無法在apache駝峯上使用outPutClass進行深度映射

Question

我有一個要求，我必須從兩個不同的源文件中讀取數據，一個來自文件，另一個來自數據庫，然後在聚合器中執行一些操作，然後寫入輸出到一個文件。

我能夠讀取文件，但從數據庫中讀取文件後，我必須將文件轉換爲一個bean。我無法做到。

下面是我的代碼：

路線：

from("file:{{InputFileDir1}}?noop=true") 
       .routeId("readInputFiles") 
       .unmarshal() 
       .bindy(BindyType.Csv,Job9.class) 
       .enrich("direct:resource", batchLogRecords) 
       .marshal() 
       .bindy(BindyType.Csv, ClubbedJob.class) 
       .to("file:{{OutPutDir}}?fileName={{FinalJoinedFile}}") 
       .log(LoggingLevel.INFO,"Left Join Complete") 
       .end(); 
     from("direct:resource") 
       .setBody(simple("SELECT D.DC LOC,D.DEPT,D.CLASS as CLAS,D.ITEM,D.ITEM_CSPK, 'P' as Dummy FROM db2prod.ITEM_DC D,db2prod.FRTB_ITEM_W E WHERE D.DEPT=E.DEPT AND D.CLASS=E.CLASS AND D.ITEM=E.ITEM AND D.DC_I=E.LOC AND E.ALOC_PRCS='9987' with ur;")) 
       .to("jdbc:dataSourceDB2?outputClass=com.tgt.fff.beans.LookUpJob9") 
       .process(convertToObject) 
       .end(); 

上述路線讀取文件，並用通過轉換成一個對象查詢返回結果集豐富。

.to("jdbc:dataSourceDB2?outputClass=com.tgt.fff.beans.LookUpJob9") 

LookUpJob9.java

@Component 

public class LookUpJob9 { 


    CompositeKey compositeKey; 

    String itemCspk; 

    String dummy; 

    --------getters & setters----------- 

} 

的CompositeKey是包含含有複合鍵4個字段的類。

現在的問題是outputClass屬性無法進行深度映射。 它能夠映射itemCspk和dummy，但無法映射CompositeKey類中的字段。

我收到以下異常：

java.lang.IllegalArgumentException: Cannot map all properties to bean of type class com.tgt.fff.beans.LookUpJob9. There are 4 unmapped properties. {locI=553, deptI=2, clasI=0, itemI=3}

當我用bindy上面的類，我用@link與CompositeKey類將兩者結合起來。有沒有什麼類似的方法可以用JDBC來實現它。

Answer 1

當前不支持嵌套/深度映射。這需要駝峯-jdbc組件中的一些修改工作來支持這一點。
