記錄一個Springboot啟動的問題->sprinboot正常啟動但是tomcat卻沒有啟動

• 啟動類如下

  @RestController
  @SpringBootApplication
  public class DemoDeployApplication {
  
      public static void main(String[] args) {
          SpringApplication.run(DemoDeployApplication.class, args);
      }
  
      @RequestMapping("hello")
      public String hello() {
          return "hello";
      }
  
  }
  

• 啟動日志如下

  2020-03-24 14:36:52.906  INFO 96874 --- [           main] demo.DemoDeployApplication               : Starting DemoDeployApplication on yangdeMacBook with PID 96874 (/Users/yang/IdeaProjects/demo/demo-deploy/target/classes started by yang in /Users/yang/IdeaProjects/demo)

  Process finished with exit code 0
  

• 從日志啟動日志看來，springboot內置的tomcat並沒有被啟動，端口也沒有監聽。

• 經過排查，終於找到了。。。

  pom依賴中,我的依賴是這樣的：

  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.2.4.RELEASE</version>
  </dependency>
  

  看了別的可以啟動的項目，改成了springboot的web依賴，終於好了。。。

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