JAVA 后台图片的SpringMvc上传与富文本上传ftp服务器功能使用
FTP的配置文件：
ftp.server.ip=192.168.0.227
ftp.user=pengliang
ftp.pass=pengliang
ftp.server.http.prefix=http://img.happymmall.com/SpringMvc的xml的文件的上传配置：

文件上传接口
import org.springframework.web.multipart.MultipartFile;
/**
* Created by geely
*/
public interface IFileService {
String upload(MultipartFile file, String path);
}
文件上传实现类
import com.google.common.collect.Lists;
import com.mmall.service.IFileService;
import com.mmall.util.FTPUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
import java.util.UUID;
/**
* 图片上传的实现
*/
@Service("iFileService")
public class FileServiceImpl implements IFileService {
private Logger logger = LoggerFactory.getLogger(FileServiceImpl.class);
public String upload(MultipartFile file,String path){
String fileName = file.getOriginalFilename();
//扩展名
//abc.jpg
String fileExtensionName = fileName.substring(fileName.lastIndexOf(".")+1);//拿到后缀名不带点
String uploadFileName = UUID.randomUUID().toString()+"."+fileExtensionName; //生成不同的名字
logger.info("开始上传文件,上传文件的文件名:{},上传的路径:{},新文件名:{}",fileName,path,uploadFileName);
File fileDir = new File(path); //创建文件夹
if(!fileDir.exists()){
fileDir.setWritable(true);
fileDir.mkdirs();
}
File targetFile = new File(path,uploadFileName);
try {
file.transferTo(targetFile);
//文件已经上传成功了
FTPUtil.uploadFile(Lists.newArrayList(targetFile));
//已经上传到ftp服务器上
targetFile.delete();
} catch (IOException e) {
logger.error("上传文件异常",e);
return null;
}
//A:abc.jpg
//B:abc.jpg
return targetFile.getName();
}
}文件上传方法的使用（Controller）
@RequestMapping("upload.do")
@ResponseBody
//红色部分是方法返回值类型
public ServerResponse upload(HttpSession session, @RequestParam(value = "upload_file", required = false) MultipartFile file, HttpServletRequest request) {
User user = (User) session.getAttribute(Const.CURRENT_USER);//Const 是写的常量
if (user == null) {
return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(), "用户未登录,请登录管理员");
}
if (iUserService.checkAdminRole(user).isSuccess()) {
String path = request.getSession().getServletContext().getRealPath("upload");
String targetFileName = iFileService.upload(file, path);
String url = PropertiesUtil.getProperty("ftp.server.http.prefix") + targetFileName;
Map fileMap = Maps.newHashMap();
fileMap.put("uri", targetFileName);
fileMap.put("url", url);
return ServerResponse.createBySuccess(fileMap);
} else {
return ServerResponse.createByErrorMessage("无权限操作");
}
}富文本编辑器的方法的使用（Controller）：
@RequestMapping("richtext_img_upload.do")
@ResponseBody
public Map richtextImgUpload(HttpSession session, @RequestParam(value = "upload_file", required = false) MultipartFile file, HttpServletRequest request, HttpServletResponse response) {
Map resultMap = Maps.newHashMap();
User user = (User) session.getAttribute(Const.CURRENT_USER);
if (user == null) {
resultMap.put("success", false);
resultMap.put("msg", "请登录管理员");
return resultMap;
}
//富文本中对于返回值有自己的要求,我们使用是simditor所以按照simditor的要求进行返回
// {
// "success": true/false,
// "msg": "error message", # optional
// "file_path": "[real file path]"
// }
if (iUserService.checkAdminRole(user).isSuccess()) {
String path = request.getSession().getServletContext().getRealPath("upload");
String targetFileName = iFileService.upload(file, path);
if (StringUtils.isBlank(targetFileName)) {
resultMap.put("success", false);
resultMap.put("msg", "上传失败");
return resultMap;
}
String url = PropertiesUtil.getProperty("ftp.server.http.prefix") + targetFileName;
resultMap.put("success", true);
resultMap.put("msg", "上传成功");
resultMap.put("file_path", url);
response.addHeader("Access-Control-Allow-Headers", "X-File-Name");
return resultMap;
} else {
resultMap.put("success", false);
resultMap.put("msg", "无权限操作");
return resultMap;
}
}
