• struts多文件上传案例演示(一)


    form表单代码:  
    <form action="${pageContext.request.contextPath }/UpfileAction.do" method="post" enctype="multipart/form-data">
      上传用户:<input type="text" name="username"><br/>
      上传文件:<input type="file" name="list[0]"><br/>
      上传文件:<input type="file" name="list[1]"><br/>
      <input type="submit" value="上传文件">
      </form>

    处理代码:
    public class UpfileForm extends ActionForm {
    private String username;
    private List list = new ArrayList();
    public String getUsername() {
    return username;
    }
    public void setUsername(String username) {
    this.username = username;
    }
    public FormFile getList(int index) {
    return (FormFile) list.get(index);
    }
    public void setList(int index, FormFile file) {
    this.list.add(file);
    }
    public List getAll(){
    return list;
    }
    }

    public class UpfileAction extends Action {

    @Override
    public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response)
    throws Exception {
    UpfileForm upfile = (UpfileForm) form;
    System.out.println(upfile.getUsername());
    List<FormFile> list = upfile.getAll();
    for(FormFile file : list){
    FileOutputStream out = new FileOutputStream("c:\" + file.getFileName());
    InputStream in = file.getInputStream();
    int len = 0;
    byte buffer[] = new byte[1024];
    while((len=in.read(buffer))>0){
    out.write(buffer, 0, len);
    }
    }
    return super.execute(mapping, form, request, response);
    }
    }
