     return rightsComment; 
    } 

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

我想屬性複製從SearchContent到Content爲：

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);

的Sysout是打印：

com.mhis.dam.service.search.bean.SearchContent[id=52906,docName=MHIS043570,docType=Images,docTitle=preview_1_8,docAuthor=sysadmin,securityGroup=Internal,docAccount=WF/017/DAM/000,revLabel=1,profile=DAMMedia,workflowStage=com.mhis.dam.generic.bean.LabelValueBean[label=Published,value=published],createDate=Fri Oct 18 15:30:35 IST 2013,inDate=Fri Oct 18 15:30:35 IST 2013,originalName=Vintage 2004 Gift Box & Bottle Black - hires.jpg,format=image/jpeg,extension=jpg,fileSize=2106898,author=Arjan,entity=com.mhis.dam.generic.bean.LabelValueBean[label=Dom Perignon,value=WF/017/DAM],brand=com.mhis.dam.generic.bean.LabelValueBean[label=Dom Perignon,value=WF/017/DAM/001],product=com.mhis.dam.generic.bean.LabelValueBean[label=Blanc,value=17_1_blanc],collection=com.mhis.dam.generic.bean.LabelValueBean[label=Pack shot,value=pack_shot_dp],subCollection=com.mhis.dam.generic.bean.LabelValueBean[label=Bottle shot,value=ps_bottle_dp],description=preview_1,program=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],vintage=,model=,restrictedZone=,event=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],language=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],geographicLocation=,watermark=,pageNumber=0,summary=,agentName=,commissionedByName=Nicolas,commissionedByDepartment=,bestOf=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=0],mediaLocation=,fullRights=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=1],mediaUsage=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],rightsEndDate=<null>,geographicRights=,evinConformity=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=2],contactReference=,publicationScope=com.mhis.dam.generic.bean.LabelValueBean[label=Full public usage,value=fullPublic],rightsComment=]

很明顯，對於有selected和空值類Content的renditionInfoFetched領域，因爲它們不存在於SearchContent但可以看到的Content的所有其他屬性一片空白。我無法找到我做錯了什麼！

任何指針都會非常有幫助。

似乎param順序被顛倒。你最好使用beanUtilsBean。 copyProperties。 BeanUtils正在使用一個共享beanUtilsBean – farmer1992

愚蠢的錯誤:( –

如果你想從searchContent複製到內容，那麼代碼應該如下

BeanUtils.copyProperties(content, searchContent);

你需要扭轉的參數如上在你的代碼。

從API，

公共靜態無效copyProperties（對象DEST，對象原稿）拋出IllegalAccessException，的InvocationTargetException）

參數： DEST - 目的地豆，其屬性被修改原稿 - 原產地豆其屬性被檢索

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

只是爲了理智的緣故... Apache和Spring都有一個帶有copyProperties方法的BeanUtils類，它們以相反的順序接受它們的參數Apache的BeanUtils.copyProperties（target，源代碼），Spring's是BeanUtils.copyProperties（源代碼，目標代碼） –

爲Night Owl的評論添加內容您還可以跟蹤copyProperties的方法，它應該顯示參數順序，源代碼和目標代碼這是春季，公開static void copyProperties（java.lang.Object source，java.lang.Object target） – JaredT

Java中有兩個BeanUtils.copyProperties（parameter1，parameter2）。

一個是

org.apache.commons.beanutils.BeanUtils.copyProperties（對象DEST，對象原稿）

另一個是

org.springframework .beans.BeanUtils.copyProperties（Object source， Object target）

注重參數相反位置。
