Spring Boot打war包的实例教程

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;
}
