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
|
1
|
<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
|
1
|
$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;
}
