    一、场景

    1、该项目在Linux和本机电脑上启动都正常

    
    （图片来源网络，侵删）

    2、在另一台电脑上启动就报错

    3、代码都是同一份，没有差别

    二、报错信息

    org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

    三、原因

    导入spring-boot-starter-Tomcat依赖时定义的scope导致

    原依赖导入配置

    	org.springframework.boot
    	spring-boot-starter-tomcat
        
    	provided
    
    

    ---

    四、解决

    调整后依赖导入配置

    	org.springframework.boot
    	spring-boot-starter-tomcat
        
    	
    
    

    注：本机就算是provided也能正常启动，另一台电脑上就不行，应该是运行环境上的差异
