Jasper 报告组件在 JavaFX Swing 节点中未正确呈现

为了在JavaFX 11中创建Jasper Report,我使用的是动态报告。我正在Swing Node中加载报告,但只有当我将单击堆栈窗格区域并且仅当我将鼠标悬停在所有这些组件上时,Jasper报告才会出现。并且所有其他组件都可见。组件和报表内容不会立即加载,而不是在鼠标悬停时显示,并且在滚动到“堆栈窗格”上时显示报表。

由于这是Java 8中的错误,似乎已经解决,但在Java 11中,我也遇到了同样的问题。

更新

由于我没有得到任何回应,并且正如kleopatra所建议的那样,我已经创建了最小的可重现代码。请对此进行调查。

输出

  1. 单击加载报告按钮后,只有一个保存图标可见,报告不可见。After clicking on load report button only one save icon is visible no report is visible

  2. 单击堆栈窗格区域后,现在报告可见。After clicking on Stack Pane Area now Report is visible

  3. 将鼠标悬停在另一个图标上后,现在可以看到“打印”图标。After hovering over another icon now Print icon is visible

  4. 将鼠标悬停在其他图标上后,它们也会逐个可见。After hovering over other icons as well they are getting visible one by one


答案 1

在检查OpenJDK wiki的OpenJFX调试标志后,您可以尝试遵循。

为 OpenJFX 添加 JVM 选项的构建部分pom.xml

<plugin>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>0.0.4</version>
    <configuration>
        <mainClass>demo.JavaFxJasperReportsDemo</mainClass>
        <options>
            <option>-Dprism.verbose=true</option>
        </options>
    </configuration>
</plugin>

执行应用程序,它将报告检测到的棱镜配置mvn javafx:run

系统上的输出

Prism pipeline init order: es2 sw 
Using Double Precision Marlin Rasterizer
Using dirty region optimizations
Not using texture mask for primitives
Not forcing power of 2 sizes for textures
Using hardware CLAMP_TO_ZERO mode
Opting in for HiDPI pixel scaling
Prism pipeline name = com.sun.prism.es2.ES2Pipeline
Loading ES2 native library ... prism_es2
    succeeded.
GLFactory using com.sun.prism.es2.X11GLFactory
(X) Got class = class com.sun.prism.es2.ES2Pipeline
Initialized prism pipeline: com.sun.prism.es2.ES2Pipeline
...
Graphics Vendor: Intel Open Source Technology Center
       Renderer: Mesa DRI Intel(R) Ivybridge Mobile 
        Version: 3.0 Mesa 19.3.2

它使用硬件加速渲染器Loading ES2 native library ... prism_es2

可以强制使用软件渲染器。更改pom.xml

        <options>
            <option>-Dprism.verbose=true</option>
            <option>-Dprism.order=sw</option
        </options>

然后,输出为

Prism pipeline init order: sw 
Using Double Precision Marlin Rasterizer
Using dirty region optimizations
Not using texture mask for primitives
Not forcing power of 2 sizes for textures
Using hardware CLAMP_TO_ZERO mode
Opting in for HiDPI pixel scaling
*** Fallback to Prism SW pipeline
Prism pipeline name = com.sun.prism.sw.SWPipeline
(X) Got class = class com.sun.prism.sw.SWPipeline
Initialized prism pipeline: com.sun.prism.sw.SWPipeline
 vsync: true vpipe: false

它正在使用软件渲染器。Fallback to Prism SW pipeline

用于上述测试的版本:

答案 2

我也遇到了类似的问题,但我通过将以下maven依赖项添加到我的项目中解决了它。我认为它可以帮助某人。请不要我更喜欢使用JRViewerFX,因为它解决了问题,UI远远好于挥杆。

<dependency>
    <groupId>win.zqxu</groupId>
    <artifactId>jrviewer-fx</artifactId>
    <version>0.1.1</version>

</dependency>

这里是实现它的代码部分

        JRViewerFX viewer = new JRViewerFX(jasperprint_report);        

              Platform.runLater(new Runnable() {
                  @Override
                  public void run() {

                      report_scroll_pane.setContent(viewer);
                  }
              });
