SpringBoot后端百度富文本编辑器的做法(Java)

1.后端加载百度富文本编辑器的配置文件congfig.json,本项目放在resources下的static.ueditor下

springBoot下后端百度富文本编辑器的写法

congfig.json:

{
    /* 上传图片配置项 */
    "imageActionName": "uploadimage", /* 执行上传图片的action名称 */
    "imageFieldName": "upfile", /* 提交的图片表单名称 */

                                /* {filename} 会替换成原文件名,配置这项需要注意中文乱码问题 */
                                /* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */
                                /* {time} 会替换成时间戳 */
                                /* {yyyy} 会替换成四位年份 */
                                /* {yy} 会替换成两位年份 */

}

2.直接写后端的controller,前端直接调用接口dispatch接口,初始化的时候action的值是config空,本文只写了上传图片当action的值是uploadimage上传图片

                CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(

                        if (multipartFile != null) {
                            // 项目在容器中实际发布运行的根路径
                            String realPath = uploadFolder;

                            // 设置存放图片文件的路径

                            //组装百度上传图片返回连接
                            JSONObject jsonobject = new JSONObject();
                            jsonobject.put("state", "SUCCESS");

                            response.setContentType("application/json;charset=utf-8");

    private String readFile(HttpServletRequest request, String file) throws IOException {

        StringBuilder builder = new StringBuilder();

        try {
            InputStream inputStream = ClassLoader.getSystemResourceAsStream(file);
            InputStreamReader reader = new InputStreamReader(inputStream, "UTF-8");
            BufferedReader bfReader = new BufferedReader(reader);

            }

            bfReader.close();

        } catch (UnsupportedEncodingException e) {
            // 忽略
        }

        JSONObject jSONObject = filter(builder.toString());
        String result = jSONObject.toJSONString();

            }

            return callbackName + "(" + result + ");";

        } else {
            return result;

    // 过滤输入字符串, 剔除多行注释以及替换掉反斜杠

     * callback参数验证
     */

        if (name.matches("^[a-zA-Z_]+[\\w0-9_]*$")) {
            return true;
        }
        return false;
    }


}

3.上传图片的路径和域名配置,图片上传到后端项目的data/file目录下,file.upload.nama是后端项目域名

file.uploadFolder=/data/file/

#上传文件本地域名
file.upload.nama=http://www.xxx.com
