– Java 1.8
– Maven 3.3.9
– Spring Tool Suite – Version 3.8.1.RELEASE
– AngularJS
– BootStrap

II. Overview
1. Project Structure

http angularjs spring boot - project structure

2. Step to do

– Create SpringBoot project
– Create a simple model
– Create a Controller
– Create a RestController
– Create a index.html page
– Create an angularjs controller with GET & POST methods
– Run & Check result

III. Practices
1. Create SpringBoot project

– Open Spring Tool Suite, on main menu, choose File->New->Spring Starter Project, add project info, then press Next for needed dependencies:
For Template Engines, choose Thymeleaf
For Web MVC, choose Web->Web

			org.springframework.boot
			spring-boot-starter-test
			test

				spring-boot-maven-plugin
2. Create a simple model

Create a Customer model:

package com.javasampleapproach.angularjs.model;

public class Customer {
	private String firstname;
	private String lastname;
	
	public Customer(){}
	
	public Customer(String firstname, String lastname){
		this.firstname = firstname;
		this.lastname = lastname;
	}
	
	// firstname
	public String getFirstname() {
		return firstname;
	}
	public void setFirstname(String firstname) {
		this.firstname = firstname;
	}
	
	// lastname
	public String getLastname() {
		return lastname;
	}
	public void setLastname(String lastname) {
		this.lastname = lastname;
	}
}
3. Create a Controller

– Create a simple controller for providing an index.html view

package com.javasampleapproach.angularjs.controller;

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

@Controller
public class WebController {
	@RequestMapping(value="/",method = RequestMethod.GET)
    public String homepage(){
        return "index";
    }
}
4. Create a RestController

Create a RestController with 2 RequestMapping:
– GET request method that returns all customers.
– POST request method that uses for adding a new customer.

package com.javasampleapproach.angularjs.controller;

import java.util.ArrayList;
import java.util.List;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.javasampleapproach.angularjs.model.Customer;

@RestController
public class RestWebController {
	
	List cust = new ArrayList();
	
	@RequestMapping(value = "/getallcustomer", method = RequestMethod.GET)
	public List getResource(){
			return cust;
	}
	
	@RequestMapping(value="/postcustomer", method=RequestMethod.POST)
	public String postCustomer(@RequestBody Customer customer){
		cust.add(customer);
		
		return "Sucessful!";
	}
}
5. Create an index.html page

Create a simple index.html page with a form for posting a customer to server, and a button for getting all customers from remote server.

User Bootstrap & Angularjs:

6. Create an angularjs controller with GET & POST methods
MultipartFile – How to create Spring AngularJs MultipartFile application to download/upload files | SpringBoot + AngularJs + Bootstrap.

Create an angular controller file with 2 methods:
– POST method to post a customer’s info to server with url: /postcustomer
$http.post(‘/someUrl’, data, config).then(successCallback, errorCallback);

– GET method to get all customers from server with url: /getallcustomer
$http.get(‘/someUrl’, config).then(successCallback, errorCallback);

var app = angular.module('app', []);
app.controller('postcontroller', function($scope, $http, $location) {
	$scope.submitForm = function(){
		var url = $location.absUrl() + "postcustomer";
		
		var config = {
                headers : {
                    'Accept': 'text/plain'
                }
        }
		var data = {
            firstname: $scope.firstname,
            lastname: $scope.lastname
        };
		
		$http.post(url, data, config).then(function (response) {
			$scope.postResultMessage = response.data;
		}, function error(response) {
			$scope.postResultMessage = "Error with status: " +  response.statusText;
		});
		
		$scope.firstname = "";
		$scope.lastname = "";
	}
});

app.controller('getcontroller', function($scope, $http, $location) {
	$scope.getfunction = function(){
		var url = $location.absUrl() + "getallcustomer";
		
		$http.get(url).then(function (response) {
			$scope.response = response.data
		}, function error(response) {
			$scope.postResultMessage = "Error with status: " +  response.statusText;
		});
	}
});
7. Run & Check result

Run Spring Boot Application and check result:
http angularjs spring boot result

    1. Hi,

      You can do an http DELETE via an URL /customer/delete/{id} and AngularJs’s $http.delete function.

      In the Spring’s Controller, You need implement a new request mapping with annotation @DeleteMapping:

      @DeleteMapping("/customer/delete/{id}")
public String deleteMethod(@PathVariable int id) {
	// to do
	return "OK";
}

      Regards,

      Reply

      1. Thank you!
        Although I still have some problems, could you help me out?
        I think something is still wrong with passing the path variable, i keep getting deleteResultMessage=”Failed”
        Here is my code:

        HTML:

               
            Which client do you want to delete? (id)
            
            Remove
            {{deleteResultMessage}}

        CONTROLLER.JS

        app.controller('deleteController', function($scope, $http, $location) {
    $scope.submitForm = function(){
        var config = {
            headers : {
                'Content-Type': 'application/json;charset=utf-8;'}}
        var data = {
            id: $scope.id
        };

        var url = $location.absUrl() + "delete" + id;

        $http.delete(url, data, config).then(function (response) {
            $scope.deleteResultMessage = "Success";
        }, function (response) {
            $scope.deleteResultMessage = "Failed";
        });
        $scope.id = null;
    }
});

        and RestWebCotroller:

        @DeleteMapping("/delete/{id}")
    public String delete(@PathVariable Long id) {
        clientService.delete(id);
        return "OK";
    }
        Reply

          1. Ahhhhh, once i post the comment =my html code changes. Last attempt, of course in the programm i have “”:

            div ng-controller="deleteController"
        form   name="clientForm" ng-submit="submitForm()"
           label   Which client do you want to delete? (id)      /label
           input     type="number" name="id" class="form-control" ng-model="id"   
           button    type="submit" class="btn btn-danger custom-width"Remove   /button
           p   {{deleteResultMessage}}   /p
       /form>

          2. Hi,

            1. Firstly, please check again your url request:
            -> Your URL: var url = $location.absUrl() + "delete" + id;
            Correct is: var url = $location.absUrl() + "delete/" + id;

            2. Second:

            Default AngularJS with headers: 'Accept': 'application/json'
            Your controller returns a String format.

