1. 不继承spring-boot-starter-parent

<dependency>
            <!-- Import dependency management from Spring Boot -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>

            <type>pom</type>
            <scope>import</scope>
        </dependency>

2. 热部署

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