Bindy skipping empty csv files

Question

I built a camel route that unmarshals a csv file using camel bindy and writes the contents to a database. This works perfectly apart from when the file is empty, which by the looks of it will happen a lot. The file does contain csv headers, but no relevant data eg:

CODE;CATEGORY;PRICE;

In this case the following error is thrown:

java.lang.IllegalArgumentException: No records have been defined in the CSV

I tried adding allowEmptyStream = true to the bindy object that I use for unmarshalling. This however does not seem to do much, as the same error appears.

Any ideas on how to skip processing these empty files is very welcome.

Answer 1

In your use case, the option allowEmptyStream must be set to true at Bindy DataFormat level, as next:

BindyCsvDataFormat bindy = new BindyCsvDataFormat(SomeModel.class);
bindy.setAllowEmptyStream(true);

from("file:some/path")
    .unmarshal(bindy)
    // The rest of the route
