Answer 1

Je ne vois rien de vraiment flagrant avec ce que vous avez. J'ai une application que je déploie simultanément en tant que jarre et guerre dans différents environnements (ils ne diffèrent que par leur emballage); J'ai un ServletInitializer équivalent au vôtre et cela fonctionne sans problème avec une différence principale.

J'utilise une configuration d'exécution maven avec spring-boot:run comme valeur "Ligne de commande". Avec cela, je ne peux rien faire de plus que de changer le pom pour refléter le jarre ou la guerre, courir et partir. J'ai rencontré des problèmes lors du basculement et de l'utilisation d'une configuration qui appelle main dans la classe d'application. Par exemple, juste pour le plaisir, je viens de lancer une instance de l'application avec jar packaging et main. Ne serait même pas lancer. Ceci est juste après l'avoir emballé et lancé en utilisant la configuration Maven que j'ai mentionnée ci-dessus.

Je recommanderais de commencer par créer cette configuration d'exécution maven et voir quels sont les résultats. Voici comment procéder dans Intellij afin que vous n'ayez pas à utiliser l'interface de ligne de commande.

1. Choisissez "Editer les configurations ..." dans le menu déroulant à côté du bouton de lecture.
2. Appuyez sur le + vert dans le coin supérieur gauche.
3. Choisissez de créer une configuration Maven.
4. Nomme le.
5. Ajoutez spring-boot:run à l'entrée "Ligne de commande".
6. Si vous le souhaitez, définissez-le "Partager" d ou "Une seule instance uniquement".

Je ne suis pas un utilisateur d'Eclipse/sts mais je suis sûr qu'il existe une manière similaire de le faire.

Answer 2

Apparemment, vous allez empaqueter votre application en tant que war, c'est correct, mais le problème est que vous l'exécutez via la méthode main dans la classe InternetMovieDatabaseApplication. Au lieu de cela, vous devez déployer votre application sur un Standalone Servlet Container , comme Tomcat ou Jetty , ou exécuter l'application à l'aide de la commande mvn spring-boot:run.

Si empaqueter votre application sous la forme d'une archive war n'est pas une exigence stricte, je vous recommande de make jar, pas war . Pour ce faire, commencez par supprimer la packaging de votre pom.xml:

<packaging>war</packaging>

Puis supprimez la dépendance spring-boot-starter-Tomcat:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-Tomcat</artifactId>
    <scope>provided</scope>
</dependency>

Enfin, supprimez la classe ServletInitializer et exécutez la méthode main dans votre classe InternetMovieDatabaseApplication.

Answer 3

Je ne pense pas que vous ayez besoin de votre ServletInitializer

votre InternetMovieDatabaseApplication avec l'annotation @SpringBootApplication devrait suffire.
