陷入在 iReport、JasperReports、Struts 2 插件中获取空值的困境

Question

我正在使用 JasperReports 和 Struts2 在我的 Web 应用程序中制作一些报告。

为了设计目的，我使用 NetBeans IDE 和 iReport 3.5.1 插件完成所有这些工作。

我正在通过以下 xml 代码配置我的 struts2-jasperreports 插件。

<package name="jasper1" extends="jasperreports-default,struts-default">
    <result-types>
        <result-type name="jasper" class="org.apache.struts2.views.jasperreports.JasperReportsResult"/>
    </result-types>

    <action name="myJasperTest" class="testJasperAccountAction">

        <result name="success" type="jasper">
            <param name="location">/reports/account.jasper</param>
            <param name="dataSource">accounts</param>
            <param name="format">PDF</param>
        </result>

        <result name="error" type="jasper">/error.jsp</result>

    </action>
</package>

我的动作类如下。

public class JasperAccountAction extends ActionSupport {

    private IAccountSecurityProcessor accountSecurityProcessor;
    private static ArrayList<Account> accounts;

    public void setAccounts(ArrayList<Account> accounts) {
        JasperAccountAction.accounts = accounts;
    }

    @Override
    public String execute() throws Exception {
        return SUCCESS;
    }

    public void setAccountSecurityProcessor(IAccountSecurityProcessor accountSecurityProcessor) {
        this.accountSecurityProcessor = accountSecurityProcessor;
    }

    public ArrayList<Account> getAccounts() throws Exception {
        try {
            accounts = (ArrayList<Account>) this.accountSecurityProcessor.findByAll(0, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, false, false, null, null, null, null, 0);

            JasperCompileManager.compileReportToFile("E:\\Final_copy_of_erp\\SufalamERP\\build\\web\\reports\\account.jrxml", "E:\\Final_copy_of_erp\\SufalamERP\\build\\web\\reports\\account.jasper");
            System.out.println("*******************************Accounts list for japser = =" + accounts + " ****************************************");
        } catch (SufalamException ex) {
            ex.printStackTrace();

            System.out.println("*******************************Exception in sufalam ==>" + ex);
            Logger.getLogger(JasperAccountAction.class.getName()).log(Level.SEVERE, null, ex);
        }
        return accounts;
    }
}

我的贾斯珀报告如下：

Answer 1

看起来您的 JasperReport.xml 只是缺少文档类型。 尝试以这种方式启动文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN" 
 "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
<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="null" pageWidth="595" pageHeight="842" columnWidth="535" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">

Answer 2

字段名称应与帐户 bean 的属性名称相似

Answer 3

我遇到了同样的问题，当然，我只需从我的 bean

中输入正确的字段名称就可以修复它在你的 .jrxml 中；）

我花了几天时间。

顺便把jasper、apache commons*、poi、itext、jxl的所有jar包都放上。
