為什么JasperViewer（基於SWing的組件）在JavaFX項目中不支付報告？

[英]Why JasperViewer (Swing based component) is not dispaying report at JavaFX project?

 原文  2018-08-03 22:57:46  0   1    java/ swing/ javafx/ jasper-reports

問題描述

我有2個運行JasperReports的項目。 一種運行在JavaFX上，另一種運行在純Java和主類上。 現在，如果我運行普通的Java項目，jasperReport可以工作並顯示（通過JasperViewer類），但是對於JavaFX項目，它可以工作，但是單擊按鈕后沒有報告顯示。

為什么它不能用於普通Java類，卻不能用於JavaFX？
我該怎么做才能使其在JavaFX中工作？

除了JavaFx和純Java，其他所有內容都是相同的。 我為此下載了以下jar文件：

  • 動態Jasper 5.0.5。 罐
  • jasperreports 5.6.0.jar
  • commons-logging 1.2.jar
  • 公地beanutils 1.9.2.jar

  • 共用消化池2.1.jar

    公地收藏3.2.2.jar

以下是項目：

NO.1。 JavaFX的：

DynaReportApp.java類

    public DynaReportApp() {

        list.add(new Employee(101, "Ravinder Shah",  67000, (float) 2.5));
        list.add(new Employee(102, "John Smith",  921436, (float) 9.5));
        list.add(new Employee(103, "Kenneth Johnson",  73545, (float) 1.5));
        list.add(new Employee(104, "John Travolta",  43988, (float) 0.5));
        list.add(new Employee(105, "Peter Parker",  93877, (float) 3.5));
        list.add(new Employee(106, "Leonhard Euler",  72000, (float) 2.3));

好吧，這真是過山車，但是我終於找到了解決方案，希望它對其他人也有幫助。 因此，顯然上述方法是正確的。 一切都是正確的。 唯一缺少的是jasper-compliler-jdlt 5.5.23.jar 。 因此，只要您具有上述所有罐子，它都應該起作用。 我還注意到，由於某種原因，如果您使用更高的DynamicJasper版本（如5.1.1），則整個操作將無法正常進行。 因此，只需嘗試保留以下jar文件（完整的jar文件列表可在下面找到）以及上述實現，就可以了。 歡呼和快樂的編碼:)

jar文件列表 

DynamicJasper 5.0.5. jar
commons-beanutils 1.9.2.jar
commons-collections 3.2.2.jar
commons-digester 2.1.jar
commons-logging 1.2.jar
jasperreports 5.6.0.jar or jasperreports 6.0.0.ar
jasper-compliler-jdlt 5.5.23.jar
