Overriding BeanPropertyRowMapper to Support JodaTime DateTime

Question

My Domain object has couple of Joda-Time DateTime fields. When I\'m reading database values using SimpleJdbcTemplate:

Patient patient = jdbc.

The answer of @Sean Patrick Floyd is perfect until you do not have many many custom types.

Here it a generalized, configurable based on usage extension:

public class CustomFieldTypeSupportBeanPropertyRowMapper extends BeanPropertyRowMapper {
  private Map, Handler> customTypeMappers = new HashMap, Handler>();

  public CustomFieldTypeSupportBeanPropertyRowMapper() {
    super();
  }

  public CustomFieldTypeSupportBeanPropertyRowMapper(Class mappedClass, boolean checkFullyPopulated) {
    super(mappedClass, checkFullyPopulated);
  }

  public CustomFieldTypeSupportBeanPropertyRowMapper(Class mappedClass) {
    super(mappedClass);
  }

  public CustomFieldTypeSupportBeanPropertyRowMapper(Class mappedClass, Map, Handler> customTypeMappers) {
    super(mappedClass);
    this.customTypeMappers = customTypeMappers;
  }

  @Override
  protected Object getColumnValue(ResultSet rs, int index, PropertyDescriptor pd) throws SQLException {
    final Class current = pd.getPropertyType();
    if (customTypeMappers.containsKey(current)) {
      return customTypeMappers.get(current).f(rs, index, pd);
    }
    return super.getColumnValue(rs, index, pd);
  }

  public void addTypeHandler(Class class1, Handler handler2) {
    customTypeMappers.put(class1, handler2);
  }

  public static interface Handler {
    public Object f(ResultSet rs, int index, PropertyDescriptor pd) throws SQLException;
  }
}
