摘要：springboot项目开发完成以后需要打包部署，打包方式支持jar包和war包，这篇文章讲述打包成war包。

1、pom文件修改

1.1 打包方式改成war

1.2 内置的tomcat依赖范围设置为provided，意为：项目在启动运行的时候不需要这个依赖。

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

1.3 springboot mven打包插件，可以仅设置finalName，不需要添加plugins插件（jar包时必须要添加）

<build>
            
            <finalName>springboot-demo</finalName>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

2、启动类修改，继承SpringBootServletInitializer接口，重写configure方法

@SpringBootApplication
    @MapperScan(basePackages = {"com.honor.mapper"})
    @EnableScheduling
    @ImportAutoConfiguration
    public class SpringbootDemoApplication extends SpringBootServletInitializer {
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(SpringbootDemoApplication.class);
        }
    
        public static void main(String[] args) {
            SpringApplication.run(SpringbootDemoApplication.class);
        }
    }

3、打包完成以后默认在target中，放到tomcat的webapps下启动就可以了

如果你的项目启动正常，但是访问接口路径显示404，请查看这篇帖子
