Spring 4 MVC+AngularJS Routing Example using ngRoute

This post demonstrates integrating AngularJS with Spring MVC 4, focusing on routing using ngRoute module. We will discuss route configuration using $routeProvider, accessing route parameters using $routeParams, discuss route configuration details with template, templateUrl, controller, redirectTo & resolve keys. Let’s get going.


In our application, Client side is based on AngularJS, demonstrating route configuration and usage. Server side is based on Spring , serving HTML templates using velocity templates and content using Spring REST API. This is what our final Application will look like:

Spring4MVCAngularJSRoutingExample_img1
Spring4MVCAngularJSRoutingExample_img2

If you have any doubts on routing in AngularJS, please refer to AngularJS Routing Tutorial to know the in-depth details.

Let’s get started.

Following technologies being used:

  • Spring 4.2.0.RELEASE
  • AngularJS 1.4.4
  • Maven 3
  • JDK 1.7
  • Eclipse Mars.1 Release (4.5.1)

1. Client Side

Client side of our Application is AngularJS based. If you would like to add AngularJs in your skill set, Detailed AngularJS Tutorial is available for you to deep dive in one of the most popular Javascript Meta framwework.

Route configuration:

Configure routes using AngularJS ngRoute module. Route configuration is done in AngularJS module’s config function, using $routeProvider service.
In our example, we have two types of routes : itemList routes & itemDetails routes.Both are shown below. Look specially at how the resolve is used to trigger service for communicating servers. And eventually the promise(named ‘async’ below) is passed into controllers to fetch the item lists and details. For more in depth details, please refer to AngularJS Routing Tutorial

app.js

'use strict';

var App = angular.module('myApp',['ngRoute']);

App.config(['$routeProvider', function($routeProvider) {
	$routeProvider
		.when('/items/computers', {
			templateUrl: 'items/computers',
			controller : "ItemListController as itemListCtrl",
			resolve: {
                async: ['ItemService', function(ItemService) {
                    return ItemService.fetchAllItems('computers');
               	}]
            }
		})
		.when('/items/phones', {
			templateUrl: 'items/phones',
			controller : "ItemListController as itemListCtrl",
			resolve: {
                async: ['ItemService', function(ItemService) {
                    return ItemService.fetchAllItems('phones');
               	}]
            }
		})
		.when('/items/printers', {
			templateUrl: 'items/printers',
			controller : "ItemListController as itemListCtrl",
			resolve: {
                async: ['ItemService', function(ItemService) {
                    return ItemService.fetchAllItems('printers');
               	}]
            }
		})
		.when('/items/computerdetails/:id', {
			templateUrl: 'items/computerdetails',
			controller : "ItemDetailsController as itemDetailsCtrl",
			resolve: {
                async: ['ItemService','$route', function(ItemService , $route) {
                    return ItemService.fetchSpecificItem('computers',$route.current.params.id);
               	}]
            }
		})
		.when('/items/phonedetails/:id', {
			templateUrl: 'items/phonedetails',
			controller : "ItemDetailsController as itemDetailsCtrl",
			resolve: {
                async: ['ItemService','$route', function(ItemService , $route) {
                    return ItemService.fetchSpecificItem('phones',$route.current.params.id);
               	}]
            }
		})
		.when('/items/printerdetails/:id', {
			templateUrl: 'items/printerdetails',
			controller : "ItemDetailsController as itemDetailsCtrl",
			resolve: {
                async: ['ItemService','$route', function(ItemService , $route) {
                    return ItemService.fetchSpecificItem('printers',$route.current.params.id);
               	}]
            }
		})
		
		.otherwise({redirectTo:'/items/computers'});		
}]);

Service Creation:

Configure Service which will eventually communicate with our Spring based server. For any doubts on service setup, please refer to AngularJS Services Tutorial.

ItemService.js


'use strict';

App.factory('ItemService', ['$http', '$q', function($http, $q){

	return {
		
			fetchAllItems: function(category) {
					return $http.get('http://localhost:8080/Spring4MVCAngularJSRoutingExample/item/'+category)
							.then(
									function(response){
										return response.data;
									}, 
									function(errResponse){
										console.error('Error while fetching Items');
										return $q.reject(errResponse);
									}
							);
			},
		    
			fetchSpecificItem: function(category,id) {
				return $http.get('http://localhost:8080/Spring4MVCAngularJSRoutingExample/item/'+category+'/'+id)
						.then(
								function(response){
									return response.data;
								}, 
								function(errResponse){
									console.error('Error while fetching specific Item');
									return $q.reject(errResponse);
								}
						);
			}
	};

}]);

Controller Creation:

Create controller for Item lists and details. For any doubts on service setup, please refer to AngularJS Controllers Tutorial.

