ho bisogno di fare rapporto come questo:Come creare più tabelle nel report jasper usando json come origine dati?

Product Name : Product XYZ 

--------------------------------- 
| Item Name | Quantity | Price | 
--------------------------------- 
| Item ABC | 10  | 10 $ | 
| Item BCD | 10  | 1 $ | 

Product Name : Product XYZ2 

--------------------------------- 
| Item Name | Quantity | Price | 
--------------------------------- 
| Item DEF | 15  | 10 $ | 
| Item HIJ | 11  | 1 $ | 

Summary Report 
--------------------------------- 
| Product Name | Total Quantity | 
--------------------------------- 
| Product XYZ | 20    | 
| Product XYZ2 | 26    | 

Il primo problema è "prodotto" lattina 1 a molti.

Il secondo problema è che ho bisogno "Rapporto di sintesi" in basso

Il terzo problema è, questo rapporto dati grezzi provenienti da json, non da query di database.

cosa che ho già provo:

  • creare molti tavolo per il prodotto. Ma questo è fallito perché Jasper crea uno spazio vuoto per la tabella inutilizzata. E la tabella riassuntiva in un'altra pagina con molti spazi vuoti.

  • Sottoreport, come sopra.

Puoi dirmi, per favore, come rendere dinamicamente più tavoli?

EDIT: campione JSON

{"produkList": { 
"items":[ 
    { 
     "nameProduct": "Product XYZ", 
     "itemList": [{ 
      "itemName": "XXXXXXX", 
      "quantity": 50, 
      "price": 50 
     }, 
     { 
      "itemName": "YYYYYYY", 
      "quantity": 50, 
      "price": 50 
     }, 
     { 
      "itemName": "ZZZZZZZZ", 
      "quantity": 50, 
      "price": 50 
     }] 
    }, 
    { 
     "nameProduct": "Product XYZ2", 
     "itemList": [{ 
      "itemName": "AAAAAAAA", 
      "quantity": 50, 
      "price": 50 
     }, 
     { 
      "itemName": "BBBBBBB", 
      "quantity": 50, 
      "price": 50 
     }, 
     { 
      "itemName": "CCCCCCC", 
      "quantity": 50, 
      "price": 50 
     }] 
    } 
    ], 
    "summary":[ 
    { 
     "title": "Summary Report", 
     "summaryReportDetailList": [{ 
      "nameProduct": "Product XYZ", 
      "quantity": 150 
     }, 
     { 
      "nameProduct": "Product XYZ2", 
      "quantity": 150 
     }] 
    } 
    ] 
    } 
}

La struttura sarà

  1. rapporto principale con interrogazione produkList.items che del display Nome prodotto
  2. sottoreport nella detail band con <dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("itemList")]]></dataSourceExpression> per visualizzare la tabella articolo
  3. sottoreport nella summary band con interrogazione produkList.summary.summaryReportDetailList per visualizzare la tabella sintesi

Questo è il risultato

PDF Result

Qui di seguito troverete il 3 jrxml produrre questo risultato, è necessario regolare il percorso per l'origine JSON e il percorso del sottoreport, non dimenticare che è necessario compilare il sottoreport in .jasper prima che il report principale possa essere eseguito.
