Use and Configure UEditor with a Java Backend

UEditor consists of a browser editor and a server-side action endpoint used for configuration, uploads, image listing, and related operations.

Initialize the editor with a stable element ID and explicit options:

<script id="editor" type="text/plain"></script>
<script>
const editor = UE.getEditor("editor", {
  initialFrameHeight: 420,
  autoHeightEnabled: false,
  serverUrl: "/ueditor/controller"
});
</script>

The backend should return the configuration and action-specific JSON schema expected by the installed UEditor release. Keep filesystem paths separate from public URLs, generate filenames server-side, and return normalized UTF-8 responses.

Restrict toolbar features to those the product actually needs. Validate upload size, type, content, count, and authorization on the server. Store files outside executable directories and prevent path traversal.

Rich-text HTML is untrusted input. Sanitize it with an allowlist before storage or rendering, enforce CSRF protection, and apply a content security policy. UEditor is legacy software, so review known vulnerabilities and consider a maintained editor before deploying a new public system.
