我正在为对象中的一个属性使用自定义反序列化器。
public class Leg {
@JsonProperty("carrier_code")
private String carrierCode;
@JsonProperty("carrier_name")
private String carrierName;
@JsonProperty("mode_of_transport")
private String modeOfTransport;
private String provider;
@JsonProperty("leg_id")
private int legId;
@JsonDeserialize(using = PriceContainerDeserializer.class)
@JsonProperty("price_container")
private PriceContainer priceContainer;
private Schedule schedule;
}
我遇到的问题是，除了时间表之外，一切都被解析了。如果我删除了解析调度的自定义反序列化器。我该如何解决这个问题？
这是自定义反序列化器
public class PriceContainerDeserializer extends JsonDeserializer<PriceContainer> {
@Override
public PriceContainer deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
PriceContainer priceContainer = new PriceContainer();
jsonParser.nextValue();
priceContainer.setCurrency(jsonParser.getText());
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
priceContainer.setAmount(jsonParser.getDoubleValue());
return priceContainer;
}
}

修改
所以我的解串器现在看起来像这样
public class PriceContainerDeserializer extends JsonDeserializer<PriceContainer> {
@Override
public PriceContainer deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
PriceContainer priceContainer = new PriceContainer();
jsonParser.nextValue();
priceContainer.setCurrency(jsonParser.getText());
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
priceContainer.setAmount(jsonParser.getDoubleValue());
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
jsonParser.nextValue();
return priceContainer;
}
}
这是最好的方法吗？
