com.fasterxml.jackson.dataformat.csv.CsvMapper：限制较少的模式？

Question

CSV ("comma separated values") files, like many data sources, can have aberrations:

• More or fewer fields than there are columns.
• Field values that might present challenges (Eg, containing the field-separator).

Is there some way to configure the jackson CsvMapper so that is operates more liberally: ie, is less restrictive with regard to parsing the data records in CSV files?

Answer 1

I suggest looking into the configuration options for com.fasterxml.jackson.dataformat.csv.CsvMapper . The setup below helped me deal with trailing, unmatched columns (in my case, one or more commas with no field content between them):

CsvMapper csvMapper = (new CsvMapper()).configure(Feature.IGNORE_TRAILING_UNMAPPABLE, true);
