java.lang.NoSuchMethodError:org.apache.poi.hssf.usermodel.HSSFWorkbook.createDataFormat()Lorg/apache/poi/hssf/usermodel/HSSFDataFormat;

Question

我有一些麻烦将我的报告导出为XLS.PDF格式的导出效果很好.

所以我尝试更新到最新的JasperReports和Apache POI版本:

• JasperReports:5.5.0
• POI:3.7
• iText:2.1.7

但我总是收到以下异常:

java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFWorkbook.createDataFormat()Lorg/apache/poi/hssf/usermodel/HSSFDataFormat;
    net.sf.jasperreports.engine.export.JRXlsExporter.openWorkbook(JRXlsExporter.java:284)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:643)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:723)

出口代码

File sourceFile = new File(fileIn);

JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(sourceFile);

String name = fileIn.substring(fileIn.lastIndexOf(System.getProperty("file.separator"))+1);
name = name.substring(0, name.lastIndexOf("."));
File destFile = new File(fileOut);

JRXlsExporter exporter = new JRXlsExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFile.toString());       
exporter.exportReport();

经过一些研究后,我尝试了其他几个版本(+4),但我仍然收到此错误.有谁知道解决方案？

Answer 1

您的类路径中有一个旧版本库。

如果 jasper 报告依赖于 lib-xxx.jar，请确保类路径中没有其他 lib-yyy.jar。您可以通过查看 jasper 下载的 jar 或 pom.xm 来完成此操作。

我可以猜测你的类路径中有一些旧版本的 poi 。
