OpenCSV: How to create CSV file from POJO with custom column headers and custom column positions?

Question

I have created a MappingsBean class where all the columns of the CSV file are specified. Next I parse XML files and create a list of mappingbeans. Then I write that data int

Answer 1

Try something like below:

private static class CustomMappingStrategy extends ColumnPositionMappingStrategy {

    String[] header;

    public CustomMappingStrategy(String[] cols) {
        header = cols;
    }

    @Override
    public String[] generateHeader(T bean) throws CsvRequiredFieldEmptyException {
        return header;
    }
}

Then use it as follows:

String[] columns = new String[]{"Name", "Age", "Company", "Salary"};
        CustomMappingStrategy mappingStrategy = new CustomMappingStrategy(columns);

Where columns are columns of your bean and Employee is your bean
