FtpUtils 工具类封装
public static boolean uploadFile(String hostname, int port, String username, String password, String pathname, String remote,InputStream local) { boolean flag=false;try{ //创建 FtpClient 对象 FTPClient client=new FTPClient(); //建立和 ftp服务器的链接 client.connect(hostname, port); //登陆 ftp服务器 client.login(username, password); //设置上传的文件的类型 client.setFileType(FTP.BINARY_FILE_TYPE); //切换工作目录，文件上传后保存到那个目录 if(!client.changeWorkingDirectory(pathname)){ if(client.makeDirectory(pathname)){client.changeWorkingDirectory(pathname); } }local=new FileInputStream("D:/pic/1.jpg"); //实现文件上传 client.storeFile(remote, local); local.close(); client.logout(); client.disconnect(); flag=true;}catch(Exception ex){ ex.printStackTrace(); } return flag; }
通过 Http 访问图片
Ego 上传商品图片
前端控件参数说明
提交上传请求路径 url
提交图片参数名称
上传后返回值 json模型
参考 kindeditor 控件文件上传文档:
KindEditor 4.x Documentation
2.2 创建 PictureResult 封装返回值
package com.bjsxt.ego.beans;/*** * 封装上传图片之后的返回结果 * **/ public class PictureResult { private Integer error; //状态 1 失败 0 成功 private String url; //上传图片后，图片在服务器的 url private String message;//响应到客户端的提示消息 public Integer getError() { return error; } public void setError(Integer error) { this.error = error; } public String getUrl() { return url; } public void setUrl(String url) {this.url = url;} public String getMessage() { return message; } public void setMessage(String message) { this.message = message; }}
ego-manager-web 功能实现
创建 ftp.properties
FTP_HOST=192.168.30.30FTP_PORT=21 FTP_USERNAME=ftpuser FTP_PASSWORD=ftpuser FTP_PATH=/home/ftpuser/jd IMAGE_HTTP_PATH=/jd
创建工具类 IDUtils
ManagerItemService 接口添加方法
public PictureResult uploadItemPic(MultipartFile file);
ManagerItemServiceImpl 实现方法
//通过 spring 的 EL表达式注入 ftp信息 @Value("${FTP_HOST}") private String FTP_HOST; @Value("${FTP_PORT}") private Integer FTP_PORT; @Value("${FTP_USERNAME}") private String FTP_USERNAME; @Value("${FTP_PASSWORD}") private String FTP_PASSWORD; @Value("${FTP_PATH}") private String FTP_PATH; @Value("${IMAGE_HTTP_PATH}") private String IMAGE_HTTP_PATH; @Override public PictureResult uploadItemPic(MultipartFile file) { // TODO Auto-generated method stub boolean flag=false; String fileName=null; try{ //获得信息的文件名字 fileName=IDUtils.genImageName(); //获得上传的文件的原始名字 String oriName = file.getOriginalFilename(); //获得文件扩展名 String ext=oriName.substring(oriName.lastIndexOf(".")); fileName=fileName+ext;InputStream local = file.getInputStream(); //实现文件上传到ftp flag=FtpUtils.uploadFile(FTP_HOST, FTP_PORT, FTP_USERNAME, FTP_PASSWORD, FTP_PATH, fileName, local); }catch(Exception ex){ ex.printStackTrace(); flag=false; }PictureResult result=null; if(flag){ result=new PictureResult();result.setError(0); result.setUrl(IMAGE_HTTP_PATH+"/"+fileName); result.setMessage("ok"); }else{ result=new PictureResult(); result.setError(1); result.setUrl("url"); result.setMessage("error"); } return result; }
创建 ItemImageUploadController类
package com.bjsxt.ego.manager.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.MediaType; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.multipart.MultipartFile; import com.bjsxt.ego.beans.PictureResult; import com.bjsxt.ego.manager.service.ManagerItemService; @Controller public class ItemImageController { //注入service @Autowired private ManagerItemService managerItemService; /** * 处理图片上传请求 * ***/ @RequestMapping(value="pic/upload",produces=MediaType. APPLICATION_JSON_VAL UE +";charset=UTF-8") @ResponseBody public PictureResult picUpload(MultipartFile uploadFile){ return managerItemService.uploadItemPic(uploadFile); }}
配置 springmvc.xml
