对于创建的jsp的web项目，有时想把项目打成war包部署到外部的Tomcat上，要达到这种目的，需要修改一些东西。

# 一、修改Maven的打包方式 #

Maven默认的`packing`为`jar`，所以要将其改为`war`:

# 二、修改内迁容器的依赖范围 #

将spring-boot-starter-tomcat的要构建可执行并可部署到外部容器中的war文件，需要将嵌入容器依赖项标记为“provided”，如以下示例所示：

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-tomcat</artifactId>
    	<scope>provided</scope>
    </dependency>

# 三、修改启动类 #

修改启动类，继承SpringBootServletInitializer并重写configure方法。如下：

@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);
    	}
    
    }
