Currently, I develop with java / spring-boot / log4j2 , and as much as I have searched I have not seen anything interesting to log directly to a web page in real-time (something like swagger style with requests, which is by configuration without having to write code) .
Do you know anything?
You need Javascript to modify the DOM of a webpage, not Java.
You could use Spring to send Server-Sent-Events (SSE) to a frontend JS library, or host a WebSocket or other REST API on some web server and use AJAX to issue requests, upon which the DOM is modified as part of a response, but this really has nothing to do with Java/Spring/log4j
If you want a packaged distribution of Spring w/ some Javascript framework, JHipster is a popular option.
