NumberFormatException

Ben bir JSF yedekleme fasulye aşağıdaki yöntemi:NumberFormatException

public List<Rent> getTopMemebers(){ 
    return rentDAO.findByMonthAndYear(MonthReport, YearReport); 
}

bir datatable bu görüntülendiği ediyorum:

<p:dataTable value="#{rentController.topMemebers}" var="item"> 
    <p:column> 
     <h:outputText value="#{item.rentid}"/> 
    </p:column> 
    ... 
</p:dataTable>

Ama şu istisna var:

Yığın izi eklemek için düzenleme yapabilir misiniz? Böylece, uygulamanızın hangi katmanının istisna attığını görebiliriz? – Guillaume

Ve görünümde '# {item.itemid}' kullanan JSF kodunun ilgili kısmı. Tüm bu JPA kodları ve diğer "iyi çalışan" girdiler sorunla ilgisizdir. Sadece soruya gürültü katıyor. – BalusC

ben düzenlendim, lütfen kontrol edin, teşekkürler – MYE

Yani,

<h:outputText value="#{item.rentid}" />

bu neden oluyor:

java.lang.NumberFormatException: For input string: "rentid" 
    ... 
    at javax.el.ArrayELResolver.getValue(ArrayELResolver.java:195) 
    ... 
    at javax.faces.component.UIOutput.getValue(UIOutput.java:168)

Eğer çalıştırdığınız düşünüyorum kodu çalıştırıyor musunuz? ArrayELResolver'un stacktrace'de yer alması, #{item}'un 'unObject[] gibi bir dizi olduğunu gösterir. Dizi değerleri, yalnızca #{item[0]} gibi bir tamsayı dizini ile elde edilebilir, ancak bu istisnaya neden olan rentid#{item.rentid} olarak erişebilirsiniz.

o RentController#getTopMembers() bir List<Rent> değil List<Object[]> döner ve RentController doğru sürümünün #{rentController} yönetilen fasulye olarak ilan edilmiştir emin olun.

evet sağ BalusC 2 parametre entitymanager.createNativeQuery (String, class result) ile yeniden sorgu oluşturmalı; Çok teşekkür ederim – MYE

Rica ederim. – BalusC

Bu aynı sorunu yaşadım. Orm.xml içerisindeki '' etiketinin içinde tanımlanmış SQL vardı. 'Sonuç sınıfı' özniteliğini kaçırıyordu. Bunu ekledikten sonra çalıştı. İnşallah bu ders, problemi googling ettikten sonra (bu gibi) bu yazının üzerine gelen aynı sorunu olan başka birine yardım edecektir. –
