restlet上传图片代码

客户端用的是 jquery file upload, 服务器端用的是restlet

package org.soachina.rest.component.resource;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;

import org.restlet.resource.Post;
import org.restlet.resource.ServerResource; public class PostDemoResource extends ServerResource {
@Post
public Representation post(Representation entity) {
// getResponse().setStatus(Status.SUCCESS_OK);
// return new StringRepresentation("11111111111" + parameters);
Representation rep = null;
// 1/ Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();
//System.out.println("大头");
// 2/ Create a new file upload handler based on the Restlet
// FileUpload extension that will parse Restlet requests and
// generates FileItems.
RestletFileUpload upload = new RestletFileUpload(factory); // 3/ Request is parsed by the handler which generates a
// list of FileItems
List<FileItem> items = null;
try {
items = upload.parseRepresentation(entity);
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} String filename = ""; for (FileItem fi : items) {
filename = fi.getName();
System.out.println("Save image ... " + filename);
/*新建一个图片文件*/
String extName=filename.substring(filename.lastIndexOf("."));
String newName=new SimpleDateFormat("yyyyMMDDHHmmssms").format(new Date());
File file=new File(newName+extName);
if(!file.exists()){//判断文件是否存在
try {
file.createNewFile(); //创建文件 } catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/*获取文件路径*/
String path_=file.getPath();
/*获取绝对路径名*/
String absPath=file.getAbsolutePath();
/*获取父亲文件路径*/
String parent=file.getParent();
try {
fi.write(file);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }
return null;
}
}
