Spring Boot: exécution d'un projet multi-module
J'ai une application SpringBoot de base. En utilisant Spring Initializer, Tomcat intégré, le moteur de modèle Thymeleaf et le package en tant que fichier JAR exécutable . est un projet multi-module avec Spring Boot, le projet comportera 3 modules .

à partir de la racine parent, je génère tous les modules en utilisant:
mvn clean package
Mais le problème est que le tdk-web-0.0.2-SNAPSHOT.jar ne contient pas le tdk-core-0.0.2-SNAPSHOT.jar et qu’il échoue au démarrage.
Voici le résultat maven:

MacBook-Pro-de-nunito:tdk-cloud calzada$
C'est l'erreur que j'ai eu:
***************************
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.
J'ai décompressé le pot et il n'y a pas de classe du module de base
ajout du code proposé au module web:

J'ai l'erreur suivante: Error resolving template "/tdk/login/login", template might not exist or might not be accessible by any of the configured Template Reso
mais le modèle est là: 
Récemment, j'ai essayé d'implémenter une de mes structures/projets en tant que projet multi-modules.
J'ai suivi le lien suivant sur le guide du printemps, en espérant que cela vous aidera et à aider les autres Lien officiel du projet multi-modules du printemps
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>

Je suggère cela pour créer un fichier Jar exécutable.
Je pense que votre annotation @ComponentScan est manquante, voire erronée. (par exemple: @ComponentScan ({"com.tdkcloud.web"}) ne trouvera pas de services dans le package com.tdkcloud.backend). Ou peut-être que l'annotation @Service est absente de votre EmailService.
Donc, pour résoudre ce problème, votre code doit ressembler à ceci:
App.Java (ou Webconfig.Java)
@Configuration
@EnableWebMvc
@ComponentScan({"com.tdkcloud"})
@SpringBootApplication
public class App {
...
}
EmailService.Java
public interface EmailService {
...
}
EmailServiceImpl.Java
@Service
public class EmailServiceImpl {
...
}
version manque dans le module principal. essayez d'ajouter le module de base suivant pom
<version>0.0.2-SNAPSHOT</version>
alors ça devient.
<groupId>com.tdkcloud.core</groupId>
<artifactId>tdk-core</artifactId>
<packaging>jar</packaging>
<version>0.0.2-SNAPSHOT</version>
Le démarrage de printemps nécessite un bean de typecom.tdkcloud.backend.service.EmailServiceet ne le trouve pas. vous avez une solution de remorquage:
1- première solution: Créez le bean dans votre application comme ceci:
@Bean
public EmailService EmailService() {
return new com.tdkcloud.backend.service.EmailServiceImpl();
}
2 - Deuxième solution: Utilisez @ComponentScan comme ceci:
@ComponentScan(basePackages = {"com.tdkcloud.backend.service.EmailService"})
@SpringBootApplication
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
REMARQUE: vous devez avoir une annotation printanière dans votre package com.tdkcloud.backend.service.EmailService.
Essayez d'ajouter ceci.
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>exec</classifier>
</configuration>
</execution>
</executions>
</plugin>
Reconditionne les archives JAR et WAR existantes afin qu'elles puissent être exécutées à partir de la ligne de commande à l'aide de Java -jar. Avec layout = NONE, vous pouvez également utiliser simplement un package JAR avec des dépendances imbriquées (et aucune classe principale, donc non exécutable).
Obtenu de ce
Je faisais face au même problème plus tôt. Je suppose que vous n'exécutez pas le pot sous sa forme éclatée. Vous aurez probablement besoin de ce plugin pour insérer les pots dans le paquet et exécuter le fichier .original.
<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>
Cela regrouperait toutes les dépendances que vous avez définies dans votre pom à l'intérieur du pot. J'espère que cela t'aides.
