IDEA 2022.3.3 修改代码后自动加载/热部署设置 ​

1. 在 pom.xml 里添加依赖 ​

添加开发者工具依赖 ​

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

添加 maven 插件 ​

xml
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <fork>true</fork>
                <addResources>true</addResources>
            </configuration>
        </plugin>
    </plugins>
</build>

2. 编译选项里勾选 Build project automatically ​

idea-hot-deploy

3. 高级设置里勾选 Allow auto-make to start even if developed application is currently running ​

idea-hot-deploy

4. 重启 idea, 启动项目，日志出现 restartedMain 表示成功 ​
