Routing with AngularJS and Spring Boot involves setting up two separate routing systems: one for the frontend using AngularJS and another for the backend using Spring Boot. AngularJS will handle client-side routing for the frontend, while Spring Boot will handle server-side routing and API endpoints for the backend.

Here's a step-by-step guide to set up routing with AngularJS and Spring Boot:

  1. Set Up AngularJS for Frontend Routing:

    • Create an AngularJS application by including the AngularJS library in your HTML file. You can use a CDN or download the library locally.

    • Define your AngularJS app module and configure the routing using the ngRoute module or ui-router module. For this example, we'll use ngRoute.

    • Install the ngRoute module (if not already installed) using npm:

    npm install angular-route --save
    • Configure the routes in your AngularJS app:
    // app.js var app = angular.module('myApp', ['ngRoute']); app.config(function($routeProvider) { $routeProvider .when('/', { templateUrl: 'views/home.html', controller: 'HomeController' }) .when('/about', { templateUrl: 'views/about.html', controller: 'AboutController' }) .otherwise({ redirectTo: '/' }); });
  2. Create Frontend Views and Controllers:

    • Create the frontend views (HTML files) for each route defined in your AngularJS app (views/home.html and views/about.html in this example).

    • Create the corresponding controllers for each view (HomeController and AboutController in this example).

  3. Set Up Spring Boot for Backend Routing:

    • Create a Spring Boot application with Spring Web dependencies.

    • Define your backend routing and API endpoints using Spring Boot's @Controller and @RequestMapping annotations.

    // import org.springframework.web.bind.annotation.RestController; import org.springframework.web.bind.annotation.RequestMapping; @RestController public class BackendController { @RequestMapping("/api/data") public String getData() { return "Data from the backend"; } }
  4. Configure the Frontend to Interact with Backend API:

    • In your AngularJS controllers, use AngularJS's $http service to interact with the backend API.
    // HomeController.js app.controller('HomeController', function($scope, $http) { $scope.message = 'Loading data...'; $http.get('/api/data') .then(function(response) { $scope.message =; }) .catch(function(error) { $scope.message = 'Error fetching data from the backend'; }); });
  5. Serve Frontend and Backend Together:

    • Host your AngularJS frontend and Spring Boot backend together, either on the same domain or on separate ports. If you're using Spring Boot's embedded Tomcat, it will serve both frontend and backend by default.
  6. Test the Application:

    • Start your Spring Boot application, and it should serve the frontend and backend together.

    • Access your application through the specified URL (e.g., http://localhost:8080/), and AngularJS should handle client-side routing while Spring Boot handles server-side routing and API requests.

Remember to configure CORS (Cross-Origin Resource Sharing) settings in your Spring Boot application if your frontend is hosted on a different domain than your backend.

This guide provides a basic setup for routing with AngularJS and Spring Boot. Depending on your application's complexity and requirements, you may need to customize the routing further and add more features to your frontend and backend.
