需要添加插件

		<plugin>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-maven-plugin</artifactId>
          <version>1.5.9.RELEASE</version>
        </plugin>

packaging标签里为jar

  <groupId>com.lahhass</groupId>
  <artifactId>seckill_idea</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

执行命令

mvn clean package

或

mvn install

target目录下生成jar包，打开如图

META-INF下的MANIFEST.MF文件需要有如下信息

Manifest-Version: 1.0
Implementation-Title: seckill_idea
Implementation-Version: 1.0-SNAPSHOT
Built-By: Administrator
Implementation-Vendor-Id: com.lahhass
Spring-Boot-Version: 1.5.9.RELEASE
Implementation-Vendor: Pivotal Software, Inc.
Main-Class: org.springframework.boot.loader.JarLauncher
Start-Class: com.lahhass.seckill.MainApplication
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/
Created-By: Apache Maven 3.3.9
Build-Jdk: 1.8.0_51
Implementation-URL: http://www.example.com

可能发生的问题：没有BOOT-INF文件夹，MANIFEST.MF文件没有主清单属性
解决方法：将外层的pluginManagement标签去掉，mvn clean后再生成jar包
