2.7. Configuring the CSV Reader for Record Sets

  1. To configure a Smooks instance with a CSV reader to read a person record set, use the code below. It will bind the records to a list of person instances. 
    
Smooks smooks = new Smooks();
 
smooks.setReaderConfig(new CSVReaderConfigurator("firstname,lastname,gender,age,country")
                  .setBinding(new CSVBinding("people", Person.class, CSVBindingType.LIST)));
 
JavaResult result = new JavaResult();
smooks.filterSource(new StreamSource(csvReader), result);
 
List<Person> people = (List<Person>) result.getBean("people");
    Note
    You can also optionally configure the Java Bean. The Smooks instance could instead (or additionally) be configured programmatically to use other visitor implementations to process the CSV record set.
  2. To bind the CSV's records to a list or map of a Java type that reflects the data in your CSV records, use the CSVListBinder or CSVMapBinder classes: 
    
// Note: The binder instance should be cached and reused...
CSVListBinder binder = new CSVListBinder("firstname,lastname,gender,age,country", Person.class);
 
List<Person> people = binder.bind(csvStream);

CSVMapBinder:

// Note: The binder instance should be cached and reused...
CSVMapBinder binder = new CSVMapBinder("firstname,lastname,gender,age,country", Person.class, "firstname");
 
Map<String, Person> people = binder.bind(csvStream);
    If you need more control over the binding process, revert back to using the lower-level APIs.
