在生成 birt 报告期间，我的表现低于预期。下面给出了带有堆栈跟踪的代码。

我需要在我的应用程序中添加任何其他与字体相关的文件吗？有没有人对此有想法。

当我将渲染选项设置为“HTML”时，它工作正常。仅当我将渲染选项设置为“pdf”时才抛出异常。

BirtEngineDesktop.java：导入java.io.File；导入 java.io.FileInputStream；导入 java.util.HashMap；导入 java.util.logging.Level；导入 org.eclipse.birt.core.exception.BirtException；导入 org.eclipse.birt.core.framework.Platform；导入 org.eclipse.birt.report.engine.api.*；

公共类 BirtEngineDesktop {

public static void main(String[] args) throws Exception {
    String reportName = "new_report_2.rptdesign";
    IReportEngine engine = null;
    IReportRunnable design = null;
    IRunAndRenderTask task = null;
    PDFRenderOption renderContext = null;
    HashMap contextMap = null;
    PDFRenderOption options = null;
    final EngineConfig conf = new EngineConfig();
    conf.setEngineHome("ReportEngine");
    System.out.println("BIRT_HOME: " + conf.getBIRTHome());
    conf.setLogConfig(null, Level.FINE);

    try {
        Platform.startup(conf);
    } catch (BirtException e1) {
        e1.printStackTrace();
    }

    IReportEngineFactory factory = (IReportEngineFactory) Platform
            .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
    engine = factory.createReportEngine(conf);

    try {
        design = engine.openReportDesign(reportName); 
    } catch (Exception e) {
        System.err.println("An error occured during the opening of the report file!");
        e.printStackTrace();
        System.exit(-1);
    }
    task = engine.createRunAndRenderTask(design);
    renderContext = new PDFRenderOption();
    contextMap = new HashMap();
    FileInputStream fis = new FileInputStream(new File("C:\\test\\sample.xml"));
    contextMap.put("org.eclipse.datatools.enablement.oda.xml.inputStream",fis);     
    contextMap.put(EngineConstants.APPCONTEXT_PDF_RENDER_CONTEXT,
            renderContext);
    task.setAppContext(contextMap);


    options = new PDFRenderOption();
    options.setOutputFileName("D://"+reportName + ".pdf");         options.setOutputFormat("pdf");
    task.setRenderOption(options);
    try {
        task.run();
    } catch (Exception e) {
        e.printStackTrace();
        System.exit(-1);
    }
   engine.destroy();
    System.exit(0);
} }

我的堆栈跟踪是：

尝试：

  • 将您的字体目录添加到 CLASSPATH（或将报告字体复制/符号链接到 CLASSPATH 中的任何目录）

  • 使用以下代码注册字体目录：

    import java.security.AccessController;
import java.security.PrivilegedAction;    
import com.lowagie.text.FontFactory;

...

AccessController.doPrivileged(new PrivilegedAction<Object>() {
        public Object run() {
                FontFactory.registerDirectory(yourFontsDirectory);
                return null;
        }
});

字体目录应包含报表设计使用的 ttf 字体。

我认为您需要将语言环境设置为task.setLocale(new Locale("en", "US"));
