struts2单文件上传案例演示(一)

public class UploadAction1 extends ActionSupport implements Serializable { private File image;//对应的就是表单中文件上传的那个输入域的名称，Struts2框架会封装成File类型的 private String imageFileName;//   上传输入域FileName  文件名 private String imageContentType;// 上传文件的MIME类型 public File getImage() { return image; }


public void setImage(File image) { this.image = image; }


public String getImageFileName() { return imageFileName; }


public void setImageFileName(String imageFileName) { this.imageFileName = imageFileName; }


public String getImageContentType() { return imageContentType; }


public void setImageContentType(String imageContentType) { this.imageContentType = imageContentType; }


public String execute(){ System.out.println(imageContentType); try { //处理实际的上传代码 //找到存储文件的真实路径// System.out.println(imageFileName); ServletContext sc = ServletActionContext.getServletContext(); String storePath = sc.getRealPath("/files"); //构建输入输出流// OutputStream out = new FileOutputStream(storePath+"\\"+imageFileName);// InputStream in = new FileInputStream(image);// byte b[] = new byte[1024];// int len = -1;// while((len=in.read(b))!=-1){// out.write(b, 0, len);// }// out.close();// in.close(); FileUtils.copyFile(image, new File(storePath,imageFileName)); ActionContext.getContext().put("message", "上传成功！"); return SUCCESS; } catch (Exception e) { e.printStackTrace(); return ERROR; } }}
