SpringMvc upload background images and rich text JAVA upload using ftp server function

FTP configuration files:

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：

<! - file upload ->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10485760"/> <!-- 10m -->
    <property name="maxInMemorySize" value="4096" />
    <property name="defaultEncoding" value="UTF-8"></property>

File Upload Interface

import org.springframework.web.multipart.MultipartFile;

/**
 * Created by geely
 */
public interface IFileService {

    String upload(MultipartFile file, String path);
}

 

File upload implementation class

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();
    }

}

Use file upload methods (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");
    }
}

Use the rich text editor (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;
        }
    }
