我有一个应用程序可以读取 .xlsx 文件并向用户显示内容。该应用程序在 Windows 环境中运行良好。
我在 ubuntu 服务器上的 tomcat6 上部署了此 Web 应用程序的 .war 文件。我还复制了服务器上的 .xlsx 文件。
代码中文件路径正确。
但是行
FileInputStream file = new FileInputStream(new File(FileName));
XSSFWorkbook workbook = new XSSFWorkbook(file);
报错
java.lang.reflect.InvocationTargetException
org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException
org.apache.poi.xssf.usermodel.XSSFFactory.createDocumentPart(XSSFFactory.java:62)
org.apache.poi.POIXMLDocumentPart.read(POIXMLDocumentPart.java:403)
org.apache.poi.POIXMLDocument.load(POIXMLDocument.java:155)
org.apache.poi.xssf.usermodel.XSSFWorkbook.<init>(XSSFWorkbook.java:207)
com.qm.action.GetProjectNames.execute(GetProjectNames.java:107)
我已检查变量 FileName 是否包含服务器上文件的正确路径和文件名(/usr/local/Metrics/MetricFiles/FY2013_Q2_GIT_Review_Metrics_by_LSS-GC.xlsx)
由于 ubunut 服务器是虚拟机，我使用 WinSCP 复制了 .xlsx 文件。文件的大小也是正确的。
为什么在linux平台会出现这个错误？
添加额外的异常跟踪

堆栈跟踪的关键部分，它解释了损坏的内容和原因，是:
Caused by: java.lang.OutOfMemoryError: Java heap space at
java.util.Arrays.copyOfRange(Arrays.java:2694)
这告诉我们，Java 没有分配足够的内存来存储处理文件所需的所有数据
如果您在增加 JVM 堆大小方面需要帮助，我建议您查看 this previous question或 this one ，它们都会告诉您所有的一切。
关于java - 使用 apache poi 读取 .xlsx 文件在 linux 机器上给出 org.apache.poi.POIXMLException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16688878/
