Caused by: java.lang.ClassNotFoundException: javax.servlet.http.HttpServletRequest

1、看下POM.XML中有没有

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
    <scope>provided</scope>
</dependency>

2、POM.XML中不应有，会有版本冲突

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