Jersey上传服务器---使用

一.Controller

package cn.itcast.core.controller.admin;import java.io.IOException;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.Date;import java.util.Map;import java.util.Map.Entry;import java.util.Random;import java.util.Set;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import net.fckeditor.response.UploadResponse;import org.apache.commons.io.FilenameUtils;import org.json.JSONObject;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.multipart.MultipartFile;import org.springframework.web.multipart.MultipartHttpServletRequest;import cn.itcast.common.web.ResponseUtils;import cn.itcast.core.web.Constants;import com.sun.jersey.api.client.Client;import com.sun.jersey.api.client.WebResource;/** * 上传图片 * 商品 * 品牌 * 商品介绍Fck * Title: UploadController.java * Description: * @author xwp * @date 2017年5月3日下午9:34:12 * @version 1.0 */@Controllerpublic class UploadController {//上传图片@RequestMapping(value = "/upload/uploadPic.do")public void uploadPic(@RequestParam(required = false) MultipartFile pic,HttpServletResponse response){//扩展名String ext = FilenameUtils.getExtension(pic.getOriginalFilename());//图片名称生成策略DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");//图片名称一部分String format = df.format(new Date());//随机三位数Random r = new Random();// n 1000   0-999   99for(int i=0 ; i<3 ;i++){format += r.nextInt(10);}//实例化一个JerseyClient client = new Client();//保存数据库String path = "upload/" + format + "." + ext;//另一台服务器的请求路径是?String url = Constants.IMAGE_URL  + path;//设置请求路径WebResource resource = client.resource(url);//发送开始  POST  GET   PUTtry {resource.put(String.class, pic.getBytes());} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}//返回二个路径JSONObject jo = new JSONObject();jo.put("url", url);jo.put("path",path);ResponseUtils.renderJson(response, jo.toString());}//上传Fck图片@RequestMapping(value = "/upload/uploadFck.do")public void uploadFck(HttpServletRequest request,HttpServletResponse response){//强转request  支持多个MultipartHttpServletRequest mr= (MultipartHttpServletRequest)request;//获取值  支持多个   Map<String, MultipartFile> fileMap = mr.getFileMap();//遍历MapSet<Entry<String, MultipartFile>> entrySet = fileMap.entrySet();for(Entry<String, MultipartFile> entry : entrySet){//上传上来的图片MultipartFile pic = entry.getValue();//扩展名String ext = FilenameUtils.getExtension(pic.getOriginalFilename());//图片名称生成策略DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");//图片名称一部分String format = df.format(new Date());//随机三位数Random r = new Random();// n 1000   0-999   99for(int i=0 ; i<3 ;i++){format += r.nextInt(10);}//实例化一个JerseyClient client = new Client();//保存数据库String path = "upload/" + format + "." + ext;//另一台服务器的请求路径是?String url = Constants.IMAGE_URL  + path;//设置请求路径WebResource resource = client.resource(url);//发送开始  POST  GET   PUTtry {resource.put(String.class, pic.getBytes());} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}//返回Url给Fck   fck-core...jar   ckeditorUploadResponse ok = UploadResponse.getOK(url);//response 返回对象 //response  write //response  print//区别://字符流//字节流try {response.getWriter().print(ok);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}

二.ResponseUtils

package cn.itcast.common.web;import java.io.IOException;import javax.servlet.http.HttpServletResponse;/** * 异步返回各种格式 * Title: ResponseUtils.java * Description: * @author xwp * @date 2017年5月3日下午9:35:06 * @version 1.0 */public class ResponseUtils {//发送内容  public static void render(HttpServletResponse response,String contentType,String text){response.setContentType(contentType);try {response.getWriter().write(text);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}//发送的是JSONpublic static void renderJson(HttpServletResponse response,String text){render(response, "application/json;charset=UTF-8", text);}//发送xmlpublic static void renderXml(HttpServletResponse response,String text){render(response, "text/xml;charset=UTF-8", text);}//发送textpublic static void renderText(HttpServletResponse response,String text){render(response, "text/plain;charset=UTF-8", text);}}

三.jsp使用
