Description:

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
    - Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'
    - Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'


Action:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.

Connecté à MySQL et changé le pom

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

Ensuite, voici l'application

spring.datasource.url = jdbc:mysql://localhost:1204/test
spring.datasource.username = root
spring.datasource.password = 1204
spring.datasource.driverClassName = com.mysql.jdbc.Driver
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Cette erreur apparaîtra au démarrage, aidez-moi à la résoudre

Veuillez demander à un grand patron de résoudre le problème à distance... cela a pris un demi-mois et je n'ai pas terminé le QAQ

Maintenant, c'est la question : dois-je configurer les beans dans le fichier XML ? Il semble qu'il n'y ait pas de tutoriels. J'ai téléchargé jpa sur le marché mais cela ne fonctionne pas. J'ai toujours eu ce problème. Après avoir lu les tutoriels en ligne, il semble que personne n'ait ce problème... S'il vous plaît, QAQ à distance

Answer 1

Dépendez-vous du pilote JDBC de MySQL dans pom.xml ?

Answer 2

Il y a toujours un problème avec le package externe, vérifiez org.springframework.jdbc

Answer 3

Je n'ai pas vu votre configuration spécifique, donc je ne peux que deviner :
Avez-vous exclu la source de données par défaut de Springboot au lieu d'implémenter une source de données personnalisée ?
Essayez de supprimer include = {DataSourceAutoConfiguration.class} dans @EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class}), ou remplacez-le par une source de données telle que druid ou dbcp.

Answer 4

N'avez-vous pas ajouté de dépendance MySQL ?

Je vous enverrai la configuration que j'utilise récemment pour votre référence :
Je vous enverrai la configuration nécessaire et omettre les autres
Configuration 1.pom.xml :

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

2.configuration de l'application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/vgift
spring.datasource.username=voson
spring.datasource.password=123
spring.datasource.driverClassName=com.mysql.jdbc.Driver
# hibernate 配置
spring.jpa.database=MYSQL
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Answer 5

Re-téléchargez jpa et changez la source. J'ai déjà rencontré ce problème
