Error phenomenon: Startup times are wrong and cannot be converted to an internal representation, as shown in the figure below.

Reason: The error is that the Hibernate configuration file cannot be converted into information for the corresponding table in the database.
In general, Hibernate field attributes are wrongly written, String type is written as long, number type is written as String and so on, causing the database content cannot be converted to Java class.

Corresponding method: Check that the database table field and the entity class attribute types are the same
