[英]Android , Deserialize JSON Array that have different types using Jackson
I have an Android application that uses Jackson to deserialize the data and I face troubles in creating the pojo for this json string: 我有一个使用Jackson来反序列化数据的Android应用程序,在为此json字符串创建pojo时遇到了麻烦:
{
"response": [{
"view": "ticker",
"items": []
}, {
"view": "note",
"note": "This is a note"
}, {
"wn": "bla",
"sd": "bla bla",
"tf": 28,
"rh": 22,
"ws": 9,
"ti": "14:00",
"view": "hbhi"
}]
}
I create the following pojos: 我创建以下pojos:
TickerModel.java TickerModel.java
public class TickerModel implements Serializable {
@JsonProperty("view")
private String view ;
@JsonProperty("items")
private String items;
public String getView() {
return view;
}
public void setView(String view) {
this.view = view;
}
public String getItems() {
return items;
}
public void setItems(String items) {
this.items = items;
}
} }
NoteModel.java NoteModel.java
public class NoteModel implements Serializable {
@JsonProperty("view")
private String view ;
@JsonProperty("note")
private String note;
public String getView() {
return view;
}
public void setView(String view) {
this.view = view;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note;
}
} }
any ideas on how to to do deserialize this JSON using Jackson? 关于如何使用杰克逊反序列化此JSON的任何想法?
No need to create two separate pojo's, you can have pojo like below - 无需创建两个单独的pojo,您可以像下面这样创建pojo-
public class Response {
@JsonProperty("view")
private String view;
@JsonProperty("items")
private List<Object> items = new ArrayList<Object>();
@JsonProperty("note")
private String note;
@JsonProperty("wn")
private String wn;
@JsonProperty("sd")
private String sd;
@JsonProperty("tf")
private Integer tf;
@JsonProperty("rh")
private Integer rh;
@JsonProperty("ws")
private Integer ws;
@JsonProperty("ti")
private String ti;
//setters //getters
}
Note: Since items is an array in your json, you should map it with array-list of type objects. 注意:由于items是json中的数组,因此应使用类型对象的array-list映射它。 Also you can get pojo's craeted online if you have json data - http://www.jsonschema2pojo.org/
如果您拥有json数据,也可以在线获取pojo的信息-http: //www.jsonschema2pojo.org/
