官方文档：http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
一：更改程序入口类 Application.java 使其继承SpringBootServletInitializer，并重写configure方法
@SpringBootApplicationpublic class Application extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(Application.class);}public static void main(String[] args) throws Exception {SpringApplication.run(Application.class, args);}}
二：更改pom.xml
<packaging>war</packaging>
三：确保内置servlet container 不会干涉发布该war包的servlet container，方案是标记内置servlet container 的依赖为provided
<dependencies><!-- … --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency><!-- … --></dependencies>
最后，将打好的war包放到tomcat下即可
打成可以运行jar包
还原上面第一步的操作，在pom.xml中添加maven-plugin
<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>
运行：Java -jar myapp.jar
