I am using jackson-dataformat-csv to export a POJO collection to CSV as
follows:
CsvSchema.Builder schemaBuilder = CsvSchema.builder()
.addColumn("id")
.addColumn("name")
etc...CsvSchema schema = schemaBuilder.build().withHeader();CsvMapper mapper
= new CsvMapper();
mapper.enable(CsvGenerator.Feature.ALWAYS_QUOTE_STRINGS);String csv =
mapper.writer(schema).writeValueAsString(pojoCollection);
I want to inspect every field value before it is written to CSV and
optionally modify that value to prevent formulas or other content that
Excel, Sheets, etc might execute. For example if a value starts with @ or =
then
I might prepend the ' character to that value to prevent execution.
How can I configure CsvMapper so that I get a callback for each value
written to CSV?
Thanks!
