Support for invalid dates

[pramodbindal]

Hi,
My input CSV is not controlled by me. it is coming from some upstream server. I need to parse the CSV and there is fair chances for invalid values.
Currently If there is any value which is not convertible to target datatype then i get JacksonException. There should be an option to ignore such values and move on to next value.

this is my exception.

Please register a custom deserializer for such type. It can take whatever action necessary.

It would be a great help if you can share me an example.
I am facing same issue for other data type BigDecimal too

Thanks.

@pramodbindal I am sure you can google for "jackson custom deserializers" -- there are many jackson tutorials in existence. In general, here:

https://github.com/FasterXML/jackson-docs

is a list of reported documentation, and I'd be happy to add links to other resources as well.

Deserializers are not format-specific wrt handling (that is, they are registered same way, have same API), so tutorials for json should work as examples.
