The following is my jrxml code

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="report1" language="groovy" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

    <columnHeader>
        <band height="27" splitType="Stretch">

                <textElement/>
                <text><![CDATA[activePackage]]></text>
            </staticText>
        </band>
    </columnHeader>
    <detail>
        <band height="26" splitType="Stretch">
            <textField>
                <reportElement x="0" y="0" width="100" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$F{activePackage}]]></textFieldExpression>
            </textField>
        </band>
    </detail>
    <columnFooter>
        <band height="45" splitType="Stretch"/>
    </columnFooter>
    <pageFooter>
        <band height="54" splitType="Stretch"/>
    </pageFooter>
    <summary>
        <band height="42" splitType="Stretch"/>
    </summary>
</jasperReport>

The below one is my entity class code:

@Entity
@JsonAutoDetect
@Table(name = "ra_bdr_rating")
public class RaBdrRating extends BaseModel {
@Column(name="active_package")
    private String activePackage;
 public String getActivePackage() {
        return activePackage;
    }
 public void setActivePackage(String activePackage) {
        this.activePackage = activePackage;
    }
}

This is the code in my controller class

public ModelAndView generateHtmlReport(@ModelAttribute("reports") RaReports     model,ModelAndView modelAndView) throws Exception{

    Map<String,Object> parameterMap = new HashMap<String,Object>();

    List<RaBdrRating> packagesList = reportsDao.retrieveAllPackages(model);

    JRDataSource JRdataSource = new JRBeanCollectionDataSource(packagesList);

    parameterMap.put("datasource", JRdataSource);

    //htmlReport bean has ben declared in the jasper-views.xml file
    modelAndView = new ModelAndView("htmlReport", parameterMap);

    return modelAndView;

} 

Here activePackage I have declared as private variable of string type in my entity class. So in my jrxml I am giving the same name with fieldDescription. If I click on preview in iReport there also I am getting the same problem. I am using iReport 4.5.0. Here retrieveAllPackages(model) has a jpa query which retrieves all the packages and returning in the form of list of type RaBdrRating.RaBdrRating is my entity class the one i posted earlier.I am passing that list to the JRBeanCollectionDatasource and placing the datasource in the map.Now i want to display the list in my report.So i am designing a report in iReport in such a way that the field name must match with the attribute name in the entity class.I think now you will get some idea on this.

从字段中删除 fileDescription

<fieldDescription><![CDATA[activePackage]]></fieldDescription>

添加这个“”对我有用

JRDataSource JRdataSource = new JRBeanCollectionDataSource(packagesList, **false**);
