将Spring Boot应用打包成可部署的War文件

1. 继承SpringBootServletInitializer类，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); } }

2. 修改pom.xml下的打包方式 

<packaging>war</packaging> 3. 去掉Spring Boot自带默认Tomcat容器

<dependencies> <!-- … --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <!-- … --> </dependencies> 4.  修改编译设置 

<build> <plugins> <plugin> <artifactId>maven-war-plugin</artifactId> <version>2.6</version> <configuration> <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。--> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </build>
