这算是启动成功了？为什么本地访问http://localhost:8080/依然访问不到呢？

Answer 1

starter 选错了，把 pom.xml 里的 spring-boot-starter 改为 spring-boot-starter-web 就好

Answer 2

你需要加个这：

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

Answer 3

idea

maven 图形化

maven 命令行
