我在Jaunt之后开始使用jackson json,但我无法理解反序列化中的一些细节。
{
success: true,
stickers: [
{
id: "88899",
name: "",
img: ""
},
{
id: "13161",
name: "3DMAX",
img: ""
}
]
}

我的项目中有一个Sticker类
public class Sticker {
@JsonProperty("id")
private String id;
@JsonProperty("name")
private String name;
@JsonProperty("img")
private String imgUrl;
//getters and setters and constructors
}

我想阅读此回复并创建贴纸列表: 列表(贴纸)stickerList;
**另一项任务(如果有可能使用jackson工具),我想在消毒过程中创建HashMap(String,Sticker)而不是List(Sticker)**
如何轻松妥善地做到这一点?
我找到了List的解决方案:我创建了类
public class StickerPage {
@JsonProperty("stickers")
private List<Sticker> stickerList;
public List<Sticker> getStickerList() {
return stickerList;
}
public void setStickerList(List<Sticker> stickerList) {
this.stickerList = stickerList;
}
}
&#13;
并将其用于此:
ObjectMapper objectMapper = new ObjectMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
StickerPage stickerPage = objectMapper.readValue(inputStream, StickerPage.class);
HashMap<String, Sticker> stickerHashMap = new HashMap<>();
for (Sticker sticker : stickerPage.getStickerList()) {
stickerHashMap.put(sticker.getName(), sticker);
}
&#13;
但我认为这看起来很奇怪,你能帮助我完成这项任务吗?