            -> Your’s Problem

            Solution:

            var config = {
                headers : {
                    'Accept': 'text/plain'
                }
        }
		
$http.delete(url, config)

    1. Hi,

      You can open a Eclipse Terminal by right click on the project -> Show in Local Terminal -> Terminal or Ctrl + Alt + T

      Then use the command-lines to build and run Spring Boot project: {mvn clean install, mvn spring-boot:run}

  5. Hi,

    I also try to implement the remember-me feature with angular js and spring boot but i didn’t succeded: this is the first part of my back end my SecurityConfigWeb.java:

    http.authorizeRequests()
        .antMatchers("/sentEmail", "/contactUs", "/reset", Constants.PATTERN1,Constants.PATHPATTERN2, Constants.PATHPATTERN3).permitAll()
        .anyRequest().authenticated().and()

            .and()
            .csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());

    1. Hello Vincent,

      You can follow the guide steps as below:

      1. Create AngularJs Controller for login, logout functions:

      // Config XMLHttpRequest to avoid pop-up alert with the default header 'WWW-Authenticate: Basic'.
app.config([ '$httpProvider', function($httpProvider) {
	$httpProvider.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
} ]);

// Controller
app.controller('AppCtrl', function($http, $scope) {
	
	// login function
	$scope.login = function() {
		// base64 encoded from username & password
		var base64Credential = btoa($scope.username + ':' + $scope.password);
		
		// GET request for user details
		$http.get('user', {
			headers : {
				// Authorization Header
				'Authorization' : 'Basic ' + base64Credential
			}
		}).success(function(result) {
			if (result.authenticated) {
				$scope.msg = '';
				$scope.userDetails = result;
			} else {
				$scope.msg = 'Authetication Failed !';
			}
			$scope.password = null;
		}).error(function(error) {
			$scope.msg = 'Authetication Failed !';
		});
	};
	
	// logout 
	$scope.logout = function() {
		// clear authorization header
		$http.defaults.headers.common['Authorization'] = null;
		// clear data
		$scope.userDetails = null;
		$scope.msg = 'Successfully logged out';
	};
	
	$scope.logout = function() {
	  $http.post('logout', {}).success(function() {
		$scope.userDetails = null;
		$location.path("/");
	  }).error(function(data) {
		$scope.userDetails;
	  });
	}

      2. Create a GET RestAPI for userInfo

      	
	@RequestMapping("/user")
	public Principal sayHello(Principal principal) {
		return principal;
	}

      Regards,
      JSA

      1. I do that this is my loginController:

        function loginController($scope,toastr, loginService,UsersService, $state,$http) {
	/*
	 * 
	 * login user after verifying the login service
	 * */
	 $scope.loginerror = false ;
	$scope.n=0;
	$scope.login = function() {
		$scope.n=$scope.n;
		loginService.login($scope.account).then(function(data) {	
		
			$scope.uiRouterState = $state;
			
			$state.go("dashboard");
		}, function(data) {

		
		  //  $scope.loginerror = function(data) {
			$scope.error = data.data["AuthenticationErrorMessage"];
			
			$scope.n=$scope.n+1;
			console.log("n: ", $scope.n);
		});

	};

and my loginService.js:

function loginService($http, $base64, $state) {
	var session = {};
	session.login = function(data) {
		return $http.post(_contextPath + '/',
				"username=" + data.username + "&password=" + data.password, {
					headers : {
						'Content-Type' : 'application/x-www-form-urlencoded'
					}
				}).success(function(response) {
			return response.status;
		}).error(function(response) {
			return response.status;
		})
	};

	session.logout = function() {
		$http.post(_contextPath + '/logout', {}).success(function(data) {
			$state.go("login");
		}).error(function(data) {
			alert("error" + data);
		});
	}

	session.getUser = function() {
		$http.get(_contextPath + "/getUser").success(function(data) {
			if (data.userLogin) {
				session.User = data.userLogin;	
			}else{
				$state.go("login");
			}
		}).error(function() {
		});
	}

	return session;
};

        This is my login.jsp for remember-me:
        Stay Logged In, my problem is my remember-me feature , i don’t succeeded to do it ,could you help me

        Thanks.

  6. Hi, I’m new in AngularJS and Spring. Can you help me to understand why I get customer null in postcustomer method?
    I tried to change the method input to String:

    @RequestMapping(value=”/postcustomer”, method=RequestMethod.POST)
    public String postCustomer(@RequestBody String customer){
    System.out.println(customer);
    //cust.add(customer);

    return “Sucessful!”;
    }

    and the output is correct:

    {“firstname”:”dfgdg”,”lastname”:”dfdfg”}

    What is going wrong?
