Example of resource

    @GET
    @Produces("text/csv")
    public Response get() {
        return Response.ok(repository).build();
    }

    @POST
    @Consumes("text/csv")
    public Response post(List<Person> persons) {
        repository.addAll(persons);
        return Response.ok().build();
    }
}

CSV Schema configuration

• Define order of CSV columns :

@CsvSchema(columns = { "firstName", "lastName", "age" })
public class Person {

    private String firstName;
    private String lastName;
    private int age;
}

• Default CSV separator is : ;. If you want to use another separator, you can override it :

@CsvSchema(separator=',',
           columns = { "firstName", "lastName", "age" })
public class Person {

    private String firstName;
    private String lastName;
    private int age;
}

• You can skip the first row during parsing (default is false). Needed to support CSV-like file formats that include additional non-data content before real data begins)

@CsvSchema(separator=',',
           columns = { "firstName", "lastName", "age" },
           skipFirstDataRow = true)
public class Person {

    private String firstName;
    private String lastName;
    private int age;
}
