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
<!-- 导入Spirng Boot web 所需的jar包 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<exclusions>

<artifactId>spring-boot-starter-tomcat</artifactId>

<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>
