### 一、场景 ###

1、该项目在Linux和本机电脑上启动都正常

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.

    	at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.onRefresh(ServletWebServerApplicationContext.java:154)
    	... 8 common frames omitted

--------------------

### 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

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-tomcat</artifactId>
        
    	<scope>provided</scope>
    </dependency>

--------------------

### 四、解决 ###

调整后依赖导入配置

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

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
