How to generate mapping files in Hibernate?

In Hibernate, there are two ways to generate mapping files.

1. Generate mapping files using Hibernate tool: Hibernate provides tools such as Hibernate Tools or Hibernate Reverse Engineering tool, which can automatically generate mapping files through reverse engineering. These tools can generate corresponding mapping files based on the database table structure. You can specify the database connection information and table names for generating mapping files by configuring the tool parameters.
2. Manually writing mapping files: If you do not want to use automatically generated mapping files, you can also manually write mapping files. Mapping files are typically in XML format and need to include the mapping relationships between entity classes and database tables, including the mapping relationships between properties and columns, mapping relationships of primary keys, etc. You can manually write mapping files based on the mapping rules and syntax provided by Hibernate.

Whether you generate mapping files automatically or manually write them, you need to specify the path to the mapping files in the Hibernate configuration file so that Hibernate can load and use them.
