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;
