Chapter 2. Configuring your application to use Spring Boot

Reference the Spring Boot BOM (Bill of Materials) artifact in the pom.xml file at the root directory of your application.

Prerequisites

  • A Maven-based application

Procedure

  1. Open the pom.xml file, add the me.snowdrop:spring-boot-bom artifact to the <dependencyManagement> section, and specify the <type>pom</type> and <scope>import</scope>: 

    <project>
  ...
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>me.snowdrop</groupId>
        <artifactId>spring-boot-bom</artifactId>
        <version>2.1.15.Final-redhat-00001</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>
  ...
</project>

  2. Include the following properties to track the version of Spring Boot and the Spring Boot Maven Plugin you are using: 

    <project>
  ...
  <properties>
    <spring-boot.version>2.1.15.RELEASE</spring-boot.version>
    <spring-boot-maven-plugin.version>2.1.15.RELEASE</spring-boot-maven-plugin.version>
  </properties>
  ...
</project>

  3. Specify the repositories containing Spring Boot Starters and the Spring Boot Maven Plugin: 

      <!-- Specify the repositories containing Spring Boot artifacts. -->
  <repositories>
    <repository>
      <id>redhat-ga</id>
      <name>Red Hat GA Repository</name>
      <url>https://maven.repository.redhat.com/ga/</url>
    </repository>
  </repositories>

  <!-- Specify the repositories containing the plugins used to execute the build of your application. -->
  <pluginRepositories>
    <pluginRepository>
      <id>redhat-ga</id>
      <name>Red Hat GA Repository</name>
      <url>https://maven.repository.redhat.com/ga/</url>
    </pluginRepository>
  </pluginRepositories>

  4. Reference spring-boot-maven-plugin as the plugin used to package your application: 

    <project>
  ...
  <build>
    <plugins>
        ...
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>${spring-boot-maven-plugin.version}</version>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
              </executions>
            <configuration>
                <redeploy>true</redeploy>
            </configuration>
        </plugin>
        ...
    </plugins>
  </build>
  ...
</project>
