How can I use a MyBatis annotation function where the IN list contains UUIDs?

How can I effectively use a MyBatis annotation function to handle an IN list that contains UUIDs? Specifically, what is the best way to structure the annotation and SQL query to ensure proper handling and comparison of UUID values? Are there any special considerations or potential issues to be aware of when working with UUIDs in MyBatis annotations?

To effectively use a MyBatis annotation function with an IN list containing UUIDs, you can follow these steps:

Define the Mapper Interface: Create a MyBatis mapper interface and annotate it with @Mapper.

Use the @Select Annotation: Use the @Select annotation to define your SQL query. Use the #{#ids} placeholder to handle the IN list of UUIDs.

Handle UUIDs in the Query: Ensure your SQL query correctly handles UUIDs. UUIDs are typically 128-bit numbers, so you should use the appropriate data type in your database (e.g., UUID in PostgreSQL).
