创建名为“dataSource”的 bean 时出错 [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]

Question

i'm getting the following error when i try to debug a Spring boot with Gradle project in Eclipse

Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': 
Unsatisfied dependency expressed through constructor parameter 0; nested exception 
is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'dataSource' defined in class path resource 
[org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]

Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: com.mysql.jdbc.Driver

i've searched a lot, and most of the solutions came from something that is wrong in the application.properties file, but i can not figure what is wrong in mine

server.port=8080
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/dices?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root

Any suggestion?

thanks

Answer 1

您可以尝试将compile("mysql:mysql-connector-java") 添加到 build.gradle 并再次检查吗？

Answer 2

The problem was with eclipse which was not downloading the dependencies. Gradle configuration files were ok
