如何在Android Retrofit中忽略JSON元素

问题描述

我正在开发一个Android应用，该应用使用Android Retrofit发送JSON(它将POJO类转换为JSON).它工作正常，但是在发送JSON时，我需要忽略POJO类中的一个元素.

I am developing an Android App which is sending a JSON using Android Retrofit (it converts a POJO class in a JSON). It is working fine, but I need to ignore in the sending of JSON one element from the POJO class.

有人知道任何Android Retrofit批注吗?

Does anyone know any Android Retrofit annotation?

示例

POJO类:

public class sendingPojo
{
   long id;
   String text1;
   String text2;//--> I want to ignore that in the JSON

   getId(){return id;}
   setId(long id){
     this.id = id;
   }

   getText1(){return text1;}
   setText1(String text1){
     this.text1 = text1;
   }

   getText2(){return text2;}
   setText2(String text2){
     this.text2 = text2;
   }


}

接口发送方ApiClass

 public interface SvcApi {

 @POST(SENDINGPOJO_SVC_PATH)
 public sendingPojo addsendingPojo(@Body sendingPojo sp);

}

有什么想法如何忽略 text2 ?

推荐答案

如果您不想使用new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create()，我发现了另一种解决方案.

I found an alternative solution if you don't want to use new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create() .

只需在要忽略的变量中包含transient.

Just including transient in the variable I need to ignore.

因此，POJO类终于实现了:

So, the POJO class finally:

public class sendingPojo {
    long id;
    String text1;
    transient String text2;//--> I want to ignore that in the JSON

    getId() {
        return id;
    }

    setId(long id) {
        this.id = id;
    }

    getText1() {
        return text1;
    }

    setText1(String text1) {
        this.text1 = text1;
    }

    getText2() {
        return text2;
    }

    setText2(String text2) {
        this.text2 = text2;
    }
}
