SpringBoot打可执行war包

1. 主程序类：

@SpringBootApplication

public class Application extends SpringBootServletInitializer {

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(Application.class);

    }

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }

}

2. pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>com.cf</groupId>

  <artifactId>packagea</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <!-- 打包方式 -->

  <packaging>war</packaging>

	<parent>

		<groupId>org.springframework.boot</groupId>

		<artifactId>spring-boot-starter-parent</artifactId>

		<version>2.1.9.RELEASE</version>

		<relativePath/> <!-- lookup parent from repository -->

	</parent>

	<dependencies>

		<dependency>

			<groupId>org.springframework.boot</groupId>

			<artifactId>spring-boot-starter-web</artifactId>

		</dependency>

		<!-- 嵌入式tomcat相关jar将被放入到WEB-INF\lib-provided下 -->

		<dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-tomcat</artifactId>

            <scope>provided</scope>

        </dependency>

	</dependencies>

	<build>

		<plugins>

            <!-- 打包插件 -->

			<plugin>

				<groupId>org.springframework.boot</groupId>

				<artifactId>spring-boot-maven-plugin</artifactId>

			</plugin>

		</plugins>

	</build>

</project>

3. 使用maven打包(clean package)，此war包可以用于传统的部署方式（外部tomcat），也可以直接使用java -jar 的方式运行。
