Question

如何使用java pojo类反序列化下面的json响应。

JSON响应

"details": 
  {
     "distance": 14745,
     "km": 14.745,
     "steps": 16804,
     "active_time": 11927,
     "longest_active": 2516,
     "inactive_time": 32760,
     "longest_idle": 27180,
     "calories": 1760.30480012,
     "bmr_day": 1697.47946931,
     "bmr": 1697.47946931,
     "bg_calories": 1099.9439497,
     "wo_calories": 388.506116077,
     "wo_time": 11484,
     "wo_active_time": 3902,
     "wo_count": 2,
     "wo_longest": 2516,
     "tz": "America/Los Angeles",
     "tzs": 
     [
        [1384963500, "America/Phoenix"],
        [1385055720, "America/Los_Angeles"]
     ]
 }

我已经编写了下面的pojo catch用于反序列化JSON响应。

Response.java

public class Response {

private Distance distance;
}

Distance.java
 public class Distance{ private int distance;
    private double km;
    private int steps;
    private int active_time;
     private int longest_active;
    private int inactive_time;
    private int longest_idle;
    private int calories;
    private int bmr_day;
    private int bmr;
    private int bg_calories;
    private int wo_calories;
    private int wo_time;
    private int wo_active_time;
   private int wo_count;
   private int wo_longest;
    private int sunrise;
    private int sunset;
    private String tz;
    private String[] tzs;
    private String hourly_totals;
  }

我收到以下异常，

Can not deserialize instance of java.lang.String out of START_ARRAY token
atSource: java.io.PushbackInputStream@e6819e;(through reference chain: Details["tzs"]); 
nested exception is com.fasterxml.jackson.databind.JsonMappingException: 
Can not deserialize instance of java.lang.String out of START_ARRAY token

如何克服这一点。

Answer 1

您需要一个类来匹配时区数组

public class TimeZoneClass {
    private Object[] tz_values ;
}

并在

更改此

private String[] tzs;

到这个

private TimeZoneClass[] tzs;

无法反序列化JSON响应
