启动spring boot项目时报错：java.lang.ClassNotFoundException: javax.servlet.Filter

修改前的配置

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!-- 打包war [2] 移除自带内置tomcat -->
            <exclusions>
                <exclusion>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                    <groupId>org.springframework.boot</groupId>
                </exclusion>
            </exclusions>
