1、错误信息

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.

2、解决方案

        （1）检查在main方法所在的类是否添加@SpringBootApplication注解

        （2）检查在pom.xml是否添加依赖

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

        如果以上都没有错误，检查测试代码是否正确

@SpringBootApplication
public class SpringBootSelfApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootSelfApplication.class, args);
    }
}

        出现以下信息表示测试成功！
