c# - JSONDeserializer 从 Json 字符串到对象列表

Question

我是 java/android 新手:

我在 wp7 上使用这个对象列表，我想传递给 android，我如何做到这一点:

我的大对象c#:

public class ListCountries
{
    public List<CountriesRepresented> _countriesRepresented { get; set; }
    public List<CountriesOrigin > _countriesOrigin { get; set; }
}

我在 c# 中的其他两个对象:

public class CountriesRepresented
{
    public int CountryID { get; set; }
    public string Designation { get; set; }
    public string Symbol { get; set; }
    public string NomDesignationISO { get; set; }
}

public class CountriesOrigin 
{
    public int CountryID { get; set; }
    public string Designation { get; set; }
    public string Symbol { get; set; }
    public string NomDesignationISO { get; set; }
}

我的java反序列化器:

public Object[] getListCountries()
{

     try {
        HttpClient httpClient = new DefaultHttpClient();

        HttpPost post = new HttpPost(Config.WS_PATH);
        post.setHeader("content-type", "application/json; charset=UTF-8");
        post.addHeader("Client-Application","3601cfde-e440-4a84-a2cc-a402f4c7bd14");        
       HttpResponse resp = httpClient.execute(post);
       String respStr = EntityUtils.toString(resp.getEntity());

        ListCountries _listCountries = new JSONDeserializer().deserialize(ListCountries .class, respStr);

        return _listCountries;

    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

我的java大对象:

public class ListCountries {
public List<CountriesRepresented> _CountriesRepresented;
public List<CountriesOrigin > _CountriesOrigin ;

public List<CountriesRepresented> getCountriesRepresented() {  
    return this._CountriesRepresented;  
  }  

  public List<CountriesOrigin > getCountriesOrigin() {  
    return this._CountriesOrigin ;  
  }


  public void setCountriesRepresented (List<CountriesRepresented> CountriesRepresented) {  
    this._CountriesRepresented = CountriesRepresented;  
  } 
  public void setCountriesOrigin  (List<CountriesOrigin > CountriesOrigin ) {  
    this._CountriesOrigin  = CountriesOrigin ;  
  }

}

我的服务在 WebAPI 上，并给我一个正确的答案示例: `{"PaisesRepresentantes":[{"PaisID":4,"Designacao":"Alemanha","Sigla":"DEU","NomDesignacaoISO": "德国"},{"PaisID":21,.......

Answer 1

你的 Java 类应该是这样的，

public class ListCountries
{
    public List<CountriesRepresented> _countriesRepresented; //Make it private if you want and then you can add getter setter function
    public List<CountriesOrigin > _countriesOrigin;
}

public class CountriesRepresented
{
    public int CountryID; //Make it private if you want and then you can add getter setter function
    public String Designation;
    public String Symbol;
    public String NomDesignationISO;
}

public class CountriesOrigin 
{
    public int CountryID; //Make it private if you want and then you can add getter setter function
    public String Designation;
    public String Symbol;
    public String NomDesignationISO;
}

现有代码的问题是您已将变量声明为 _CountriesRepresented 而应该是 _countriesRepresented 即属性区分大小写，并且这些属性映射到类中声明的变量如果您向这些类中的任何一个添加任何自定义构造函数，请记住添加一个默认构造函数
