MyBatis PersistenceException: Unknown column 'email' in 'where clause' - MySQL Error

Possible solution: The error message indicates that the column 'email' is not found in the 'admin' table. Check the database schema to make sure that the column exists and is spelled correctly. If it does not exist, add it to the table. If it is misspelled, correct the spelling in the SQL query. Also, make sure that the SQL query matches the expected parameter types and number of parameters.
