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;
    
    /**

     */
    @Controller
    public 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   99
    		for(int i=0 ; i<3 ;i++){
    			format += r.nextInt(10);
    		}
    		
    		//实例化一个Jersey
    		Client 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   PUT
    		try {
    			resource.put(String.class, pic.getBytes());
    		} catch (IOException e) {
    			// TODO Auto-generated catch block
    			e.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Map
    		Set<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   99
    			for(int i=0 ; i<3 ;i++){
    				format += r.nextInt(10);
    			}
    			
    			//实例化一个Jersey
    			Client 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   PUT
    			try {
    				resource.put(String.class, pic.getBytes());
    			} catch (IOException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
    			//返回Url给Fck   fck-core...jar   ckeditor
    			UploadResponse 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 block
    				e.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 block
    			e.printStackTrace();
    		}
    	}
    	//发送的是JSON
    	public static void renderJson(HttpServletResponse response,String text){
    		render(response, "application/json;charset=UTF-8", text);
    	}
    	//发送xml
    	public static void renderXml(HttpServletResponse response,String text){
    		render(response, "text/xml;charset=UTF-8", text);
    	}
    	//发送text
    	public static void renderText(HttpServletResponse response,String text){
    		render(response, "text/plain;charset=UTF-8", text);
    	}
    	
    	
    }

三.jsp使用

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@ include file="/WEB-INF/back_page/head.jsp" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <title>babasport-add</title>
    <script type="text/javascript">
    
    function uploadPic(){
    	//alert(1);
    	//定义参数
    	var options = {
    		url : "/upload/uploadPic.do?",
    		dataType : "json",
    		type :  "post", 
    		success : function(data){
    			//回调 二个路径  
    			//url
    			//path
    			alert(3);
    			$("#allImgUrl").attr("src",data.url);
    			$("#path").val(data.path);
    		}
    	};
    	//jquery.form使用方式
    	$("#jvForm").ajaxSubmit(options);
    	
    }
    </script>
    </head>
    <body>
    <div class="box-positon">
    	<div class="rpos">当前位置: 部门管理 - 添加</div>
    	<form class="ropt">

    <div class="body-box" style="float:right">

    		<table cellspacing="1" cellpadding="2" width="100%" border="0" class="pn-ftable">
    			<tbody>
    				<tr>
    					<td width="20%" class="pn-flabel pn-flabel-h">

    						</form:select>
    						<span class="pn-frequired"><form:errors path="companyName"></form:errors></span>
    						<span class="pn-frequired">${cpInfo }</span>
    						
    					</td>
    				</tr>
    				<tr>
    					<td width="20%" class="pn-flabel pn-flabel-h">
    						部门名:</td><td width="80%" class="pn-fcontent">

    					</td>
    				</tr>
    			</tbody>
    			<tbody>
    				<tr>
    					<td class="pn-fbutton" colspan="2">
    						<input type="submit" class="submit" value="提交"/>   <input type="reset" class="reset" value="重置"/>
    					</td>
    				</tr>
    			</tbody>
    		</table>
    		</form:form>
    </div>
    </body>
    </html>
