Spring Boot作成非実行jarパッケージの実例教程

私たちはよくこのような場面があります。Spring Bootを普通のjarパッケージにするだけで、構成ファイルを含んでいません。他のアプリケーションに使うために。
本文はどのようにMavenを使ってSpring Bootアプリケーションを普通の非実行jarパッケージにするかを紹介します。
maven-jar-pluginの設定

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

      </configuration>

          <goals>
            <goal>jar</goal>
          </goals>
          <configuration>
            <!-- Need this to ensure application.yml is excluded -->
            <forceCreation>true</forceCreation>
            <excludes>
              <exclude>application.yml</exclude>
            </excludes>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

mvn clean packageパッケージを実行します。
