我有以下JSON响应，我想知道Java中是否有一种方法可以根据我传递的参数返回属性。
我正在拨打当地的magentohost（/ magento / api / rest / products）来获取以下信息：

作为一个例子，我希望能够返回所有颜色代码为24且价格等于或大于150的产品。我（尝试）实现此目的的代码如下：
public void prepareData(float priceRange, String colour) {
ProductListMapping productListMapping = requestAllProductsFromApi();
Map<String, Product> map = productListMapping.getProductList();
Set<String> keys = map.keySet();
List<String> productNames = new ArrayList<String>();
Iterator<String> iterator = keys.iterator();
while (iterator.hasNext()) {
String key = iterator.next();
System.out.println(map.get(key).getEntity_id()+ " " +map.get(key).getName()+ " " +map.get(key).getColor()+ " " +map.get(key).getPrice());
if (((map.get(key).getPrice() >= (priceRange)) &&
(map.get(key).getColor() == (colourCode)))){
productNames.add(map.get(key).getName());
}else{
System.out.println("The product was not found");
}
}
}
