この記事ではspringbootがどのようにftpファイルのアップロードを実現し、フロントエンドフレームワークでアップロードされた画像を受信し、画像をftpピクチャサーバにアップロードするかについて説明します.もちろん、まずftpサーバを構築する必要があります.
1)pom.xml ftp依存性の追加

 
     commons-net
     commons-net
     3.3

2)ftpアップロードツールクラスの作成

package com.xiaoi.document.split.common.utils;

import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.io.InputStream;

/**
 * FtpUtil    ftp     
 *
 * @Author Yuan Jingshan
 * @Date 2018-05-09
 */
@Component
public class FtpUtil {

    //ftp   ip  
    private static final String FTP_ADDRESS = "172.16.205.28";
    //   
    private static final int FTP_PORT = 21;
    //   
    private static final String FTP_USERNAME = "gzxiaoiftp";
    //  
    private static final String FTP_PASSWORD = "gzxiaoi";
    //    
    public final String FTP_BASEPATH = "/home/ftp/develop/";

    public boolean uploadFile(String originFileName, InputStream input) {
        boolean success = false;
        FTPClient ftp = new FTPClient();
        ftp.setControlEncoding("GBK");
        try {
            int reply;
            ftp.connect(FTP_ADDRESS, FTP_PORT);//   FTP   
            ftp.login(FTP_USERNAME, FTP_PASSWORD);//   
            reply = ftp.getReplyCode();
            if (!FTPReply.isPositiveCompletion(reply)) {
                ftp.disconnect();
                return success;
            }
            ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
            ftp.makeDirectory(FTP_BASEPATH);
            ftp.changeWorkingDirectory(FTP_BASEPATH);
            ftp.storeFile(originFileName, input);
            input.close();
            ftp.logout();
            success = true;
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (ftp.isConnected()) {
                try {
                    ftp.disconnect();
                } catch (IOException ioe) {
                }
            }
        }
        return success;
    }
}

3)作成制御層処理ファイルアップロード

package com.xiaoi.document.split.management.common.ftp;

import com.xiaoi.document.split.common.utils.FtpUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

/**
 * FtpUtil    ftp     
 *
 * @Author Yuan Jingshan
 * @Date 2018-05-30
 */
@Controller
@RequestMapping(value = "/docsplit/ftp")
@Slf4j
public class FtpController {

    @Autowired
    private FtpUtil ftpUtil;

    @RequestMapping(value = "/upload", method = RequestMethod.POST)
    @ResponseBody
    public Map, String> uploadImg(@RequestParam("file") MultipartFile file, HttpServletRequest request) throws IOException {
        Map, String> map = new HashMap<>();
        map.put("code", "0");
        map.put("msg", "      ");
        String fileName = file.getOriginalFilename();
        log.info("    :{}", fileName);
        InputStream inputStream = file.getInputStream();
        String filePath = null;
        Boolean flag = ftpUtil.uploadFile(fileName, inputStream);
        if (flag == true) {
            log.info("      !");
            filePath = ftpUtil.FTP_BASEPATH + fileName;
            map.put("code", "1");
            map.put("msg", "      ");
        }
        map.put("path", filePath);
        return map; //       ，      ngnix     +filePath,     ngnix         
    }
}

4)フロントエンドでlayuiファイルを使ってアップロード

class="layui-form-item">
    class="layui-form-label-block-resource">  
    class="layui-input-block-new-resource">
        id="uploadResourceFile" name="title" lay-verify="title" autocomplete="off" class="layui-input" type="text" style="width: 70%; float: left;">


</span><span style="color:#e8bf6a;">    </span><span style="color:#9876aa;">layui</span>.<span style="color:#9876aa;">use</span>(<span style="color:#6a8759;">'upload'</span><span style="color:#cc7832;">, </span><span style="color:#cc7832;"><strong>function</strong></span>(){
