springboot打包成war包

在配置文件中設置打包方式爲war

<packaging>war</packaging>

修改啓動類，繼承SpringBootServletInitializer類，並且重寫configure方法

public class XdclassApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(XdclassApplication.class);
    }

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

}

確保內置servlet container 不會干涉發佈該war包的servlet container，方案是標記內置servlet container 的依賴爲    provided，打好war  包 放在 tomcat下就可以了
