IDEA+SpringBoot实现热部署(代码修改后实时生效)(hot reload/live reload)

1. 修改pom.xml

• 在project->dependencies下添加spring-boot-devtools依赖
• 在project->build->plugins下添加spring-boot-maven-plugin插件
  具体样例如下:

<project >
    ...
    <dependencies>
        ...
        <!--添加热部署-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
            <scope>true</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <!--热部署配置-->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <!--fork:如果没有该项配置,整个devtools不会起作用-->
                    <fork>true</fork>
                </configuration>
            </plugin>
            ...
        </plugins>
    </build>

</project>

2. 在设置界面中Compiler下,勾选“Build project automatically”

3. 按下快捷键 (Windows: ctrl + shift + alt + / , Mac: command(⌘)+shift(⇧)+option(⌥)+/),选择Registry...,勾上 compiler autoMake allow when app running

4. 重启ide,运行springboot工程.后续修改内容后,就会自动更新了.
