Java 使用Jaspersoft和Spring迭代Json对象中的数组

java json jasper-reports

Java 使用Jaspersoft和Spring迭代Json对象中的数组,java,json,jasper-reports,Java,Json,Jasper Reports,我正在尝试将一个Json从spring解析到Jaspersoft，因此我做了以下工作： JSONObject json = new JSONObject(); json.put("t", tickets); json.put("totalAmount", df.format(totalAmount)); mapper.writeValue(jsonFile, json.toMap()); JsonDataSource source = n

我正在尝试将一个Json从spring解析到Jaspersoft，因此我做了以下工作：

JSONObject json = new JSONObject();
json.put("t", tickets);
json.put("totalAmount", df.format(totalAmount));
        
mapper.writeValue(jsonFile, json.toMap());
JsonDataSource source = new JsonDataSource(jsonFile);
JasperPrint print = JasperFillManager.fillReport(report, parameters, source);
这将为我创建一个Json，其中包含以下信息：

{
    "t": [
        {
            "id": 5,
            "number": 666,
            "taxpayer": {
                "name": "rodrigo",
                "idAtmTaxpayer": null,
                "cuit": "20408980675",
                "email": "rodrigo.rodriguez@marandu.com.ar"
            }
        }
    ],
    "totalAmount": "195626,92"
}
所以，我的疑问是：我如何在Jaspersoft中显示这些信息，而不使用子报表

如果有人能帮助我，我将非常感激

将表达式与字段相等的

放入报告的某个栏位中，例如详细栏位

这对我有用。显然，因为您使用t作为数据的根，“totalAmount”字段将不起作用

谢谢你，但我已经这么做了，并返回null，因为我无法识别Json对象中的属性“idAt纳税人”。我在JasperStudio中使用的数据与字段和表达式完全相同。当您传递数据源时，这可能是在运行时发生的。谢谢，但我已经这样做了，并返回null，因为我无法识别Json对象中的属性“idAt纳税人”。在JasperStudio中，它使用您的数据和完全相同的字段和表达式为我工作。当您传递数据源时，可能是在运行时。
