Object.getText（）在Ireport中的表达式

时间：2016-03-17 08:31:22

标签： groovy jasper-reports

在iReport Designer中，我创建了一个名为address的字段，其类型为java.lang.Object，我创建了一个Text，其表达式为$F{address}.text。 address的数据是java.util.Map，看起来像这样：

["bldgname":null, "barangay":["name":"MINAULON", "objid":"057-01-0013"], "province":"LANAO DEL NORTE", "text":"MINAULON, BACOLOD, \nLANAO DEL NORTE", "unitno":null, "type":"local", "bldgno":null, "pin":null, "city":null, "subdivision":null, "municipality":"BACOLOD", "street":null]

预览报告后，抛出错误说：

如何解决此问题？我使用Groovy作为语言。

1 个答案:

答案 0 :(得分：1)

错误说

net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : 
    Source text : $F{address}.text
...
Caused by: groovy.lang.MissingPropertyException: No such property: text for class: com.rameses.osiris2.reports.ReportDataSource

似乎$ F {address}不是java.util.Map实例，而是com.rameses.osiris2.reports.ReportDataSource对象。

仔细检查数据源中字段的类型。
