下面列出了怎么用javax.validation.valueextraction.ValueExtractor的API类实例代码及写法，或者点击链接到github查看源代码。
@Override
public T addValueExtractor(ValueExtractor<?> valueExtractor)
{
return delegate.addValueExtractor(valueExtractor);
}
@Override
public ValidatorContext addValueExtractor(ValueExtractor<?> valueExtractor)
{
return null;
}
@Override
public void extractValues(Profile originalValue, ValueExtractor.ValueReceiver receiver) {
receiver.value(null, originalValue.getCompanyName());
}
