我正尝试将属性从SearchContent复制到Content:
I am trying to copy properties from SearchContent to Content as:
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);
Sysout正在打印:
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=]

很明显，类Content的selected和renditionInfoFetched字段具有空值，因为它们不在SearchContent中，但是您可以看到Content的所有其他属性为空.我找不到我在做什么错了！
It is obvious to have null values for selected and renditionInfoFetched fields of the class Content, since they are not present in SearchContent but you can see all the other properties of Content is null. I am unable to find what I am doing wrong!
任何指针都将非常有帮助.
Any pointer would be very helpful.
推荐答案
如果要从searchContent复制到内容，则代码应如下所示
If you want to copy from searchContent to content, then code should be as follows
BeanUtils.copyProperties(content, searchContent);
您需要按照上面的代码反转参数.
You need to reverse the parameters as above in your code.
来自 API ，
public static void copyProperties(Object dest, Object orig)
throws IllegalAccessException,
InvocationTargetException)
参数:
orig-获取其属性的Origin bean
orig - Origin bean whose properties are retrieved
