<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      <exclusions>
        <!--去除内嵌tomcat -->

          <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
    <!--添加servlet的依赖-->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>

spring:
  main:
   web-application-type: none

@SpringBootApplication
public class TestiopojApplication extends SpringBootServletInitializer {

  public static void main(String[] args) {
    System.out.println("项目开始启动，开始执行任务============");
    SpringApplication.run(TestiopojApplication.class, args);
    String file = "E:\\copyFile";//文件存放路径
    String fileName = "test测试";//生成的文件名
    String strContext = "测试成功=======";//文件内容
    try {
      FileUtils.writeStringToFile((new File(file + File.separator + fileName + ".txt")), strContext, "UTF-8");
      System.out.println("文件创建成功============");
    } catch (IOException e) {
      System.out.println("文件创建失败============");
    }
  }
