    public String getRightsComment() { 
     return rightsComment; 
    } 

    public void setRightsComment(String rightsComment) { 
     this.rightsComment = rightsComment; 
    } 
} 

Ich versuche Eigenschaften kopieren von SearchContent zu Content als:

Content content = new Content();   
Converter converter = new DateConverter(null); 
BeanUtilsBean beanUtilsBean = BeanUtilsBean.getInstance(); 
beanUtilsBean.getConvertUtils().register(converter, Date.class);   
BeanUtils.copyProperties(searchContent, content); 

System.out.println(searchContent); 
System.out.println(content); 

Die Sysout ist Druck:

Es ist offensichtlich, Nullwerte haben für selected und renditionInfoFetched Felder der Klasse Content, da sie in SearchContent nicht vorhanden sind, aber Sie können alle anderen Eigenschaften von Content sehen ist Null. Ich finde nicht, was ich falsch mache!

Jeder Zeiger wäre sehr hilfreich.

scheint, dass die Reihenfolge umgekehrt ist. und du solltest besser beanUtilsBean verwenden. CopyProperties. BeanUtils verwendet eine gemeinsame BeanUtilsBean – farmer1992

Wenn Sie von searchContent zum Inhalt kopieren wollen, dann sollten Code wie folgt

BeanUtils.copyProperties(content, searchContent); 

Sie müssen die Parameter wie oben in Ihrem Code auf der Rückseite.

Von API,

public static void CopyProperties (Object dest, Objekt orig) wirft Illegal, InvocationTargetException)

Parameter: dest - Origin Bohne - Destination Bohne, deren Eigenschaften orig modifizierte wessen Eigenschaften abgerufen werden

http://commons.apache.org/proper/commons-beanutils/apidocs/org/apache/commons/beanutils/BeanUtils.html#copyProperties(java.lang.Object, java.lang.Object)

Nur eine Anmerkung aus Gründen der Vernunft ... Apache und Spring haben beide eine BeanUtils-Klasse mit einer copyProperties-Methode und sie akzeptieren ihre Parameter in umgekehrter Reihenfolge. Apache ist BeanUtils.copyProperties (Ziel, Quelle) und Spring ist BeanUtils.copyProperties (Quelle, Ziel). –

Hinzufügen von Inhalt für Night Owl-Kommentar.Sie können auch die Methode von copyProperties verfolgen und es sollte Ihnen die Reihenfolge, Quelle vs Ziel zu zeigen. Dies ist für Frühling, öffentliche static void copyProperties (Quelle java.lang.Object, Ziel java.lang.Object) – JaredT

Es gibt zwei BeanUtils.copyProperties (Parameter1, Parameter2) in Java.

Eins ist

org.apache.commons.beanutils.BeanUtils.copyProperties (Object dest, Object orig)

Ein weiterer Grund ist

org.springframework .beans.BeanUtils.copyProperties (Objektquelle, Objektziel)

Achten Sie auf die gegenüberliegende Position von Parametern.
