springboot部署tomcat

package方式设置成war

<packaging>war</packaging>

排除自带的tomcat

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

启动类继承SpringBootServletInitializer并重写configure方法

    @SpringBootApplication
    public class App extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    }
