Question

我想将对象列表传递给jasper report中的list组件。我使用dataSourceExpression for list1是新的 net.sf.jasperreports.engine.data.JRBeanCollectionDataSource 和参数类是的java.util.List 。

当我生成报告时，它显示错误，如 java.lang.NoSuchMethodException 。

豆：

public void generateReport() {
    Statement stmt = null;
    ResultSet resultset = null;
    ResultSet resultset1 = null;
    Connection con = null;
    String fromdate = "2013-01-01";
    String todate = "2013-01-31";
    int unitId = 1;
    String driver = "com.mysql.jdbc.Driver";
    String connection = "jdbc:mysql://localhost:3306/compliance?user=root&password=root";
    List<Object> shortnamelist = new ArrayList<Object>();
    try {
        String selectstatement = "CALL P_Select_Salary ('" + fromdate + "',  '" + todate + "','" + unitId + "', 'Salary_Summary')";
        Class.forName(driver);
        con = DriverManager.getConnection(connection);
        stmt = con.createStatement();
        resultset = stmt.executeQuery(selectstatement);
        JRResultSetDataSource resultsetdatasource = new JRResultSetDataSource(resultset);

        String selectstatement1 = "CALL P_Select_Salary ('2013-01-01', '2013-01-31', 1, 'Salary_OA')";
        Class.forName(driver);
        con = DriverManager.getConnection(connection);
        stmt = con.createStatement();
        resultset1 = stmt.executeQuery(selectstatement1);
        while (resultset1.next()) {
            String shortname = resultset1.getString("alw_short_name");
            logger.info("shortname" + shortname);
            String workamount = resultset1.getString("Work_amt");
            logger.info("workamount" + workamount);
            shortnamelist.add(shortname);
            shortnamelist.add(workamount);
        }
        logger.info("shortnamelist" + shortnamelist.size());
        Map<String, Object> hashmap = new HashMap<String, Object>();
        hashmap.put("list1", shortnamelist);
        String realpath = FacesContext.getCurrentInstance().getExternalContext().getRealPath("common/reports/registerofwages.jasper");
        jasperprint = JasperFillManager.fillReport(realpath, hashmap, resultsetdatasource);
        HttpServletResponse httpservlet = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
        httpservlet.addHeader("Content-disposition", "attachment;filename=wageslip.pdf");

        try {
            JasperExportManager.exportReportToPdfStream(jasperprint, httpservlet.getOutputStream());
        } catch (JRException ex) {
            ex.getMessage();
        } finally {
            FacesContext.getCurrentInstance().responseComplete();
        }
    } catch (net.sf.jasperreports.engine.JRException JRexception) {
        logger.info("JRException Exception" + JRexception.getMessage());
        JsfUtil.addErrorMessage("No Datas between FromDate to ToDate");
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        close(stmt);
        close(resultset);
        close(con);
    }
}

Answer 1

我觉得这个很旧，但是，对于下一个寻找它的人来说......

Jasper Studio和ireport有时会为字段创建空白描述：

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

删除这些，您应该停止收到此错误。

另见：https://community.jaspersoft.com/questions/527187/nosuchmethodexception-unknown-property

Answer 2

Yonatan的答案对我有用!!!，在字段中

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

我像这样更改JPA中的attributo

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

someColumn提供JPA Objecte包含的属性，在设计更改后尝试报告并运行。在java代码中，我构建一个只包含打印对象的List：

List<Producto> toPrint = new Stack<>();
    toPrint.add(selected);
    JRBeanCollectionDataSource  beanCollectionDataSource = new JRBeanCollectionDataSource(toPrint);

为我工作更改JPA对象包含的属性的空字段。

Answer 3

对我来说，只需将false传递给JRBeanCollectionDataSource（isUseFieldDescription）的第二个参数即可解决我的问题。

new JRBeanCollectionDataSource(collection, false);

Answer 4

这适合我。

如果您在报告字段中添加了空格，请删除空格。

像这样添加false。

JRDataSource JRdataSource = new JRBeanCollectionDataSource(/*your data's*/, false);

Answer 5

检查您的吸气剂和吸气剂。命名不当可能会引起我的问题。

java.lang.NoSuchMethodException：类'java.lang.String'上的未知属性''
