1.打war包,先把pom文件packaging由jar改成war:

2.Application文件:

@SpringBootApplication
public class Application extends SpringBootServletInitializer
        implements EmbeddedServletContainerCustomizer {
    public static void main(String[] args) {
        ConfigurableApplicationContext run = SpringApplication.run(Application.class, args);
    }
    //集成SpringBootServletInitializer,configure实现打war包
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
    //下边customize方法实现EmbeddedServletContainerCustomizer 接口,实现了
    //更改tomcat端口号的需求
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        container.setPort(8080);
    }
}

3.pom文件的spring-boot-starter-web里添加代码,移除嵌入式tomcat插件
添加代码,这段就老生常谈了

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

4.添加servlet-api的依赖

题外

改变war包包名

pom文件build关键字里加上

包名
