一、启动类忘记添加注解

二、缺少依赖，添加即可

三、启动类main方法写错

四、移除排除项

五、我的解决方案

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

报错信息如下：Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean

在Spring Boot项目中，出现这个错误有几种情况：

# 一、启动类忘记添加注解 #

在main方法所在的类忘记添加@SpringBootApplication；

# 二、缺少依赖，添加即可 #

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

# 三、启动类main方法写错 #

就是把SpringApplication.run(XxxApplication.class,args);写成了SpringApplication.run(SpringApplication.class,args);

应该是本项目的启动类名.class，如：**SpringApplication.run(启动类名.class,args);**

# 四、移除排除项 #

**我试了第四个解决方案移除排除项是可以完美解决我的问题。**

# 五、我的解决方案 #

在网上搜集了几种可能出现的问题原因，但是我的都不是这些问题，找了很久，终于找到了，是与pom.xml有关的，具体如下：

错误写法：

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

正确写法：**<scope>里的provided改为provide即可。**

至于为什么还没有查清楚，后续再更新！

完结！
