Jeecg富文本编辑器上传视频无法预览解决

jeecg使用的富文本编辑器是：tinyMCE富文本编辑器
tinyMCE中文文档：http://tinymce.ax-z.cn/

问题： 视频上传成功后，无法预览，通过查看标签元素发现video标签设置错误，内容为：

%0A%3Csource%20src%3D%22http%3A//192.168.1.107%3A8008/alliaceUniversity/sys/common/static/6-v_1634784386454.mp4%22%20type%3D%22video/mp4%22%20/%3E
可以播放的正确标签为:

<video width="100%" height="auto" src="http://192.168.1.107:8008/alliaceUniversity/sys/common/static/6-WhatIfIWanttoMoveFaster_1634720194226.mp4" controls="controls"></video>

解决前

解决后可以正常播放

解决思路：在视频上传成功后需要回显到富文本编辑器时，手动修改视频的标签然后回显到富文本编辑器。

 media_url_resolver: function (data, resolve) {
          console.log('media_url_resolver', data)
          try {
              let videoUri = encodeURI(data.url);
              let embedHtml = `<p>
                  <span
                      class="mce-object mce-object-video"
                      data-mce-selected="1"
                      data-mce-object="video"
                      data-mce-p-width="100%"
                      data-mce-p-height="auto"
                      data-mce-p-controls="controls"
                      data-mce-p-controlslist="nodownload"
                      data-mce-p-allowfullscreen="true"
                      data-mce-p-src=${videoUri} >
                      <video src=${data.url} width="100%" height="auto" controls="controls" controlslist="nodownload">
                      </video>
                  </span>
              </p>
              <p style="text-align: left;"></p>`;
              resolve({ html: embedHtml });
          } catch (e) {
              resolve({ html: "" });
          }
