篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了IDEA下的SpringBoot工程的如何打包成war包相关的知识，希望对你有一定的参考价值。

1.在pom文件下添加

<packaging>war</packaging>

2.在pom下移除tomcat插件

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- 移除嵌入式tomcat插件 -->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

3.添加server-api依赖，（此时运行会报错，把<scope>provided</scope>去掉才能运行）

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

4.修改启动类

@SpringBootApplication
public class GuangdongApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意这里要指向原先用main方法执行的Application启动类
        return builder.sources(GuangdongApplication.class);
    }
  public static void main(String[] args) {
        SpringApplication.run(GuangdongApplication.class, args);
    }

}

5.点击菜单栏的=Bulid-Bulid Project
