在某种情况下，比如。。。。。。。。。。之下，我们不得不，将springboot打成war包

1、在pom.xml文件中修改

<packaging>war</packaging>2、移除springboot自带的tomcat

<!--移除自带的tomcat-->

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-tomcat</artifactId>    <scope>provided</scope></dependency>3、在启动类上继承SpringBootServletInitializer

添加以下内容

@SpringBootApplication@EnableTransactionManagement  //开启事务public class WeiPaoApplication extends SpringBootServletInitializer{    public static void main(String[] args) {        SpringApplication.run( WeiPaoApplication.class, args );        System.out.println("我是大帅比");    }    /*将springboot项目打包成war*/    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(WeiPaoApplication.class);    }}4、全部处理完后，执行maven命令,跳过测试用例成功，到target文件中。包后缀为 war　　mvn clean install -Dmaven.test.skip=true
