1.修改打包方式

<packaging>jar</packaging>改为<packaging>war</packaging>

2.排除spring-boot-starter-web所自带的tomcat依赖

<!-- 导入Spirng Boot  web 所需的jar包 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- 移除嵌入式tomcat插件 -->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

3.添加Servlet依赖，只在编译时有效

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

4.修改入口方法 继承一个SpringBootServletInitializer类，并且覆盖configure方法

5.配置打包后的 war 名称

打包命令：mvn clean package

<build>
    <plugins>
        <!-- 添加打包名称插件，每次打包后不需要再改名字了 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <!-- <warSourceExcludes>src/main/resources/**</warSourceExcludes>   -->
                <!-- warName 就是 mvn clean package 执行完的包 -->
                <warName>springBoot</warName>
            </configuration>
        </plugin>
    </plugins>
</build>
