SpringBoot实现热部署

① 在pom.xml中添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <version>2.1.3.RELEASE</version>
    //不传递依赖
    <optional>true</optional>
</dependency>

② 添加spring-boot-maven-plugin

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
            	//如果没有该项配置，devtools不会起作用，即应用不会restart
                <fork>true</fork>
            </configuration>
        </plugin>
    </plugins>
</build>

③ 修改application.properties文件

//热部署生效
spring.devtools.restart.enabled=true
//设置重启的目录
spring.devtools.restart.additional-paths=sr
//statics文件夹下内容修改不重启(文件夹必须存在)
spring.devtools.restart.exclude=statics/**

④ 修改idea配置

1. ctrl + shift + alt + / ===> Registry ===> 勾选compiler.automake.allow.when.app.running
   

2. File-Settings-Compiler-Build Project automatically
   

⑤ OK
