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;

}

}
