1. Todo Service

package com.cloudsole.angular.service;

import java.util.List;

/**
 * Created by tmichels on 8/1/14.
 */
public interface TodoService {
    public List<String> allTodos();
    public void addTodo(String todo);
    public void deleteTodo(String todo);
    public void deleteAll();
    public void updateTodo(int position, String todo);
}

2. Todo Service Implementation

package com.cloudsole.angular.service;

import org.springframework.stereotype.Service;

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

/**
 * Created by tmichels on 8/1/14.
 */

@Service
public class TodoServiceImpl implements TodoService {

    List<String> todos = new ArrayList<String>();

    @Override
    public List<String> allTodos() {
        return todos;
    }

    @Override
    public void addTodo(String todo) {
        todos.add(todo);
    }

    @Override
    public void deleteTodo(String todo) {
        if (todos.contains(todo)){
            todos.remove(todo);
        }
    }

    @Override
    public void deleteAll() {
        todos.clear();
    }


    @Override
    public void updateTodo(int position, String todo) {
        todos.set(position, todo);
    }
}

3. Todo Spring MVC Controller

package com.cloudsole.angular.controller;

import com.cloudsole.angular.service.TodoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

/**
 * Created by tmichels on 8/1/14.
 */

@Controller
@RequestMapping("/todo")
public class TodoController {

    @Autowired
    private TodoService todoService;

    @RequestMapping(value = "/all.json")
    public @ResponseBody List<String> viewAllTodos(){
        return todoService.allTodos();
    }

    @RequestMapping(value = "/add/{todo}", method = RequestMethod.POST)
    public @ResponseBody void addTodo(@PathVariable("todo") String todo){
        todoService.addTodo(todo);
    }

    @RequestMapping(value = "/delete/{todo}", method = RequestMethod.DELETE)
    public @ResponseBody void deleteTodo(@PathVariable("todo") String todo){
        todoService.deleteTodo(todo);
    }

    @RequestMapping(value = "/deleteAll", method = RequestMethod.DELETE)
    public @ResponseBody void deleteAllTodo(){
        todoService.deleteAll();
    }

    @RequestMapping(value="/update/{position}/{todo}", method = RequestMethod.PUT)
    public @ResponseBody void updateTodo(@PathVariable("position") String position, @PathVariable("todo") String todo){
        todoService.updateTodo(Integer.valueOf(position), todo);
    }

    @RequestMapping("/layout")
    public String getTodoPartialPage() {
        return "todo/layout";
    }
}

4. Angular App.js

'use strict';

var AngularSpringApp = {};

var App = angular.module('AngularSpringApp', ['AngularSpringApp.filters', 'AngularSpringApp.services', 'AngularSpringApp.directives', 'ngRoute', 'ui.bootstrap', 'ngTable', 'ui.ace', 'angularFileUpload']);

// Declare app level module which depends on filters, and services
App.config(['$routeProvider', function ($routeProvider) {

    $routeProvider.when('/todo', {
        templateUrl: 'todo/layout',
        controller: TodoController
    });
    $routeProvider.when('/address', {
        templateUrl: 'address/layout',
        controller: AddressBookController
    });
    $routeProvider.when('/table', {
        templateUrl: 'table/layout',
        controller: TableController
    });
    $routeProvider.when('/file', {
        templateUrl: 'file/layout',
        controller: FileController
    });
    $routeProvider.when('/editor', {
        templateUrl: 'editor/layout',
        controller: EditorController
    });
    $routeProvider.when('/rest', {
        templateUrl: 'restangular/layout',
        controller: RestController
    });
    $routeProvider.when('/force', {
        templateUrl: 'force/layout',
        controller: ForceController
    });

    $routeProvider.otherwise({redirectTo: '/todo'});
}]);

5. Angular TodoController


var TodoController = function($scope, $http){

    $scope.editMode = false;
    $scope.position = '';

    $scope.getAllTodos = function(){
        $scope.resetError();
        $http.get('todo/all.json').success(function(response){
            $scope.todos = response;
        }).error(function() {
            $scope.setError('Could not display all todos');
        });
    }

    $scope.addTodo = function(newTodo){
        $scope.resetError();
        $http.post('todo/add/' + newTodo).success(function(response){
            $scope.getAllTodos();
        }).error(function() {
            $scope.setError('Could add todo');
        });
        $scope.todoName = '';
    }

    $scope.deleteTodo = function(deleteTodo){
        $scope.resetError();
        $http.delete('todo/delete/'+deleteTodo).success(function(response){
            $scope.getAllTodos();
        }).error(function() {
            $scope.setError('Could not delete todo');
        });
    }

    $scope.deleteAllTodo = function(){
        $scope.resetError();
        $http.delete('todo/deleteAll').success(function(response){
            $scope.getAllTodos();
        }).error(function() {
            $scope.setError('Could not delete all todos');
        })
    }

    $scope.editTodo = function(position, todo){
        $scope.resetError();
        $scope.todoName = todo;
        $scope.position = position;
        $scope.editMode = true;
    }

    $scope.updateTodo = function(updateTodo){
        $scope.resetError();
        $http.put('todo/update/'+ $scope.position +'/'+updateTodo).success(function(response){
            $scope.getAllTodos();
            $scope.position = '';
            $scope.todoName = '';
            $scope.editMode = false;
        }).error(function(){
            $scope.setError('Could not update todo');
         })
    }

    $scope.resetTodoField = function() {
        $scope.resetError();
        $scope.todoName = '';
        $scope.editMode = false;
    };

    $scope.resetError = function() {
        $scope.error = false;
        $scope.errorMessage = '';
    };

    $scope.setError = function(message) {
        $scope.error = true;
        $scope.errorMessage = message;
    };

    $scope.getAllTodos();
}
