这是我的 JSP 页面...上传 EXCEL 文件...我需要上传 2 个不同的 excel 文件以执行不同的操作...我希望我的标签是不言自明的...

<body>
<s:actionerror />
<s:fielderror />
<s:form action="Admin" method="post" enctype="multipart/form-data" theme="simple">
<big>Import Batch and Tan Details</big>
<br>
<s:file name="uploadToBatch" label="Select a Excel File for Batch import" />
<s:submit action="ImportBatchAndTanDetailsAdmin" value="Import" />
<br>
<big>Allocate Batch</big>
<br>
<s:file name="uploadToAllocate" label="Select a Excel File for Allocation" />
<s:submit action="AllocateAdmin" value="Allocate" onclick=""/>
</s:form>
</body>

接下来是我对这两个动作的 strut.xml 配置...

<action name="*Admin" method="{1}" class="controller.AdminAction">
            <interceptor-ref name="fileUpload">
                <param name="maximumSize">2572864</param>
                <param name="allowedTypes">application/ms-excel,application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet</param>
            </interceptor-ref> 
            <interceptor-ref name="defaultStack"></interceptor-ref>
            <result name="error">adminPage.jsp</result>
            <result name="input">adminPage.jsp</result>
            <result name="success">adminPage.jsp</result>
        </action>

接下来是动作课……

package controller;

import java.io.File;
import jxl.Sheet;
import jxl.Workbook;
import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class AdminAction extends ActionSupport {

    private File uploadToBatch;//The actual file
    private File uploadToAllocate;
    private String uploadContentType; //The content type of the file
    private String uploadFileName; //The uploaded file name
    AuthorIndexingDAO DAO = new AuthorIndexingDAO();

    //getters and setters... 
    public File getUploadToBatch() {
        return uploadToBatch;
    }
    public void setUploadToBatch(File uploadToBatch) {
        this.uploadToBatch = uploadToBatch;
    }
    public File getUploadToAllocate() {
        return uploadToAllocate;
    }
    public void setUploadToAllocate(File uploadToAllocate) {
        this.uploadToAllocate = uploadToAllocate;
    }
    public String getUploadContentType() {
        return uploadContentType;
    }
    public void setUploadContentType(String uploadContentType) {
        this.uploadContentType = uploadContentType;
    }
    public String getUploadFileName() {
        return uploadFileName;
    }
    public void setUploadFileName(String uploadFileName) {
        this.uploadFileName = uploadFileName;
    }



     //ececute method...


    public String execute (){
         return SUCCESS;
     }


     //other methods....
     public String ImportBatchAndTanDetails(){

         try {

                Workbook w;

                    w = Workbook.getWorkbook(uploadToBatch);
                    Sheet sheet = w.getSheet(0);
                    System.out.println(sheet.getName());


                    } catch (Exception e) {
                            e.printStackTrace();
                            System.out.println(e.getMessage());
                            addActionError(e.getMessage());

                    return ERROR;

                    }

         return SUCCESS;
     }


public String Allocate(){

         try {

             System.out.println(uploadFileName);
             System.out.println(uploadToAllocate.getName());

                Workbook w;

                    w = Workbook.getWorkbook(uploadToAllocate);
                    Sheet sheet = w.getSheet(0);
                    System.out.println(sheet.getName());


                    } catch (Exception e) {
                        e.printStackTrace();
                     return ERROR;

                    }

         return SUCCESS;
     }

}

当我导入时，我在控制台中得到了这个......

null
upload__6e26fdaa_137cba00800__8000_00000001.tmp

附近抛出的异常w = Workbook.getWorkbook(uploadToAllocate);是......

我找到了原因。我导入的 excel 没有以正确的方式创建，当我复制内容并将其粘贴到新的 excel 中并保存时，似乎是这样。后来当我导入这个新的excel时它工作正常。

您使用过 jxl api，jxl 仅支持 .xls 扩展名和更旧的扩展名，它不支持更新的扩展名，例如 .xlsx 您应该使用不兼容的扩展名很可能是 .xlsx 这就是为什么
'jxl.read.biff.BiffException: Unable to identify抛出 OLE 流 ' 异常。只需尝试使用扩展名为 .xls 的文件，或者不使用 jxl api 使用 poi。
