所以我的 bean

public class UserBPSWrapper implements Serializable, IWrapper {

    private String id;
    private String numberSubdivision;
    private String fioAdmin;
    private Date dateReg;
    private String fioClient;
    private String numberPhone;
    private String numberPassport;
    private Date dateRegClient;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getNumberSubdivision() {
        return numberSubdivision;
    }

    public void setNumberSubdivision(String numberSubdivision) {
        this.numberSubdivision = numberSubdivision;
    }

    public String getFioAdmin() {
        return fioAdmin;
    }

    public void setFioAdmin(String fioAdmin) {
        this.fioAdmin = fioAdmin;
    }

    public Date getDateReg() {
        return dateReg;
    }

    public void setDateReg(Date dateReg) {
        this.dateReg = dateReg;
    }

    public String getFioClient() {
        return fioClient;
    }

    public void setFioClient(String fioClient) {
        this.fioClient = fioClient;
    }

    public String getNumberPhone() {
        return numberPhone;
    }

    public void setNumberPhone(String numberPhone) {
        this.numberPhone = numberPhone;
    }

    public String getNumberPassport() {
        return numberPassport;
    }

    public void setNumberPassport(String numberPassport) {
        this.numberPassport = numberPassport;
    }

    public Date getDateRegClient() {
        return dateRegClient;
    }

    public void setDateRegClient(Date dateRegClient) {
        this.dateRegClient = dateRegClient;
    }
}

我打电话报告

JRDataSource dataSource = createReportDataSource(reportRows);
String jasperReportName = newPath + templateXML + ".jasper";

jasperPrint = JasperFillManager.fillReport(jasperReportName, reportParametersMap, dataSource);

private JRDataSource createReportDataSource(Collection reportRows) {
    JRDataSource dataSource;

    if (reportRows == null || reportRows.size() == 0) {
        dataSource = new JREmptyDataSource();
    } else {
        dataSource = new JRBeanCollectionDataSource(reportRows);
    }
    return dataSource;
}
setListToReportDetails((List<UserBPSWrapper>) dataBPSModel.getWrappedData());
