Удалить сообщение от ответа JSON?

Question

Я уже создал успокоительный api, используя java и glassfish, но у меня возникла проблема (а не ошибка).

Когда я получаю ответ JSON от моего API, он отлично работает, но содержит имя компонентов.

{"***countriesBean***":[ //(I need my response without this field) 
    {"CountryID":"3","CountryName":"asdasdasd","DefaultCurrencyID":"0","DefaultLanguageID":"0"},{"CountryID":"16","CountryName":"sddd","DefaultCurrencyID":"1","DefaultLanguageID":"0"},{"CountryID":"1","CountryName":"Lebanon","DefaultCurrencyID":"3","DefaultLanguageID":"0"},{"CountryID":"2","CountryName":"asdasd","DefaultCurrencyID":"0","DefaultLanguageID":"2"} 
] 
}

Answer 2

я не могу проверить вашу проблему без кода.

См основной пример с ожиданием:

public class Customer { 
    String fullName; 
    String email; 

    public String getFullName() { 
    return fullName; 
    } 

    public void setFullName(String fullName) { 
    this.fullName = fullName; 
    } 

    public String getEmail() { 
    return email; 
    } 

    public void setEmail(String email) { 
    this.email = email; 
    } 

    @Override 
    public String toString() { 
    return "Customer{" + 
     "fullName='" + fullName + '\'' + 
     ", email='" + email + '\'' + 
     '}'; 
    } 
} 

..

@Path("/services") 
public class MaisonService { 

    @GET 
    @Path("/test") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Customer getSampleCustomer() { 
     Customer sampleCustomer = new Customer(); 
     sampleCustomer.setFullName("Trinh Toan Trung"); 
     sampleCustomer.setEmail("trinhtoantrung@gmail.com"); 
     return sampleCustomer; 
    } 
.. 

Выход:

{ "электронная почта": "trinhtoantrung@gmail.com" , "fullName": "Trinh Toan Trung"}
