[英]Excel datasource in JasperReports/iReport: Unable to get value for field 'Date' of class 'java.sql.Date'
I've used an Excel file as datasource for building report with iReport . 我使用Excel文件作为数据源来使用iReport构建报表。 The xls file contains dates yyyy-MM-dd format.
xls文件包含日期yyyy-MM-dd格式。
I've set the Date field class to java.sql.Date and I click on preview in iReport . 我已将Date字段类设置为java.sql.Date ,然后单击iReport中的预览。 There is an error:
Unable to get value for field 'Date' of class 'java.sql.Date'.
有一个错误:
Unable to get value for field 'Date' of class 'java.sql.Date'.
I have tried with java.util.Date too. 我也尝试过java.util.Date 。 Do you have any ideas?

As you can see from the image above I've set yyyy-MM-dd
format for date field in DS definition. 从上图中可以看出,我在DS定义中为日期字段设置了
yyyy-MM-dd
格式。
