Java web application rapid development tool

We are planing to use AngularJS, Bootstrap, jQuery, Javascript, CSS for a web application development.

My boss is suggesting to build a tool that would read the metadata (could be from DB) and build the web application without or less coding. So that in future to add any new pages he would just create/edit the metadata.

To me it seems too complicated and may not be possible as it does not give flexibility. Please suggest.
