這是我的JSP頁面...上傳EXCEL文件...我需要爲不同的動作uplode 2個不同的excel文件...我希望標籤我是自我解釋...如何使用struts2讀取excel文件應用程序將其轉換爲.tmp
<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>
下一個是這2個動作我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>
下一個是動作類...
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;
}
}
而我輸入我得到這個控制檯...
null
upload__6e26fdaa_137cba00800__8000_00000001.tmp
和近w = Workbook.getWorkbook(uploadToAllocate);拋出的異常是......

我找到了原因，但沒有解決方案。原因是excel不是以正確的方式創建的。它是通過創建一個擴展名爲「.xls」的文件創建的。但看到'MS Excel'可以打開它，爲什麼不用java代碼可以做到這一點？ –
