Firebase没有要在课程中找到的序列化属性 [英] Firebase No properties to serialize found on class
问题描述
我试图建立一个类的模型。一个非常简单的类：
package com.glups.model;
导入com.google.firebase.database.IgnoreExtraProperties;
@IgnoreExtraProperties
public class AlumnoFB {
private String nombre;
私人字符串apellidos;
私人字符串telefono;
私人字符串电子邮件;
私有布尔tieneWhatsapp;
私有布尔tieneTelegram;
私有布尔tieneHangouts;
private long formaPago;
private double ratioHora;
私人双重precioHora;
private Double horasCompensadas;
public AlumnoFB（）{
//调用DataSnapshot.getValue（User.class）所需的默认构造函数
}
public AlumnoFB（String
字符串apellidos，
字符串telefono，
字符串电子邮件，
布尔tieneWhatsapp，
布尔tieneTelegram，
布尔tieneHangouts，
Long formaPago ，
Double ratioHora，
Double precioHora，
Double horasCompensadas）{
this.nombre = nombre;
this.apellidos = apellidos;
this.telefono = telefono;
this.email = email;
this.tieneWhatsapp = tieneWhatsapp;
this.tieneTelegram = tieneTelegram;
this.tieneHangouts = tieneHangouts;
this.formaPago = formaPago;
this.ratioHora = ratioHora;
this.precioHora = precioHora;
this.horasCompensadas = horasCompensadas;
}
}
几乎就像Firebase的示例类。 / p>
从getUser（）获取的应用程序用户已经登录到Firebase。
当我调用SetValue时：
AlumnoFB alumno = new AlumnoFB（，，，，false，false，false，（（Integer）FormaPago .INT_NO_PAGADO）.longValue（），0.0，0.0，0.0）;
mDatabase.child（AlumnoFB）。child（ControlClasesFirebase.getUser（）。getUid（））。setValue（alumno）;
一个致命的异常会引发。

我已经检查过类型，并且都被接受。有什么不对？
将变量声明更改为public
public String nombre;
public String apellidos;
public String telefono;
public String email;
public Boolean tieneWhatsapp;
public Boolean tieneTelegram;
public Boolean tieneHangouts;
public Long formaPago;
public Double ratioHora;
public Double precioHora;
public Double horasCompensadas;
I'm bloqued creating a Firebase Database.
I'm trying to model a class. A very simple class:
package com.glups.model;
import com.google.firebase.database.IgnoreExtraProperties;
@IgnoreExtraProperties
public class AlumnoFB {
private String nombre;
private String apellidos;
private String telefono;
private String email;
private Boolean tieneWhatsapp;
private Boolean tieneTelegram;
private Boolean tieneHangouts;
private Long formaPago;
private Double ratioHora;
private Double precioHora;
private Double horasCompensadas;
public AlumnoFB() {
// Default constructor required for calls to DataSnapshot.getValue(User.class)
}
public AlumnoFB(String nombre,
String apellidos,
String telefono,
String email,
Boolean tieneWhatsapp,
Boolean tieneTelegram,
Boolean tieneHangouts,
Long formaPago,
Double ratioHora,
Double precioHora,
Double horasCompensadas) {
this.nombre = nombre;
this.apellidos = apellidos;
this.telefono = telefono;
this.email = email;
this.tieneWhatsapp = tieneWhatsapp;
this.tieneTelegram = tieneTelegram;
this.tieneHangouts = tieneHangouts;
this.formaPago = formaPago;
this.ratioHora = ratioHora;
this.precioHora = precioHora;
this.horasCompensadas = horasCompensadas;
}
}
that is almost like a sample class from Firebase.
Application user obtained from getUser() has been logged on Firebase.
When I call SetValue:
AlumnoFB alumno = new AlumnoFB("", "", "", "", false, false, false, ((Integer)FormaPago.INT_NO_PAGADO).longValue(), 0.0, 0.0, 0.0);
mDatabase.child("AlumnoFB").child(ControlClasesFirebase.getUser().getUid()).setValue(alumno) ;
A fatal exception raises.

I've checked types, and all are accepted. What's wrong?
Firebase require your Pojo to have public variables or getter/setter.
Change variable declarations to public
public String nombre;
public String apellidos;
public String telefono;
public String email;
public Boolean tieneWhatsapp;
public Boolean tieneTelegram;
public Boolean tieneHangouts;
public Long formaPago;
public Double ratioHora;
public Double precioHora;
public Double horasCompensadas;