Item List controller is shown below:
ItemListController.js

'use strict';

App.controller('ItemListController', ['async', function(async) {
          var self = this;
          self.items=async;
}]);

Item Details controller is shown below:
ItemDetailsController.js

'use strict';

App.controller('ItemDetailsController', ['async', function(async) {
          var self = this;
          self.item=async;
}]);

Configure Welcome Page:

Shown below is the main page, containings URL’s to routes for lists, and ng-viw component which will eventually be filled via select routes template.

2. Server Side

Spring Configuration Class:

HelloWorldConfiguration.java

package com.websystique.springmvc.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.velocity.VelocityConfigurer;
import org.springframework.web.servlet.view.velocity.VelocityView;
import org.springframework.web.servlet.view.velocity.VelocityViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springmvc")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter{
	
	
	@Bean
	public VelocityConfigurer velocityConfig() {
	    VelocityConfigurer velocityConfigurer = new VelocityConfigurer();
	    velocityConfigurer.setResourceLoaderPath("/WEB-INF/velocity/");
	    return velocityConfigurer;
	}
	
	@Override
	public void configureViewResolvers(ViewResolverRegistry registry) {
		VelocityViewResolver viewResolver = new VelocityViewResolver();
		
		viewResolver.setViewClass(VelocityView.class);
		viewResolver.setCache(true);
		viewResolver.setPrefix("");
		viewResolver.setSuffix(".html");
		viewResolver.setExposeSpringMacroHelpers(true);

		registry.viewResolver(viewResolver);
	}

	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
	}

}

Create WelcomePage controller

IndexController.java

package com.websystique.springmvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/")
public class IndexController {//Serves main index.html

	  	@RequestMapping(method = RequestMethod.GET)
	    public String getIndexPage() {
	        return "index";
	    }
	  
	  	
}

Create Template Controller handling the requests for templates:

MainTemplateController.java

package com.websystique.springmvc.controller;

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

@Controller
@RequestMapping("/items")
public class MainTemplateController {
	
    @RequestMapping(value="/computers")
    public String getComputersTemplate() {
    	return "template/item_computers";	
    }

    @RequestMapping(value="/phones")
    public String getPhonesTemplate() {
    	return "template/item_phones";	
    }

    @RequestMapping(value="/printers")
    public String getPrintersTemplate() {
    	return "template/item_printers";	
    }

    @RequestMapping(value="/computerdetails")
    public String getComputerDetailsTemplate() {
    	return "template/item_computer_details";	
    }

    @RequestMapping(value="/phonedetails")
    public String getPhoneDetailsTemplate() {
    	return "template/item_phone_details";	
    }

CORS Filter: Creating Filter to handle Same Origin Policy related issues


package com.websystique.springmvc.configuration;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;


public class CORSFilter implements Filter {

	public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
		HttpServletResponse response = (HttpServletResponse) res;
		response.setHeader("Access-Control-Allow-Origin", "*");
		response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
		response.setHeader("Access-Control-Max-Age", "3600");

		chain.doFilter(req, res);
	}

	public void init(FilterConfig filterConfig) {}

	public void destroy() {}

}

Create Spring Initializer class

Look at how we are registering CORS filter with Spring configuration, which will help us to get away with Same Origin Policy issues.

package com.websystique.springmvc.configuration;

import javax.servlet.Filter;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class HelloWorldInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
 
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { HelloWorldConfiguration.class };
    }
  
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }
  
    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
    
    @Override
    protected Filter[] getServletFilters() {
    	Filter [] singleton = { new CORSFilter() };
    	return singleton;
	}
 
}

Deploy & Run

Now build the war (either by eclipse as was mentioned in previous tutorials) or via maven command line( mvn clean install). Deploy the war to a Servlet 3.0 container . Since here i am using Tomcat, i will simply put this war file into tomcat webapps folder and click on startup.bat inside tomcat/bin directory.

Open browser and browse at http://localhost:8080/Spring4MVCAngularJSRoutingExample/. it will be redirected to /item/computes [look at ‘otherwise’ part in $routeProvider config]. Check the URL in browser.

Spring4MVCAngularJSRoutingExample_img1

You can also open the developer tools in chrome and check the request sent for each operation to server and response received.

Now click on printers link, you should see all printers list in bottom panel.

Spring4MVCAngularJSRoutingExample_img3

Now click on specific printer link [in Model column], you should see the details of that specific printer in bottom panel.Also check the URL in browser.

Spring4MVCAngularJSRoutingExample_img4

That’s it.
