杰克逊在数组
通常情况下，我对使用
的数组内的对象做得很好models = mapper.readValue(jSONstream, mapper.getTypeFactory()
.constructCollectionType(List.class, Model.class));
但是这个HTTP请求会向我发回类似的内容。

这是数组中的数组。我不知道如何正确解析它，我已经尝试了很多不同的方法来做到这一点。任何帮助表示赞赏。
P / S：这是所有getter和setter的模型。
Model.class
public class ModelRoutes {
List<ModelRoute> modelRoutes;
public class ModelRoute {
long lenght;
long duration;
List<Leg> legs;
public class Leg {
long lenght;
long duration;
String type;
String code;
List<Locs> locs;
List<Shape> shapes;
public class Locs {
Coord coord;
long arrTime;
long depTime;
String name;
long code;
String shortCode;
String stopAddress;
public class Coord {
double x;
double y;
}
}
public class Shape{
double x;
double y;
}
}
}
}
此外，对此运行单元测试会给出错误com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of com.avior.aviorandroid.Models.ModelRoutes out of START_ARRAY token at line: 1, column: 2
2 个答案:
答案 0 :(得分：1)
您还需要一个clases才能在ModelRoute和Leg之间映射对象。
看看你的json的照片：
JSON - ＆gt;列表＆lt; ModelRoute＆LT; NEW_Object＆LT;腿......
答案 1 :(得分：0)

我将如下所示定义我的模型类，并使用组合来构造最外层的元素。
public class OuterMostClass {
private double length;
private int duration,
private InnerElement[] innerElements;
}
public class InnerElement {
private double length;
private double duration;
private String type;
private Location[] locs;
}
public class Location {
private Coordinates coords;
private Date arrTime;
private Date depTime;
private String name;
}
public class Coordinates {
private int x;
private int y;
}
请添加必要的getter和setter（使用任何IDE功能）并更正一些名称.Http请求的结果是OuterMostClass数组。所以你将得到一个OuterMostClass []数组。
