第一步：声名打成WAR

<packaging>war</packaging>

第二步：排除SpringBoot自带的tomcat

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
</dependency>

第三步：引入Servlet依赖

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
</dependency>

第四步：插件

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
</plugin>

第五步：修改启动类

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 RunWarApplication extends SpringBootServletInitializer {
 
    public static void main(String[] args) {
        SpringApplication.run(RunWarApplication.class, args);
    }
 
    @Override
    public SpringApplicationBuilder createSpringApplicationBuilder() {
        return new SpringApplicationBuilder(RunWarApplication.class);
    }
}

第六步：编译打包，在target文件夹找到".war"文件
