在Spring中使用CrudRepository接口获取数据时出现以下错误

我已经检查过Stack Trace中有3种异常：

  1. 创建类路径资源org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class中定义的名为“entityManagerFactory”的bean时出错
  2. 由: javax.persistence.PersistenceException: PersistenceUnit:默认无法构建Hibernate SessionFactory引起
  3. 导致: org.hibernate.tool.schema.spi.SchemaManagementException:无法对JDBC目标执行模式管理(创建序列)
  4. 由: org.postgresql.util.PSQLException: ERROR:架构丹被拒绝的权限引起

我需要更多关注的是最后一个还是第一个，如果最后一个也意味着我的spring.datasource.url =这个Url不正确，或者我没有访问数据的权限？

异常1、2和3是异常4的包装器。因此，如果您解决了异常4 (org.postgresql.util.PSQLException: ERROR:许可被拒绝模式dan)，其他三个异常也会消失。

Exception 4表示，您没有运行运行任何语句所需的权限，因此您需要查看对dan模式的权限。
