spring boot Error:(9, 8) java: 无法访问org.springframework.web.WebApplicationInitializer

Question

​
我初学spring boot，项目完成要发布到另一台tomcat服务器上，我按网上的做法，修改了application类，并在pom.xml中增加了dependency：

package com.salesdataforcreditprocess.sdcp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SdcpApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SdcpApplication.class);
    }
    public static void main(String[] args) throws Exception {
        SpringApplication.run(SdcpApplication.class, args);
    }


}

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.2.6.RELEASE</version>
</dependency>

**
**但是在idea环境中run，仍然报错如下：

Error:(9, 8) java: 无法访问org.springframework.web.WebApplicationInitializer
  找不到org.springframework.web.WebApplicationInitializer的类文件

请问怎么办？**

项目中是否有其他依赖，导致依赖之间存在冲突。
