I'm in trouble to read a json data that have objects and arrays mixed in his body.
I can read and convert all objects kinds but the forecast node it is an array and I always receive an null as response.
See more details bellow:
My web API give me json response:
{
"location": {
"name": "Brasilia"
},
"current": {
"last_updated": "2019-01-11 19:00",
"condition": {
"text": "Patchy rain possible"
}
},
"forecast": {
"forecastday": [
{
"date": "2019-01-11",
"day": {
"avgtemp_c": 21.4
}
},
{
"date": "2019-01-12",
"day": {
"avgtemp_c": 22.0
}
}
]
}
}
I'm using restTemplate to get the data:
ApiResponse apiResponse = restTemplate.getForObject(uri, ApiResponse.class);
And here is my ApiResponse response estructure:
@JsonIgnoreProperties(ignoreUnknown = true)
public class ApiResponse {
private Location location;
private Current current;
private Forecast forecast;
/*constructors, getters and setters mmited */
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class Location {
private String name;
private String region;
private String country;
private Float lat;
private Float lon;
private String localtime;
/*constructors, getters and setters mmited */
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class Current {
private String last_updated;
private Float temp_c;
private Float precip_mm;
private Condition condition;
/*constructors, getters and setters mmited */
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class Forecast {
public List<Forecastday> forecastday;
/*constructors, getters and setters mmited */
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class Forecastday {
private String date;
private Day day;
/*constructors, getters and setters mmited */
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class Day {
private Float avgtemp_c;
private Float totalprecip_mm;
private List<Condition> condition;
/*constructors, getters and setters mmited */
}
I guess that i am doing the class mapping in a wrong way but i can't see where is the problem.
Can any one help me?
Hey guys i've found the error.
My mapping was really wrong!
In my last class: private List<Condition> condition; isn't a list but a simple object: private Condition condition; and because this i was receiving a Cannot deserialize instance ofjava.util.ArrayListout of START_OBJECT token
