1、修改pom.xml
父工程的pom.xml中的 <packaging>pom</packaging> spring boot项目应用中pom.xml中的 <packaging>war<packaging> <!--在父工程的pom.xml里,去除springboot web自带的tomcat,自己添加tomcat、servlet-api 依赖--> <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> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <scope>provided</scope> </dependency>
2.在有启动类的项目中,让启动类继承 SpringBootServletInitializer,重写 configure 方法。
@SpringBootApplication public class DemoApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(DemoApplication .class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { // 注意这里要指向原先用main方法执行的Application启动类 return builder.sources(DemoApplication .class); } }
