SpringBoot项目打成War包部署的方法步骤

<packaging>war</packaging>

<build>
    # 或者直接改成需要的名称
    <finalName>${artifactId}</finalName>
</build>

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-tomcat</artifactId>
			<!-- scope 各配置简单介绍
                1.test范围是指测试范围有效,在编译和打包时都不会使用这个依赖
                2.compile范围是指编译范围内有效,在编译和打包时都会将依赖存储进去
                3.provided依赖,在编译和测试过程中有效,最后生成的war包时不会加入 例如:
                    servlet-api,因为servlet-api在tomcat服务器已经存在了,如果再打包会冲突
                4.runtime在运行时候依赖,在编译时候不依赖
                5.system表示此依赖来自于外部jar, 而不是maven仓库
                如果引入依赖未指定，默认依赖范围是compile
            -->
   <scope>provided</scope>
</dependency>

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(DuanlinApplication.class, args);
    }
}

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication .class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(DemoApplication.class);
    }
}
