JSONレスポンスからファイルを削除しますか？

Question

私はすでにJavaとglassfishを使って安らかなAPIを作成していますが、私は問題に直面しています（エラーではありません）。

私は私のAPIからJSONレスポンスを受信すると、それが正常に動作しますが、豆の名前が含まれています。

{"***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"} 
] 
}

これは、私はあなたのコードなしであなたの問題を検証することはできません豆

Answer 2

です。

あなたの期待に基本的な例を参照してください。

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; 
    } 
.. 

出力：

{ "電子メール"： "trinhtoantrung@gmail.com" 、 "のfullName"： "チンToanチュン"}
