bootstrap-fileinput多圖片上傳

在頁面寫一個input框：

<input id="subGraphAddress1" name="subGraphAddress" type="file" accept="image/jpg,image/png,image/gif,image/jpeg" />

頁面導入的css和js文件：

<link href="/static/assets/bootstrap-fileinput-4.4.8/css/fileinput.min.css" rel="stylesheet" />
<link href="/static/assets/bootstrap-fileinput-4.4.8/css/fileinput-rtl.min.css" rel="stylesheet" />
<script src="/static/assets/bootstrap-fileinput-4.4.8/js/fileinput.min.js"></script>
<script src="/static/assets/bootstrap-fileinput-4.4.8/js/zh.js"></script>

javascript代碼寫在body外面：

<script th:inline="javascript">
    /*圖片上傳 */
    $("#subGraphAddress1")
            .fileinput({
                theme : 'fa',
                dropZoneTitle : "請上傳小於5M的圖片！",
                uploadUrl : "saveAddress",
                language : "zh",
                autoReplace : true,
                showCaption : false,
                showUpload : true,
                overwriteInitial : true,
                uploadAsync : true,
                showUploadedThumbs : true,
                maxFileCount : 5,
                minFileCount : 1,
                initialPreviewShowDelete : false,
                showRemove : false,
                showClose : false,
                autoReplace : true,
                overwriteInitial : true,
                layoutTemplates : {
                    actionDelete:'',    //去掉圖片的刪除按鈕
                    actionUpload: '',
                },
                previewSettings : {
                    image : {
                        width : "100%",
                        height : "100%"
                    },
                }
            })
            
</script>

圖片上傳到ftp服務器的后台java代碼：

public ModelMap saveSubAddress(@RequestParam("subGraphAddress") MultipartFile subGraphAddress,
            HttpServletRequest request, HttpServletResponse response) {
        ModelMap map = new ModelMap();
        // 主圖的項目路徑
        String paFileName = subGraphAddress.getOriginalFilename();

        try {
            FtpUtil ftpUtil = new FtpUtil();
            FTPClient ftp = ftpUtil.getConnectionFTP(UploadFileUrlUtil.HOST_NAEM, UploadFileUrlUtil.PORT,
                    UploadFileUrlUtil.USER_NAME, UploadFileUrlUtil.PASSWORD);
            filename = FtpUtil.getFileName(subGraphAddress);

            boolean bool = ftpUtil.uploadFile(ftp, UploadFileUrlUtil.GetPath(UploadFileUrlUtil.BIG_PATH), filename,
                    subGraphAddress.getInputStream());
            if (bool) {
                url = UploadFileUrlUtil.GetPath(UploadFileUrlUtil.BIG_PATH) + filename;
                map.put("subGraphAddress", url);
                map.put("viceGraphName", filename);
                System.out.println("上傳成功！");
                boolean boolClose = ftpUtil.closeFTP(ftp);
                if (boolClose) {
                    System.out.println("關閉ftp連接成功！");
                } else {
                    System.out.println("關閉ftp連接失敗！");
                }
            } else {
                System.out.println("上傳失敗！");
            }

        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        return ReturnUtil.Success("加載成功", map, null);
    }

 遠程服務器的配置信息：

public class UploadFileUrlUtil {  
//    遠程服務器的配置信息
    public final static String HOST_NAEM="127.0.0.1";
    public final static Integer PORT=21;
    public final static String USER_NAME="123456";    //ftpuser
    public final static String PASSWORD="123456";
    public final static int LOCALHOST= 8080;
    
    public final static String BIG_PATH="/upload/picture/big/";  //主圖路徑
    public final static String SMALL_PATH="/upload/picture/small/";  //副圖的路徑
    public final static String VIDEO_PATH="/upload/picture/video/";  //視頻的路徑
    public final static String HOST= "http://192.168.0.140:8080";// 上傳的端口
    
    public static String GetPath(String path) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
        String date=sdf.format(new Date());
        return path+date+"/";
    }
}
