Answer 1

Try to create a view(jsp/html/xhtml) and link the UI build output to that. you may use webpack as a build tool for UI(React) which will return bundle file.
Then it can be included to view using script tag. Please note you can use webpack-dev-server for UI development and try to use Proxy to consume the spring-mvc service. Its a recommended way. A folder containing all the JS under webapp can be used if your using Maven as build tool for java.
webpack reference : https://webpack.js.org/
