这不是报错……
有什么问题呢

看下你的pom文件springboot启动器是不是spring‐boot‐starter‐web

<!-- springboot启动器 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <!-- 如果是web项目 依赖改成spring‐boot‐starter‐web
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring‐boot‐starter‐web</artifactId>
        </dependency>
        -->

你没有配置文件的吗
