在java中读取.xlsx文件

标签： java struts2

我正在尝试上传Excel 2007（.xlsx）文件，然后使用Struts 2使用以下代码读取其数据：

InputStream inp = new FileInputStream(upload);
Workbook wb_xssf;
Sheet sheet = null; 
wb_xssf = new XSSFWorkbook(inp);// ERROR Line 4
sheet = wb_xssf.getSheetAt(0);

然而，它在第4行（如上所示）引发错误。有人可以帮忙解决这个问题吗？

我正在使用以下JAR：

  • dom4j 1.1
  • xmlbean 2.3.0
  • poi 3.9 jars

struts.xml中的文件上传拦截器

<interceptor-ref name="fileUpload">
    <param name="allowedTypes"> 
        application/vnd.ms-excel,application/x-msexcel,application/ms-      excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
    </param>
    <param name="maximumSize">
        1073741824
    </param>
</interceptor-ref>

这是异常的堆栈跟踪：

您的例外的实际（根本原因）就在这一行。

java.lang.ClassNotFoundException: org.dom4j.DocumentException

下载DOM4J并将库放入类路径并编译/构建代码。
