没有名称为X的EntityManager的持久性提供程序错误

标签： java spring hibernate jpa spring-data-jpa

我正在尝试使用mvc和hibernate运行一个空的Spring应用程序。 我被困在休眠状态，由于某种原因，我不断收到以下错误。 从像休眠这样的日志看来似乎尝试连接到数据库，但是失败了，我不知道有什么问题。 我使用的数据库是MySQL8的本地实例。设置（例如字符编码，时区等）正确，使用JDBC连接它也没有问题。

Error creating bean with name 'entityManagerFactory' defined in pl.coderslab.app.AppConfig: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: No Persistence provider for EntityManager named tesPersistenceUnit
