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 */@SpringBootApplicationpublic 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; }
