Spring Boot除了可以打可执行jar包外，也支持传统的war包。本文介绍如何使用Spring Boot构建传统war包。
Spring Boot打war包步骤如下：
1、在pom.xml里定义打包类型
<packaging>war</packaging>
2、添加Spring Boot启动器（也可通过parent）
<dependencyManagement> <dependencies> <dependency> <!-- Import dependency management from Spring Boot --> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>1.5.6.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
3、添加spring-boot-starter-web依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
4、添加打包插件
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>
5、主类继承SpringBootServletInitializer
/**
* WAR application
*/
@SpringBootApplication
public class WarApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(WarApplication.class, args);
}
}
6、执行mvn clean package打包
$mvn clean package
7、将打好的war包拷贝到容器（如tomcat）运行即可。
这里需要简单说明下：
主应用可以重写SpringBootServletInitializer里面有configure方法，自定义配置Spring Boot。
/**
* Configure the application. Normally all you would need to do is to add sources
* (e.g. config classes) because other settings have sensible defaults. You might
* choose (for instance) to add default command line arguments, or set an active
* Spring profile.
* @param builder a builder for the application context
* @return the application builder
* @see SpringApplicationBuilder
*/
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder;
}
