二话不说上代码

练习：

view:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<title>ff</title>
<link rel="stylesheet" type="text/css" href="ext3.0/resources/css/ext-all.css" />
<script type="text/javascript" src="ext3.0/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="ext3.0/ext-all.js"></script>
<script type="text/javascript" src="ext3.0/FileUploadField.js"></script>
<style type="text/css">
.special-css{
font-size:9pt;color:red;padding:3px;
}
</style>
<script type="text/javascript">
Ext.onReady(function (){
  Ext.QuickTips.init();
  Ext.BLANK_IMAGE_URL="ext3.0/resources/images/default/s.gif";

  var _form=new Ext.form.FormPanel({
   title:'文件上传',

   frame:true,
   border:false,
   height:100,
   fileUpload:true,
   width:400,
   applyTo:'form',
   url:'http://localhost:8080/myst/filefile.action',
   items:[{
   xtype:'textfield',
   allowBlank:false,
   name:'reportFile',
   fieldLabel:'文件上传',
   inputType:'file',
   id:'fl'
   }],
   buttons:[{
    text:'提交',
    handler:function (){
     if(_form.getForm().isValid()){
      _form.getForm().doAction('submit',{
       clientValidation : true,

       success:function (form,action){
        Ext.Msg.alert('信息',"s");
       },
       failure:function (form,action){
        Ext.Msg.alert('错误','失败');
       }
      });
     }

    }
   }]

  });

});
</script>

</head>
<body>

<div id="form"></div>
</body>
</html>

Action:

public class FileForm extends ActionSupport implements ServletRequestAware , ServletResponseAware{
private File file;
private String fileFileName;
private HttpServletRequest request;
private HttpServletResponse response; 

public File getFile() {
 return file;
}

public void setFile(File file) {
 this.file = file;
}

public String getFileFileName() {
 return fileFileName;
}

public void setFileFileName(String fileFileName) {
 this.fileFileName = fileFileName;
}

//读文本文件的。
 public String execute() throws Exception {

  FileInputStream fi = new FileInputStream(this.getFile());

  BufferedReader br = new BufferedReader(new InputStreamReader(fi));
  String line ="";

  while((line= br.readLine())!=null){
   System.out.println(line);
  }
   br.close();

   response.reset();
   PrintWriter writer = response.getWriter();
   writer.write("{success:true}");
  return null;
 }

 @Override
 public void setServletRequest(HttpServletRequest request) {
  this.request=request;

 }

 @Override
 public void setServletResponse(HttpServletResponse response) {
  this.response= response;

 }
/*读Excel文件，也可以将文件里的内容插入到数据库中相应的jar为jxl.jar
public void readExcel(File file) throws Exception{
   try {   
          Workbook book = Workbook.getWorkbook(file);   
          Sheet se = book.getSheet(1);
          int rownum = se.getRows();

          for (int i = 1; i < rownum; i++) {   
             System.out.println(se.getCell(0,i)+","+se.getCell(1,i)+","+se.getCell(2,i));

          }   
          book.close();   

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

      }   
}
*/

s2:

<action name="fileform" class="com.wys.web.FileForm">
</action>

其它略。。
