示例1: evaluate
import org.jpmml.evaluator.Evaluator; //导入方法依赖的package包/类
@ServiceActivator(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public Object evaluate(Message<?> input) {
Model model = selectModel(input);
Evaluator evaluator = modelEvaluatorFactory.newModelManager(pmml, model);
Map<FieldName, FieldValue> arguments = new LinkedHashMap<>();
List<FieldName> activeFields = evaluator.getActiveFields();
for (FieldName activeField : activeFields) {
// The raw (ie. user-supplied) value could be any Java primitive value
Object rawValue = resolveActiveValue(input, activeField.getValue());
// The raw value is passed through:

// 2) missing value treatment,
// 3) invalid value treatment
// and 4) type conversion
