spring boot 打war包部署，打jar包

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

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected 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
