    IFileService.java

    service包下新建IFileService.java

    package com.mmall.service;
    
    import org.springframework.web.multipart.MultipartFile;
    
    /**
     * @Author: Geekerstar(jikewenku.com)

     * @Description:
     */
    public interface IFileService {
        String upload(MultipartFile file, String path);
    }
    

    FileServiceImpl.java

    创建实现类FileServiceImpl.java

    package com.mmall.service.impl;
    
    import com.google.common.collect.Lists;
    import com.mmall.service.IFileService;
    import com.mmall.util.FTPUtil;
    import org.slf4j.Logger;

    import org.springframework.web.multipart.MultipartFile;
    
    import java.io.File;
    import java.io.IOException;
    import java.util.UUID;
    
    /**

    @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);
            String uploadFileName = UUID.randomUUID().toString()+"."+fileExtensionName;
            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);
            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,删除upload下面的文件
                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();
        }
    
    }
    

    FTPUtil.java

    util包下创建文件上传工具类FTPUtil.java

    package com.mmall.util;

    测试文件上传

    接下来测试两种文件上传,在index.jsp中编写如下代码,完成测试,我们使用是simditor所以按照simditor的要求进行返回。
