Spring Boot war package instance tutorial, springwar

In addition to executable jar packages, Spring Boot also supports traditional war packages. This article describes how to use Spring Boot to build a traditional war package.

Follow these steps to create a war package for Spring Boot:

1. Define the packaging type in pom. xml

<packaging>war</packaging>

2. Add the Spring Boot starter (you can also use 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. Add spring-boot-starter-web dependency

    <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. Add packaging plug-ins

  <build> <plugins>  <plugin>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-maven-plugin</artifactId>  </plugin> </plugins> </build>

5. The main class inherits SpringBootServletInitializer

/** * WAR application */@SpringBootApplicationpublic class WarApplication extends SpringBootServletInitializer {  public static void main(String[] args) { SpringApplication.run(WarApplication.class, args); }}

6. Run mvn clean package to package

$mvn clean package

7. Copy the prepared war package to a container (such as tomcat) and run it.

Here we need to briefly describe:

The main application can rewrite SpringBootServletInitializer with the configure method to customize Spring Boot configuration.

  /** * 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; }
