Spring Boot：マルチモジュールプロジェクトの実行
基本的なSpringBootアプリがあります。 Spring Initializer、組み込みTomcat、Thymeleafテンプレートエンジン、および実行可能JARファイルとしてのパッケージを使用します。 Spring Bootを使用したマルチモジュールプロジェクトで、プロジェクトには3つのモジュールがあります。ここで、親モジュールpom.xml

親ルートから、次を使用してすべてのモジュールを生成します。
mvn clean package
しかし、問題は、tdk-web-0.0.2-SNAPSHOT.jarにtdk-core-0.0.2-SNAPSHOT.jarが含まれていないため、起動時に失敗することです。
ここでMavenの結果：

これは私が得たエラーです：
***************************
APPLICATION FAILED TO START

Description:
Field emailService in com.tdkcloud.web.controllers.AppErrorController required a bean of type 'com.tdkcloud.backend.service.EmailService' that could not be found.
Action:
Consider defining a bean of type 'com.tdkcloud.backend.service.EmailService' in your configuration.

しかし、テンプレートはあります： 
最近、プロジェクト構造/レイアウトの1つをMavenマルチモジュールプロジェクトとして実装しようとしました。
私は次の春のガイドリンクに従いましたが、これがあなたや他の人に役立つことを願っています 公式のSpringマルチモジュールプロジェクトリンク

実行可能Jarを作成するためにこれをお勧めします。
@ComponentScanアノテーションが欠落しているか、おそらく間違っていると思います。 （例：@ComponentScan（{"com.tdkcloud.web"}）はcom.tdkcloud.backendパッケージでサービスを見つけられません）。あるいは、@ ServiceアノテーションがEmailServiceにありません。
そのため、これを解決するには、コードを次のようにする必要があります。
App.Java（またはWebconfig.Java）
@Configuration
@EnableWebMvc
@ComponentScan({"com.tdkcloud"})
@SpringBootApplication
public class App {
...
}
EmailService.Java
public interface EmailService {
...
}
EmailServiceImpl.Java
@Service
public class EmailServiceImpl {
...
}
コアモジュールにversionがありません。次のコアモジュールpomを追加してみてください
<version>0.0.2-SNAPSHOT</version>
そうなります。
<groupId>com.tdkcloud.core</groupId>
<artifactId>tdk-core</artifactId>
<packaging>jar</packaging>
<version>0.0.2-SNAPSHOT</version>
Springブートには、タイプcom.tdkcloud.backend.service.EmailServiceのBeanが必要ですが、見つかりません。あなたは牽引ソリューションを持っています：
1-最初の解決策：アプリケーションで次のようにBeanを作成します。
@Bean
public EmailService EmailService() {
return new com.tdkcloud.backend.service.EmailServiceImpl();
}
2-2番目の解決策：@ ComponentScanを次のように使用します。
@ComponentScan(basePackages = {"com.tdkcloud.backend.service.EmailService"})
@SpringBootApplication
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
注：パッケージcom.tdkcloud.backend.service.EmailServiceにspring注釈が必要です。
これを追加してみてください。

既存のJARおよびWARアーカイブを再パッケージ化して、Java -jarを使用してコマンドラインから実行できるようにします。layout= NONEを使用すると、ネストされた依存関係を持つJARクラスなので、実行できません）。
this から取得
私は以前に同じ問題に直面していました。 jarを展開形式で実行していないと思います。おそらく、バンドル内のjarをプルして.original jarを実行するには、このプラグインが必要です。
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
これにより、jar内のpomで定義したすべての依存関係がバンドルされます。お役に立てれば。
