ExtJs文件上传(文本、Excel文件解析)

二话不说上代码

练习：

view:



















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();   

      }   
}
*/
