java - Java Spring错误创建名称为bean的bean

Question

运行gradle bootRun时出现以下错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.

经过一些研究后，我不确定是否需要添加到application.properties或它完全不同。
我不确定我是否想念一些东西。

Answer 1

您需要在spring boot application.properties文件中指定数据库驱动程序属性。

spring.jpa.datasource.database-platform=<your hibernate dialect>
spring.jpa.datasource.driverClassName=<sql driver class name>
spring.jpa.datasource.url=<your url>
spring.jpa.datasource.username=<username>
spring.jpa.datasource.username=<password>

这里发生的是，Spring Boot根据您在application.properties文件中设置的属性做出默认假设。当spring boot已经基于属性文件为您完成配置时，您不应显式声明数据库配置。
