Sturts 2 上传excel 获取文件、文件名总是为空 页面和Action name 是一样的

[闪电孩]

页面：

      <div>  
			<form name="uploadForm" enctype="multipart/form-data" action="excel_in.action" >     
			    Excel文件路径:    
			    <input type="file" id="uploadFile" name="upload"><br>   
			    <input class="submit" type="button" onclick="javascript:importEmp();" value="导入">  
			</form>  
		</div>

Action 代码：

public class ExcelInAction {

	private File upload ; //上传的文件  
      
	private String uploadFileName; //保存原始文件名    
    
	private String tip;
	
    public Workbook createWorkBook(InputStream is) throws IOException{    
        if(uploadFileName.toLowerCase().endsWith("xls")){    
            return new HSSFWorkbook(is);    
        }else if(uploadFileName.toLowerCase().endsWith("xlsx")){  
            return new XSSFWorkbook(is);  
        }else{  
            return null;  
        }  
    } 
	
    public String execute() throws Exception{  
 
        Workbook book = createWorkBook(new FileInputStream(upload));  
        if(book == null){//防止跳过页面直接访问报错  
            tip = "请选择excel格式文件";  
            return "success";  
        }  
        Sheet sheet = book.getSheetAt(book.getActiveSheetIndex());

Struts.xml 配置：

		  <!--excel in导入 -->
		 <action name="excel_in" class="com.menu.action.ExcelInAction">
            <result name="success" >/PTUI/lxrglf/excel_in.jsp</result>
		 </action>

 enctype="multipart/form-data" method="post"    


<form  enctype="multipart/form-data" method="post" />   form 标签必须有这个修饰
