我试图运行一个crud应用程序,但我得到了错误
2020-12-22 09:48:40.787警告83274---[main]configservletwebserverapplicationcontext:上下文初始化期间遇到异常-取消刷新尝试:org.springframework.beans.factory.unsatifiedDependencyException:创建名为“org.springframework.boot.autoconfigure.orm.jpa.hibernatejpaconfiguration”的bean时出错:通过构造函数参数0表示的未满足的依赖关系;嵌套异常为org.springframework.beans.factory.beancreationexception:创建名为'datasource'的bean时出错,该bean在类路径资源[org/springframework/boot/autoconfigure/jdbc/datasourceconfiguration$hikari.class]中定义:通过工厂方法示例化bean失败;嵌套异常为org.springframework.beans.beaninstantiationexception:未能示例化[com.zaxxer.hikari.hikaridatasource]:工厂方法“datasource”引发异常;嵌套异常为java.lang.illegalstateexception:无法加载驱动程序类:org.h2.driver
我无法连接h2。它在application.properties中以红色键入,如下所示。
这也是我完整的pom.xml

按热度按时间hyrbngr71#
您不需要指定
driverClassName
或者database-platform
,在添加h2依赖项之后,spring将使用默认值。你需要这个吗mysql-connector-java
在依赖关系中?
