我需要这样做报告:
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 |
第一个问题是“产品”可以是1对多。
第二个问题是我需要在底部的“摘要报告”
第三个问题是,这个原始数据报告来自json
,而不是从查询到数据库。
我已经尝试了什么:
为产品创建许多表。但这失败了因为jasper为未使用的表创建了空白空间。而其他页面中的摘要表有很多空白区域。
子报告,与上述相同。
请告诉我,如何动态制作多个表格?
编辑:示例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
}]
}
]
}
}
答案 0 :(得分:7)
结构将是
produkList.items
的主报告
detail
在<dataSourceExpression><![CDATA[((net.sf.jasperreports.engine.data.JsonDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("itemList")]]></dataSourceExpression>
范围内进行子报告以显示项目表 summary
个频段中使用查询produkList.summary.summaryReportDetailList
进行子报告,以显示摘要表 这是结果
下面你会发现3 jrxml产生这个结果,你需要调整json源的路径和子报告的路径,不要忘记在主报告可以在.jasper
之前编译子报告运行
