通过 apache POI 读取 java 中的 .xlsx
Reading .xlsx in java through apache POI
我正在尝试将 .xlsx 文件中的数据读入我的 java 程序。我能够阅读 .xls 但当我尝试使用 .xlsx 的相同代码时出现异常。
访问文件的代码：
FileInputStream fs = new FileInputStream(inputFile);
Workbook wb = WorkbookFactory.create(fs);
Sheet sheet = wb.getSheetAt(0);
异常跟踪：

我已经尝试将 XMLbeans.jar 更新到最新版本，但我仍然得到这个。
我认为您必须使用 XSSFWorkbook 而不是 Workbook read read detail example at http://java67.blogspot.in/2014/09/how-to-read-write-xlsx-file-in-java-apache-poi-example.html
FileInputStream fs = new FileInputStream(inputFile);
//Workbook wb = WorkbookFactory.create(fs);
XSSFWorkbook wb = new XSSFWorkbook(fs);
XSSFSheet sheet = wb.getSheetAt(0);
如果使用 maven:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.9</version>
</dependency>
或者我使用的罐子：
commons-codec-1.9.jar
commons-logging-1.1.3.jar
junit-4.12.jar
log4j-1.2.17.jar
poi-3.13-20150929.jar
poi-examples-3.13-20150929.jar
poi-excelant-3.13-20150929.jar
poi-ooxml-3.13-20150929.jar
poi-ooxml-schemas-3.13-20150929.jar
poi-scratchpad-3.13-20150929.jar
xmlbeans-2.6.0.jar
如果还是报错，请新建一个xlsx文件进行测试
您的异常的关键部分接近尾声：
Caused by: org.apache.xmlbeans.SchemaTypeLoaderException: XML-BEANS compiled schema:
Incompatible minor version - expecting up to 23, got 24 (schemaorg_apache_xmlbeans.system.sE130CAA0A01A7CDE5A2B4FEB8B311707.index) - code 3
这表明您使用的 XMLBeans 版本比编译模式 jar 的版本旧。您可以将较旧的模式与较新的运行时一起使用，但反之则不行
截至 2015 年 11 月，Apache POI 使用 Apache XMLBeans 2.3 构建架构 jar，并将 2.6 作为默认运行时发布。这意味着您需要在运行时使用 2.3 或更高版本
根据异常情况，您似乎正在使用 XMLBeans 2.2。删除/替换旧的 XMLBeans jar，所以你有 2.3 或更新版本（最好是最新的 2.6），一切都会开始工作
另请注意，仅将更新的 XMLBeans jar 添加到您的类路径是不够的 - 您还需要删除旧的。如果类路径上有旧的和新的，旧的通常会获胜！
