①将maven打包方式改为war

<packaging>war</packaging>

②在pom文件中引入依赖

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

③在启动类的同级目录下新建一个类

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(启动类.class);
    }
}

然后就可以maven install了，将war包放到tomcat下，启动就可以访问了。端口就是tomcat的端口，访问地址默认要带有你的war包名称
