struts2 不用标签文件上传
发现网上和书上都是带<s:file>的
有没有不带的例子,请分享下,谢谢 struts2
[解决办法]
如果不用s的标签 那就用input type="file" 做上传一样的
[解决办法]
网上很多 上传下载啊。自己搜啊。 什么ajax 上传，基于servlet上传。

不用标签也一样的呀
index.jsp
<body>
<form action="uploadAction.action" method="post" enctype="multipart/form-data">
<input type="file" name="image"><br/>
<input type="submit" value="上传">
</form>
${message}
</body>
public class UploadAction extends ActionSupport {
private File image;
private String imageFileName;
private String imageContentType;
private String filePath;
public String getFilePath() {
return filePath;
}
public void setFilePath(String filePath) {
this.filePath = filePath;
}
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;
}
@Override
public String execute() throws Exception {
System.out.println("upload");
String realpath = ServletActionContext.getServletContext().getRealPath(
"/images");
if (this.image != null) {
File savefile = new File(new File(realpath), imageFileName);
if (!savefile.getParentFile().exists())
savefile.getParentFile().mkdirs();
FileUtils.copyFile(image, savefile);
this.filePath = "images/" + imageFileName;
ActionContext.getContext().put("message", "文件上传成功");
}
return UploadAction.SUCCESS;
}
}
