An extra tip to save the effort of having to repetitively “cd” to navigate to client project home every time is to configure the terminal’s default directory to be “/learn/fullstack/ngspring/demo-app-client”.,3. Click finish. The “demo-app-server” project will be created in your workspace. Next, right-click on the project and go to “Spring Tools”, and click “Add Boot Devtools.” This will enable the server side code watch and hot deployment features.,Once you have a terminal open, run the command “npm start”. The client project will start with its own server listening on port 4200 and any changes in the client project directory will be watched and automatically picked up. ,1. URL bookmarking will not work. You will either always have to start from the home page or you will need to add extra configuration within the project to resolve urls at the Spring MVC level.

4. Now, like any other awesome tutorial, let’s create a simple REST controller to return a greeting message and map it to URL “/api/hello”.

package org.demo.web;

import org.springframework.web.bind.annotation.RequestMapping;

@org.springframework.web.bind.annotation.RestController
public class RestController {
   @RequestMapping("/api/hello")
   public String greet() {
      return "Hello from the other side!!!";
   }
}
