如何在注释中声明一个Object数组？

Question

鉴于我们无法创建一个annoations层次结构， why-is-not-possible-to-extend-annotations-in-java

如何对一个对象数组进行decalare以存储不同注释的有序列表

public @interface View {
    Object[] elements(); 
//Invalid type Object[] for the annotation attribute View.elements; only 
primitive type, String, Class, annotation, enumeration are permitted
 or 1-dimensional arrays thereof
}
Elements could be @Field, @Tab, @Listing .... but i need to know the order

需要的是我有一个像这样的xml层次结构树

<view id="StkEntranceVoucher" name="StkEntranceVoucher" >
   <listingHeader />
   <listing >
      <ref mode="vp" target="titleText"/>
      <ref mode="vp" target="voucherNumber"/>      
   </listing>
   <panel>
      <tab>
         <tab>            
            <panel>
                 <field name="title" />
            </panel>
            <field name="titleText" />
            <field name="voucherNumber">
        </tab>
      </tab>
    </panel>
</view>

我希望能够在模型上使用anotation配置生成此XML配置： 我已经能够做到这一点

@View(queryFilter=@QueryFilter(orderBy="(?).id.num"), detailSize="580px",
    listingHeader=@ListingHeader(actions="printAll"),
    listing={ "id.num", "reference", "onDate", "fromSection", "supplier", 
                "totalField", "buyOrder.id.num", "buyOrder.onDate", "receiptVcr.id.num", "receiptVcr.onDate",
                "prdExitOrd.id.num", "prdExitOrd.onDate", "invExtract.id.num", "invExtract.onDate" }, 
    tabs={
        @Tab(name="GeneralTab",
        SubTabs={ 
            @SubTab( name="HeaderTab",
                style =@Style(type=StlType.print, colWidths={"50", "400"}, width="450", marginB=2, marginT=8 ),
                fields={                
                    @Field(name="titleText", mode="p", valueExpr="#{bean.mapID( wcx,'reportTitle')}", expectedType=String.class,
                        style=@Style(type=StlType.print, align="center", bold=true, fontSize=16, marginT=20, paddingB=4, paddingL=4, paddingR=4, paddingT=4, textAlign="center", width="200")),             
                    @Field(name="voucherNumberText", mode="p", valueExpr="#{bean.mapID( wcx,'VoucherNum')} : #{(?).id.num} #{bean.mapID( wcx,'VoucherOf')} #{util.format((?).onDate, 'dd/MM/yyyy')}", expectedType=String.class,
                        style=@Style(type=StlType.print, align="center", fontSize=10, textAlign="center" )),                        
                    @Field(name="id.sgSr", mode="", queryFilter=true),  
                    @Field(name="id.num", width="60px", mode="v"),
                    @Field(name="reference"),
                    @Field(name="onDate", mode="v"),                    
                    @Field(name="fromSection"),
                    @Field(name="supplier") }
                ),
            @SubTab( name="ItemsTab", subView=
                @SubView( name="StkEntranceVoucherItem", entityType=StkInputVoucherItem.class, editable=true, 
                    listingFields={ 
                        @Field(name="id.vcr", mode="", queryFilter=true),
                        @Field(name="id.item", width="60px", codeLabel=true),
                        @Field(name="id.item.label", width="150px", mode="rvp"),
                        @Field(name="quantity", width="60px"),
                        @Field(name="id.item.measureUnit", width="50px", mode="rpv"),
                        @Field(name="unitPrice", width="60px"),
                        @Field(name="amount", width="80px", mode="rvp", 
                                calcExpr="#{(?).quantity*(?).unitPrice}"),
                        @Field(name="batch", jsfCpn=JsfCpn.button, linkedViewName="StkInputVoucherBatch", 
                                styleClass="no_padding", width="24px"), 
                        @Field(name="comment", width="100px") }) ),
            @SubTab( name="StkEntranceVoucherTotalTab", style=@Style(css="float:right;"),  
                fields={ 
                    @Field( name="totalField", ofColFooter="amount", mode="rvp",
                        valueExpr="(?).amount", expectedType=Double.class,
                        calcExpr="#{(?)==bean.record?bean.sum(':amount'):(?).amount}") }) 
            })
    })

但它的语法不完全相同，因为我在这里使用了一个@Tab数组和一个@Field数组，但我不能有一个不同注释的数组
