1、上传富文本内容
前端的富文本内容传到后端，将富文本内容拼接成html页面代码，将内容转换成html文件上传到服务器指定位置进行存储。
String profile = "/data/xiangmu";//linux服务器上项目文档存放目录
String domain = "http://yuming.com";//项目访问的域名或者ip+端口
String path = "/" + currentTimeMillis() + RandomStringUtils.randomAlphanumeric(8) + ".html";
String url = domain + "/upload" +path;
String fileName = profile + "/upload" + path;
try {
PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(fileName)));
String str = "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/></head><body>\n" +
"document.getDocContent()"+ "</body></html>";
out.println(str);
if(out!=null) out.close();
} catch (IOException e) {
throw new ServiceException("文档新建失败，请重新编辑。");
}
2、上传图片或文件
public RestResult<FeedImportEntity> importPictures(MultipartFile file) {
String profile = "/data/xiangmu";//linux服务器上项目文档存放目录
String domain = "http://yuming.com";//项目访问的域名或者ip+端口
try {
String avatar = FileUploadUtils.upload(profile+"/upload", file);
avatar = avatar.replaceFirst ("/profile/","/");//处理成项目nginx配置的域名访问格式
String url = domain + avatar;//上传成功之后图片访问的url
return RestResult.success("上传成功", url);
} catch (IOException e) {
logger.error("上传反馈图片(异常):" + e.getMessage(), e);
return RestResult.error("上传失败");
}
}

3、删除服务器上的文件。
public boolean deleteServerFile(Long docId){
boolean delete_flag = false;
String domain = "http://yuming.com";//项目访问的域名或者ip+端口
String profile = "/data/xiangmu";//linux服务器上项目文档存放目录
//文档的URL地址
String urlPath = documentMapper.selectDocumentUrl(docId);//从数据库中获取文件存放路径
urlPath = urlPath.replace(domain,"");
//File file = new File(filePath);/data/xiangmu/uploadPath
//File file = new File(File.separator +"data" + File.separator + "ruoyi" + File.separator + "uploadPath" + File.separator + "upload"+ File.separator, "9e38014f8aaf99e0d1c509903ec4cd79.png");
File file = new File(profile+urlPath);
if (!file.exists()) {
return delete_flag;
}
try{
delete_flag = file.delete();
}catch (Exception e){
e.printStackTrace();
}
return delete_flag;
}
4、vue前端页面展示文件。
methods: {
/** 浏览文档 */
handleBrowse(row){
const docType = row.docType;
const docUrl = row.docPath;
if(docType == "word" || docType == "excel" || docType == "ppt"){//判断文档类型（假代码）
const UrlEncode = encodeURIComponent(docUrl);
//Word、Excel、PPT文档
window.location.href = "http://view.officeapps.live.com/op/view.aspx?src="+UrlEncode;
}else{//PDF文档、文本文件、静态图片、音频文件、视频文件等
window.location.href = docUrl;
}
},
}
