阅读Java中的.xlsx文件

我想上传一个Excel 2007（.xlsx）文件，然后阅读使用Struts 2的数据使用下面的代码：阅读Java中的.xlsx文件

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，它的投掷线错误4（如上所示）。任何人都可以帮助解决这个问题吗？

我使用以下JAR：

的dom4j 1.1
的XMLBean 2.3.0
POI 3.9罐子

拦截器进行文件上传在struts.xml中

<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>

这是堆栈跟踪为例外：你的异常的

尝试使用'WorkbookFactory.create（）'而不是对类进行硬编码。 – 2013-03-07 12:46:03

我试过这个，但在WorkbookFactory.create（）方法的例外... – user1584795 2013-03-07 17:35:35

实际（根源）是在这条线。

java.lang.ClassNotFoundException: org.dom4j.DocumentException

下载DOM4J并将库放入类路径并编译/构建您的代码。

我正在使用dom4j1.1.jar – user1584795 2013-03-07 17:36:51

终于我解决了problem.problem是在jar依赖项。我改变了DOM4J1.1到DOM4j 1.6。 – user1584795 2013-03-08 05:19:00
