ABP学习入门系列（五）（展示实现增删改查）

大致要实现的 效果如下

1，添加Controller（用到的X.PagedList 注意到nuget添加）

using System.Web.Mvc;
using Abp.Application.Services.Dto;
using Abp.Runtime.Caching;
using Abp.Threading;
using Abp.Web.Mvc.Authorization;
using AutoMapper;
using LearningMpaAbp.Notifications;
using LearningMpaAbp.Tasks;
using LearningMpaAbp.Tasks.Dtos;
using LearningMpaAbp.Users;
using LearningMpaAbp.Users.Dto;
using LearningMpaAbp.Web.Models.Tasks;
using X.PagedList;

namespace LearningMpaAbp.Web.Controllers
{
    [AbpMvcAuthorize]
    public class TasksController : LearningMpaAbpControllerBase
    {
        private readonly ITaskAppService _taskAppService;
        private readonly IUserAppService _userAppService;
        private readonly INotificationAppService _notificationAppService;
        private readonly ICacheManager _cacheManager;

        public TasksController(ITaskAppService taskAppService, IUserAppService userAppService, ICacheManager cacheManager, INotificationAppService notificationAppService)
        {
            _taskAppService = taskAppService;
            _userAppService = userAppService;
            _cacheManager = cacheManager;
            _notificationAppService = notificationAppService;
        }

        public ActionResult Index(GetTasksInput input)
        {
            var output = _taskAppService.GetTasks(input);

            var model = new IndexViewModel(output.Tasks)
            {
                SelectedTaskState = input.State
            };
            return View(model);
        }

        // GET: Tasks
        public ActionResult PagedList(int? page)
        {
            //每页行数
            var pageSize = 5;
            var pageNumber = page ?? 1; //第几页

            var filter = new GetTasksInput
            {
                SkipCount = (pageNumber - 1) * pageSize, //忽略个数
                MaxResultCount = pageSize
            };
            var result = _taskAppService.GetPagedTasks(filter);

            //已经在应用服务层手动完成了分页逻辑，所以需手动构造分页结果
            var onePageOfTasks = new StaticPagedList<TaskDto>(result.Items, pageNumber, pageSize, result.TotalCount);
            //将分页结果放入ViewBag供View使用
            ViewBag.OnePageOfTasks = onePageOfTasks;

            return View();
        }


        public PartialViewResult GetList(GetTasksInput input)
        {
            var output = _taskAppService.GetTasks(input);
            return PartialView("_List", output.Tasks);
        }

        /// <summary>
        /// 获取创建任务分部视图
        /// 该方法使用ICacheManager进行缓存，在WebModule中配置缓存过期时间为10mins
        /// </summary>
        /// <returns></returns>
        public PartialViewResult RemoteCreate()
        {
            //1.1 注释该段代码，使用下面缓存的方式
            //var userList = _userAppService.GetUsers();

            //1.2 同步调用异步解决方案（最新Abp创建的模板项目已经去掉该同步方法，所以可以通过下面这种方式获取用户列表）
            //var userList = AsyncHelper.RunSync(() => _userAppService.GetUsersAsync());

            //1.3 缓存版本
            var userList = _cacheManager.GetCache("ControllerCache").Get("AllUsers", () => _userAppService.GetUsers());

            //1.4 转换为泛型版本
            //var userList = _cacheManager.GetCache("ControllerCache").AsTyped<string, ListResultDto<UserListDto>>().Get("AllUsers", () => _userAppService.GetUsers());

            //1.5 泛型缓存版本
            //var userList = _cacheManager.GetCache<string, ListResultDto<UserListDto>>("ControllerCache").Get("AllUsers", () => _userAppService.GetUsers());

            ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name");
            return PartialView("_CreateTaskPartial");
        }

        /// <summary>
        /// 获取创建任务分部视图（子视图）
        /// 该方法使用[OutputCache]进行缓存，缓存过期时间为2mins
        /// </summary>
        /// <returns></returns>
        [ChildActionOnly]
        [OutputCache(Duration = 1200, VaryByParam = "none")]
        public PartialViewResult Create()
        {
            var userList = _userAppService.GetUsers();
            ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name");
            return PartialView("_CreateTask");
        }

        // POST: Tasks/Create
        // 为了防止“过多发布”攻击，请启用要绑定到的特定属性，有关 
        // 详细信息，请参阅 http://go.microsoft.com/fwlink/?LinkId=317598。
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create(CreateTaskInput task)
        {
            var id = _taskAppService.CreateTask(task);

            var input = new GetTasksInput();
            var output = _taskAppService.GetTasks(input);

            return PartialView("_List", output.Tasks);
        }

        // GET: Tasks/Edit/5

        public PartialViewResult Edit(int id)
        {
            var task = _taskAppService.GetTaskById(id);

            var updateTaskDto = Mapper.Map<UpdateTaskInput>(task);

            var userList = _userAppService.GetUsers();
            ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name", updateTaskDto.AssignedPersonId);

            return PartialView("_EditTask", updateTaskDto);
        }

        // POST: Tasks/Edit/5
        // 为了防止“过多发布”攻击，请启用要绑定到的特定属性，有关 
        // 详细信息，请参阅 http://go.microsoft.com/fwlink/?LinkId=317598。
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit(UpdateTaskInput updateTaskDto)
        {
            _taskAppService.UpdateTask(updateTaskDto);

            var input = new GetTasksInput();
            var output = _taskAppService.GetTasks(input);

            return PartialView("_List", output.Tasks);
        }

        public ActionResult NotifyUser()
        {
            _notificationAppService.NotificationUsersWhoHaveOpenTask();
            return new EmptyResult();
        }
    }
}

2，视图

@using Abp.Web.Mvc.Extensions
@model LearningMpaAbp.Web.Models.Tasks.IndexViewModel

@{
    ViewBag.Title = L("TaskList");
    ViewBag.ActiveMenu = "TaskList"; //Matches with the menu name in SimpleTaskAppNavigationProvider to highlight the menu item
}
@section scripts{
    @Html.IncludeScript("~/Views/Tasks/index.js");
}
<h2>
    @L("TaskList")

    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#add">Create Task</button>

    <a class="btn btn-primary" data-toggle="modal" href="@Url.Action("RemoteCreate")" data-target="#modal" role="button">（Create Task）使用Remote方式调用Modal进行展现</a>

    <a class="btn btn-success" href="@Url.Action("PagedList")" role="button">分页展示</a>

    <button type="button" class="btn btn-info" onclick="notifyUser();">通知未完成任务的用户</button>
    <!--任务清单按照状态过滤的下拉框-->
    <span class="pull-right">
        @Html.DropDownListFor(
            model => model.SelectedTaskState,
            Model.GetTaskStateSelectListItems(),
            new
            {
                @class = "form-control select2",
                id = "TaskStateCombobox"
            })
    </span>
</h2>

<!--任务清单展示-->
<div class="row" id="taskList">
    @{ Html.RenderPartial("_List", Model.Tasks); }
</div>

<!--通过初始加载页面的时候提前将创建任务模态框加载进来-->
@Html.Action("Create")

<!--编辑任务模态框通过ajax动态填充到此div中-->
<div id="edit">

</div>

<!--Remote方式弹出创建任务模态框-->
<div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="createTask" data-backdrop="static">
    <div class="modal-dialog" role="document">
        <div class="modal-content">

        </div>
    </div>
</div>

另外还有_createTaskPartial，_EditTaskPartial 等，这里就不贴代码了

以上。。。
