简单写了一个，楼主不明白的问我。
jsp :

	

	<s:form action="doUpload" method="POST" enctype="multipart/form-data">

		<s:file name="upload" label="File"/>

		<s:submit value = "Upload" />

	</s:form>

就写了一些重点的东西
struts-fileupload.xml

<struts>

	<package name="fileupload" extends="struts-default" namespace="/fileupload">

        

        <action name="doUpload" class="actions.fileupload.FileUploadAction" method="execute">

        	

	<result>upload-success.jsp</result>

		</action>

    </package>

</struts>

FileUploadAction.java

public Workbook createWorkBook(InputStream is) throws IOException{    

	       if(fileName.toLowerCase().endsWith("xls")){    

	            return new HSSFWorkbook(is);    

	       }else if(fileName.toLowerCase().endsWith("xlsx")){  

	            return new XSSFWorkbook(is);  

	       }else{  

	            return null;  

	       }  

	    } 

	

	public String execute() throws Exception{

		

		Workbook book = createWorkBook(new FileInputStream(upload));  

        if(null !=book){

        	if (book.getNumberOfSheets()> 0){
