Java 从JasperReports处的bean:name检索字段值时出错

我收到了标题中提到的错误消息。我尝试了我在不同论坛上找到的所有东西，但没有任何效果

这是我的Bean类：

public class NameBean {
    private String reportName, shortDescription, description;

    public NameBean(String reportName, String shortDescription, String description) {
        this.reportName = reportName;
        this.shortDescription = shortDescription;
        this.description = description;
    }

    public String getName(){
        return reportName;
    }

    public String getShortDescription() {
        return shortDescription;
    }

    public String getDescription() {
        return description;
    }

    public void setName(String reportName){
        this.reportName = reportName;
    }

    public void setShortDescription(String shortDescription) {
        this.shortDescription = shortDescription;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}

public  class TestFactory {

    public static ArrayList generateCollection() {
        ArrayList collection = new ArrayList();

        collection.add(new NameBean("PS_TF_VSGM-A-2535_01", "Automatisches Starten der Online-Prüfung und -Aktualisierung", 
                "Der Konfigurationsparameter zur Online-Prüfung und -Aktualisierung(MODE_ONLINE_CHECK) ist auf den Wert First konfiguriert. Es wird eine eGK in das Kartenterminal des Konnektorsimulators gesteckt für die im laufenden Quartalnoch keine Online-Prüfung durchgeführt wurde."));

        collection.add(new EntranceValuesBean("eingeschaltet", "online", "Ohne TLS", "Standard (PTV 1.6.0)", "Mandat > Terminal > Karte"));

        return collection;
    }
}

我完全不知道如何解决这个问题。

问题似乎是由于类入口值bean造成的。

---

检查该类中是否有名为getName的getter方法。

感谢您提供有关类入口值bean的建议。我删除了它，并将代码写入类NameBean。它现在正在工作。

什么是

入口值bean

？你是如何使用这门课的？您应该将传递数据源的代码发布到报表中
