MySql does not properly support SQL catalogs and schema. If you run the create schema command in MySql, it actually creates a database - and the JDBC driver reports it back as a catalog. But MySql syntax does not support the standard catalog..table SQL syntax.
For this reason, it is best to not specify either catalog or schema in generator configurations. Just specify table names and specify the database in the JDBC URL.
If you are using version 8.x of Connector/J you may notice that the generator attempts to generate code for tables in the MySql information schemas (sys, information_schema, performance_schema, etc.) This is probably not what you want! To disable this behavior, add the property nullCatalogMeansCurrenttrue to your JDBC URL.
For example: jdbcConnection driverClasscom.mysql.jdbc.Driver connectionURLjdbc:mysql://localhost/my_schemauserIdmy_user passwordmy_passwordproperty namenullCatalogMeansCurrent valuetrue //jdbcConnection
