1.问题
报错如下：
Description:
Web application could not be started as there was no org.springframework.boot.web.servlet.server.ServletWebServerFactory bean defined in the context.
Action:
Check your application's dependencies for a supported servlet web server.
Check the configured web application type.
2.解决
启动项中写错了，应调用的是SpringBootCreateManualApplication的类而不是SpringApplication的类（SpringApplication是我写的前一个springboot项目启动项）
