Ueditor自定义上传文件通过SpringMVC上传图片到FTP

╰+攻爆jí腚メ 2022-02-27 11:50 346阅读 0赞

### 一、修改Ueditor的config.json的文档图片访问路径前缀改成FTP对外暴露的访问地址 ###

"imageUrlPrefix": "http://192.168.85.98:8280/up/"

### 二、初始化Ueditor时绑定自定义文件上传方法  ###

<div id="content">
        <script id="editor" type="text/plain" style="width:100%;height:100%;"></script>
        <script type="text/javascript">
            var ue = UE.getEditor('editor');
            //对编辑器的操作最好在编辑器ready之后再做
            ue.ready(function() {			 		  
                var content=`${orginMemo.textContent}`;
                ue.setContent(content);			    
                UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
                UE.Editor.prototype.getActionUrl = function(action) {
                    if (action == 'uploadimage' || action == 'uploadscrawl') {
                        return 'http://172.25.10.42:8080/wx/ueditor/file/uploadFile.to';//这就是自定义的上传地址
                    } else if (action == 'uploadvideo') {
                        return '';
                    } else {
                         return this._bkGetActionUrl.call(this, action);
                    }
                }
            });
        </script>
    </div>

### 三、自定义SpringMVC后端文件上传方法 ###

@RequestMapping("/ueditor/file")
    public class UeditorController {
    	
    	@RequestMapping("/uploadFile")
    	@ResponseBody
    	public Map<String,Object> uploadFile(HttpServletRequest request, HttpServletResponse response){
    		System.out.println("开始保存文件");
    		Map<String,Object> map = new HashMap<String,Object>();
    		//将上下文初始化给多部分解析器
    		CommonsMultipartResolver resolver=new CommonsMultipartResolver(request.getSession().getServletContext());
    		if(resolver.isMultipart(request)){
    			MultipartHttpServletRequest  multipartRequest=(MultipartHttpServletRequest) request;
    			Iterator iter=multipartRequest.getFileNames();
    			try {
    				String[] now = DateTimeUtil.getCurDateTime("yyyy-MM-dd").split("-");
    				String subPath_1 = "/Ueditor/";
    				String subPath_2 =  now[0] + "/" + now[1] + "/" + now[2];
    				String ftpFilePath = subPath_1+subPath_2;
    				String ftpServer = "192.168.85.98";
    				String ftpUser = "xxx";
    				String ftpPassword = "xxx";
    				String fileSaveName = "";
    				String uid = "0";
    				while (iter.hasNext()) {
    					MultipartFile file =multipartRequest.getFile(iter.next().toString());
    					if(file!=null){
    						long size = file.getSize();
    						System.out.println("size="+size);
    						//将上传的文件转换成输入流  
    						InputStream inStream = file.getInputStream();
    						System.out.println(file.getOriginalFilename());
    						String fileName = file.getOriginalFilename();
    						fileSaveName = DateTimeUtil.getCurDateTime("yyyyMMddHHmmssSSS")+"_"+uid+fileName.substring(fileName.lastIndexOf("."));
    						String path = this.ftpUploadImg(inStream, fileSaveName, ftpFilePath, request, ftpServer, ftpUser, ftpPassword);
    						map.put("path", ftpFilePath);
    						map.put("filename", fileSaveName);
    		                    
    						map.put("original", fileName);
    						map.put("name", fileSaveName);
    						map.put("url", ftpFilePath+"/"+fileSaveName);
    						map.put("state", "SUCCESS");
    						map.put("type", ".jpg");
    						map.put("size", "99697");
    					}
    				}
    			} catch (Exception e) {
    				map.put("msg", "fail");
    				e.printStackTrace();
    			}
    			
    		}
    		return map;
    	}
    	
    	private String ftpUploadImg(InputStream in, String docName, String dir, HttpServletRequest request, 
    			String ftpServer, String ftpUser, String ftpPassword) {
    	
    	FileUpload ftp = null;
    	
    	try {
    		ftp = new FileUpload();
    		if (ftp.ftpConnect(ftpServer, ftpUser, ftpPassword)){
    		
    			ftp.getFtpClient().setRemoteVerificationEnabled(false);
    			
    			if(!ftp.ftpExistDir(dir)) {
    				ftp.ftpMakeDir(dir);
    			}
    			
    			if (ftp.ftpUpload(dir, StringUtil.toISO(docName),in)){
    				System.out.println(dir);
    			} 
    		}
    	} catch (Exception e) {
    		e.printStackTrace();
    		System.out.println(e.getMessage());
    		dir = "";
    	} finally {
    		if(ftp != null) ftp.ftpDisconnect();
    	}
    	
    	if(!dir.equals("")){
    		return dir;
    	}else{
    		return "";
    	}
    }
    	
    	
    
    }

核心是需要返回：

map.put("path", ftpFilePath);
    map.put("filename", fileSaveName);     
    map.put("original", fileName);
    map.put("name", fileSaveName);
    map.put("url", ftpFilePath+"/"+fileSaveName);
    map.put("state", "SUCCESS");
    map.put("type", ".jpg");
    map.put("size", "99697");
