1、去掉spring-boot-starter-web內建的Tomcat

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

2、修改打包型別

<packaging>war</packaging>

3、因為要在本地啟動，所有新增Tomcatjar包，將scope設定為provided，這樣在打war包的時候不會包含這個jar包

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

@SpringBootApplication
public class SpringbootApplication extends SpringBootServletInitializer {

按照從上到下點一遍，在target下找到war包，放到Tomcat的webapps下，啟動Tomcat，然後訪問localhost:埠號/war名稱/介面，如圖：
