java - 错误: Spring 启动数据库错误“org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration”

Question

我正在使用Spring Boot，Hibernate和My sql，但出现错误。

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“ org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration”的bean时出错：通过构造函数参数0表示的不满意依赖关系；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建在类路径资源[org / springframework / boot / autoconfigure / jdbc / DataSourceConfiguration $ Hikari.class]中定义的名称为'dataSource'的bean时出错：通过工厂方法实例化Bean失败;嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.zaxxer.hikari.HikariDataSource]：工厂方法'dataSource'引发了异常；嵌套的异常是java.lang.IllegalStateException：无法加载驱动程序类：com.mysql.jdbc.Driver

github存储库链接是
https://github.com/dishankgoyal/springsBoot

我怎样才能解决这个问题？

Answer 1

您的mysql jdbc jar似乎已损坏，因此无法加载驱动程序，建议您清除项目或删除.m2存储库可能会有所帮助。

如果maven项目更新无济于事，或者重新启动system/IDE也可能会有所帮助。

或者如果通过IDE添加了任何手动jar，则有时重新安装IDE也可能会有所帮助。

我建议所有这些，因为我在最后运行您的项目并可以正常工作。
