When using IDEA to write a scala program, in order to achieve an error when writing a MYSQL database from a CSV file.

2. Modify the encoding of the database and table
ALTER DATABASE mydb DEFAULT CHARACTER SET utf8;ALTER TABLE mydb.user CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
3. Check the encoding of the database and table
