Struts2 在iReport、JasperReports和Struts 2插件中获取空值时遇到了麻烦

我正在使用JasperReports和Struts2在我的web应用程序中生成一些报告

我正在使用NetBeans IDE和iReport 3.5.1插件进行所有这些设计

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

/reports/account.jasper 账户 PDF /error.jsp 我的动作课如下

公共类JasperAccountation扩展了ActionSupport{ 专用IAccountSecurityProcessor accountSecurityProcessor； 私有静态ArrayList帐户； 公共作废集合帐户RAYLIST帐户{ jasperaccountation.accounts=账户； } @凌驾 公共字符串执行引发异常{ 回归成功； } public void setAccountSecurityProcessor accountSecurityProcessor accountSecurityProcessor{ this.accountSecurityProcessor=accountSecurityProcessor； } 公共ArrayList getAccounts引发异常{ 试一试{ accounts=ArrayList this.accountSecurityProcessor.findByAll0，null，null，null，null，null，null，null，null，null，null，null，null，null，null，null，null，false，false，null，0； jaspecompilemanager.compileReportToFileE:\\Final\u copy\u of_erp\\SufalamERP\\build\\web\\reports\\account.jrxml，E:\\Final\u copy\u of_erp\\SufalamERP\\build\\web\\reports\\account.jasper； japser的System.out.println*******************************帐户列表==+帐户+********************************************； }捕获异常{ 例如，打印跟踪； sufalam中的System.out.println******************************异常==>+ex； Logger.getLoggerJasperAccountAction.class.getName.logLevel.SEVERE，null，ex； } 归还账户； } } 我的jasper报告如下：

看起来您的JasperReport.xml只是缺少一个doctype。尝试以下方式启动文件：

<?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">

字段名应该类似于帐户bean的属性名

我遇到了同样的问题，只要从我的bean中输入正确的字段名，我就可以解决这个问题

，当然是在.jrxml中

我在上面呆了几天

顺便说一下，把jasper、ApacheCommons*、poi、itext、jxl的所有jar都放进去。

你能把错误贴出来吗？我猜您的NPE发生在this.accountSecurityProcessor.findByAll。。。这表明依赖项注入失败了，你应该看看你的配置来解决它。嗨，Rich Kroll，我更新了我的问题，有更多的细节，看看它，谢谢你Adynu，但还有一件事你没有注意到，字段名应该与属性名相同。我终于解决了。
