spring boot 使用kindeditor上传传照片到nginx

可以批量上传图片

一、前后台

1.1 引入

        <script src="/js/appjs/apply/jquery-1.12.4.min.js" type="text/javascript" charset="utf-8"></script>
         <link href="/kindeditor/themes/default/default.css" type="text/css" rel="stylesheet">
        <script charset="utf-8" src="/kindeditor/kindeditor-all.js"></script>
        <script charset="utf-8" src="/kindeditor/lang/zh_CN.js"></script>

1.2 初始化组建

<script>
            KindEditor.ready(function(K) {
                var editor = K.editor({
                    filePostName:"uploadFile",//上传组件名
                    uploadJson: '/apply/pic/upload',//上传地址
                    dir:"image"//类型

                });
                K('#J_selectImage').click(function() {
                    editor.loadPlugin('multiimage', function() {
                        editor.plugin.multiImageDialog({
                            clickFn : function(urlList) {
                                var div = K('#J_imageView');
                                div.html('');
                                K.each(urlList, function(i, data) {
                                    div.append('<img src="' + data.url + '">');
                                });
                                editor.hideDialog();
                            }
                        });
                    });
                });


<input type="button" style="100px;height:50px;"  id="J_selectImage" value="批量上传" />
                    
<div id="J_imageView">

1.3 上传的方法

@RequestMapping(value="/pic/upload",method=RequestMethod.POST,produces=MediaType.TEXT_PLAIN_VALUE)
    @ResponseBody
    public String upload(@RequestParam("uploadFile") MultipartFile uploadFile , 
            HttpServletRequest request,HttpServletResponse response) throws Exception {
        String sessionId = request.getSession().getId();
        System.out.println("调用上传");
        Map result = picService.uploadPicture(uploadFile,sessionId);
        String json = JsonUtils.objectToJson(result);
        return json;
    }

二、公共ftp方法

注意：ftp 前面是没有http的

//加载配置文件的值
@Value("${FTP_ADDRESS}")
private String FTP_ADDRESS;
@Value("${FTP_PORT}")
private int FTP_PORT;
@Value("${FTP_USERNAME}")
private String FTP_USERNAME;
@Value("${FTP_PASSWORD}")
private String FTP_PASSWORD;
@Value("${FTP_BASEPATH}")
private String FTP_BASEPATH;
@Value("${IMAGE_BASE_URL}")
private String IMAGE_BASE_URL;

FTP_ADDRESS: 47.98.184.30
FTP_PORT: 21
FTP_USERNAME: ftpuser
FTP_PASSWORD: ftpuser
FTP_BASEPATH: /home/ftpuser/img

@Override
    public Map uploadPicture(MultipartFile uploadFile,String sessionId) {
        Map resultMap = new HashMap<>();
        // 修改文件名
        String oldName = uploadFile.getOriginalFilename();
        System.out.println("oldName=" + oldName);
        String newName = IDUtils.genImageName() + oldName.substring(oldName.lastIndexOf("."));
        System.out.println("newName=" + newName);
        
        // 上传文件到ftp服务器
        String filePath = new DateTime().toString("/yyyy/MM/dd");
        try {
            boolean uploadResult = FtpUtil.uploadFile(FTP_ADDRESS, FTP_PORT, FTP_USERNAME, FTP_PASSWORD,
                    FTP_BASEPATH, filePath, newName, uploadFile.getInputStream());
            if(!uploadResult) {
                // error 成功是0  失败是1
                resultMap.put("error", 1);
                resultMap.put("message", "上传失败");
                return resultMap;
            }
            // 上传成功
            resultMap.put("error", 0);
            String saveUrl = filePath + "/" + newName;
            System.out.println("url=" + saveUrl);
            resultMap.put("url", IMAGE_BASE_URL + saveUrl);
            
            ApplyImgExample example = new ApplyImgExample();
            Criteria createCriteria = example.createCriteria();
            createCriteria.andSessionidEqualTo(sessionId);
            List<ApplyImg> imgList = applyImgMapper.selectByExample(example);
            System.out.println("imgList size" + imgList.size());
            if(imgList != null && imgList.size() > 0){
                ApplyImg applyImg = imgList.get(0);
                if(StringUtils.isBlank(applyImg.getImgpath2())){
                    applyImg.setImgpath2(saveUrl);
                    applyImgMapper.updateByPrimaryKeySelective(applyImg);
                } else {
                    applyImg.setImgpath3(saveUrl);
                    applyImgMapper.updateByPrimaryKeySelective(applyImg);
                }
            } else {
                ApplyImg applyImg = BeanUtils.getApplyImg(saveUrl, sessionId);
                applyImgMapper.insert(applyImg);
            }
            
            return resultMap;
        } catch (IOException e) {
            e.printStackTrace();
            resultMap.put("error", 1);
            resultMap.put("message", "上传出现异常");
            return resultMap;
        }
    }
