addResources>
                    </configuration>
                </plugin>

## **3.开启自动编译** ##

*  Ctrl+Alt+S打开配置

## **5.设置项目启动加载方式** ##

*  **菜单栏选择 Run->Edit Configurations…**

    **找到spring boot下的 On ‘Update’ action 和 On frame deactivation** **，选择 Update classes and resources**

    **最后测试热部署，随便修改一个类中的代码，查看idea最下方的提示条，出现 build 后 紧接着 出现 parsing java… 表示正在重新编译，等待项目自动重新启动后就可以看见修改的类生效了**
