bonjour à vous, je rencontre bien des problème lorsque je crée un projet spring cela me genere des erreurs, comme le montre cette image

je ne sais vraiment pas a quoi cela est du, pour tant j'applique la procédure de tuto à la lettre mais je n'obtiens toujours pas le même resultat

[tchize_]

Si tu nous donnais les messages d'erreurs, plutot qu'un screenshot coloré?

[cürüs]

salut, et merci pour l'intervention, j'ai executer le script avec spring boot et voici le message que la console m'a renvoyer

merci pour vos réactions

[tchize_]

je pensais plutôt à ces trois erreurs de compilation à l'écran, quels sont les messages?

[cürüs]

ok, salut une fois de plus,
La Ligne 1 renvois ce message d'erreur:
Multiple makers at this line
- The Type java.lang.string cannot be resolved. It is indirectly referenced from required .class file
- The Type java.lang.string cannot be resolved. It is indirectly referenced from required .class file
- The Type java.lang.string cannot be resolved. It is indirectly referenced from required .class file

La Ligne 7 renvois ce message d'erreur:
Implicit super constructor Object() is undefined for default constructor. Must define an explicit constructor

La Ligne 9 renvois ce message d'erreur:
String Cannot be resolved to a type.

c'est tout ce que je lis lorsque je pose le curseur sur ces erreurs.
bien à vous

[tchize_]

ok, on dirait que la java que tu as associée à ton projet n'existe pas. Du coup il ne trouve pas les classes de bases de java, du coup tout foire. Regarde dans les préférence de ton workspace, dans la partie installed jre, si ton Java 8 est correctement référencé.

[cürüs]

Bonjour à vous voici ce que j'obtiens lorsque je vais sur Réfèrence > Installed JREs

que faut-il faire pour que cela soit pris en compte?

[tchize_]

clique sur java SE-1.8, il doit y avoir au moins un "compatible JRE" affichée à droite
clique sur installed JRE, tu dois au moins y trouver une java 1.8
Vérifie que les dossier mentionnés sont correct et pointent bien vers une jre/jdk correctement installée. A défaut, réinstalle.
Vérifie aussi quand tu regarde le détaile da JavaSE-1.8 dans ton buildpath, que cela mentionne bien une 15aines de jar situés dans la jre

[cürüs]

merci, je vais télècharger une nouvelle version du JDk 8, car je ai installé la JDK-8 via le terminale avec la commande suivante sudo apt-get install openjdk-8-jdk, je ne comprend pas pourquoi cela ne fonctionne pas.j'installe et j'applique votre procédure
merci et à plus

[andry.aime]

Bonjour,

Sur l'imprime écran que tu as posté, clique sur "Installed JREs" et coche sur un JRE si il existe, sinon, tu cliques sur le bouton add et ajoute ensuite le répertoire de ton JRE.

A+.

[cürüs]

Salut à vous et merci, j'ai suivi vos indications et j'ai pu configurer la java-8-openjdk-amd64, les erreurs on disparu. mais parcontre je fais face à un nouveau problème lorsque je veux executé un simple hello world avec REST de Spring

je sais pas comment gerer cette erreur, merci d'avance pour votre aide

[tchize_]

En commençant pas nous copier coller le message d'erreur. Ta capture d'écran ne nous sert à rien.

[andry.aime]

Au lieu de faire un imprime écran, copie tes codes et les erreurs en utilisant les balises appropriées ([code] et/ou [quote]). Regarde le mode d'emploi de l'éditeur ici.

EDIT: tchize_ m'a devancé pendant que je cherchai le mode d'emploi de l'editeur

A+.

[cürüs]

Ok, tout d'abord merci pour votre attention voici mon code
ceci est la classe main générer automatiquement lors de la création du projet

Code :

import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class DemoApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

et ceci est ma classe Rest que j'ai crée pour afficher un Hello-world via le navigateur

}

voici l'arborescence du projet


et voici le message d'erreur que renvois la console lorsque j'execute via spring boot App

Bonjour,

Utilise la balise [quote] pour citer les erreurs.

C'est que tu n'as pas de DataSource.
Si t'as besoin d'un dataSource, ajoute dans ton application.propeties

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
spring.datasource.url=l'url de la base
spring.datasource.username=utilisateur de la base
spring.datasource.password=mot de passe pour l'utilisateur

Sinon, ajoute sur la classe DemoApplication l'annotation

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

A+.

Bonjour,

@SpringBootApplication est l'équivalent de l'utilisation des annotation @Configuration, @ComponentScan, @EnableAutoConfiguration.
Donc tu ne dois pas utiliser @SpringBootApplication avec les autres annotations. Avec @SpringBootApplication, tu peux utiliser des attributs de @ComponentScan et @EnableAutoConfiguration avec des alias
Soit tu utilises

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

Soit

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

A+.

mais par contre sur le projet la croix rouge reste, pour tant lorsque je lance le navigateur cela m'affiche belle et bien un Hello world

Et c'est sur quel fichier qui a l'erreur?
S'il n'y a pas d'erreur, Projet --> Clean.
