我在Tomcat中运行，jasper报告与PDF崩溃，excel仍然运行良好。
JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
ByteArrayOutputStream os = new ByteArrayOutputStream();
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(os));
exporter.exportReport();
错误已解决：
java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V
net.sf.jasperreports.engine.export.JRPdfExporter.exportReportToStream(JRPdfExporter.java:480)

javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
我使用以下库： -iText-2.1.7.js2.jar -itext-4.2.0.jar -itextpdf-5.5.0.jar -jasperreports-5.6.0.jar -jasperreports-fonts-5.6.0.jar -jasperreports-javaflow-5.6.0.jar
感谢您的帮助！

与jasperreports版本相比，您的itext版本较旧。请使用最新版本。请注意，artifactId和/或groupId已更改：-
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.13</version>
</dependency>

使用最新版本5.5.13后，我检查了构建文件后的war文件是否具有text-2.0.8版本并引起了错误。那么如何解决？
这是build.grade文件：
