搭建自己的框架WedeNet（四）
WedeNet2018.Web-UI层：
结构如下：
首先，在Controller中定义BaseController，以便加入统一处理逻辑，如下：
using log4net;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WedeNet2018.Common;
namespace WedeNet2018.Web.Controllers
{
/// <summary>
/// 控制器基类
/// </summary>
public class BaseController : Controller
{
protected ILog log { get; set; }
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
base.OnActionExecuting(filterContext);
log.Info("---进入BaseController---");
}
}
}
在这里我们也声明了log4net变量，可在其派生类中决定使用哪一种配置的log。
以默认控制器为例：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WedeNet2018.BussinessLogic;
using PagedList;
using WedeNet2018.Infrastructure;
using System.Text.RegularExpressions;
using WedeNet2018.Common;
using WedeNet2018.Common.Models;
using log4net;
namespace WedeNet2018.Web.Controllers
{
public class HomeController : BaseController
{
private OrdersBussinessLogic orderBll;
private ElongOrdersDetailsBussinessLogic elongBll;
private EmployeesBussinessLogic employeeBll;
public HomeController(OrdersBussinessLogic BLL, ElongOrdersDetailsBussinessLogic ElongBll, EmployeesBussinessLogic EmployeeBll)
{
log = LoggerHelper.WedeNetLogger;
orderBll = BLL;
elongBll = ElongBll;
employeeBll = EmployeeBll;
log.Info("----HomeController初始化完成。----");
}
public ActionResult Index(int? page)
{
log.InfoFormat("初始化首页数据，page={0}", page);
int pageSize = 10;
int pageNum = (page ?? 1);
var orders = orderBll.GetOrders(46).OrderBy(o => o.Id);
return View(orders.ToPagedList(pageNum,pageSize));
}
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(Orders order)
{
if (string.IsNullOrEmpty(order.OrderSn))
{
ModelState.AddModelError("OrderSn", "OrderSn不能为空");
}
if (order.UserId<0)
{
ModelState.AddModelError("UserId", "UserId必须大于0");
}
if (string.IsNullOrEmpty(order.UserName))
{
ModelState.AddModelError("UserName", "UserName不能为空");
}
if (string.IsNullOrEmpty(order.UserMobile))
{
ModelState.AddModelError("UserMobile", "UserMobile不能为空");
}
if (string.IsNullOrEmpty(order.Email))
{
ModelState.AddModelError("Email", "Email不能为空");
}
else
{
if (!ModelState.IsValidField(order.Email) || !new Regex(@"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*", RegexOptions.IgnoreCase).IsMatch(order.Email))
{
ModelState.AddModelError("Email", "Email不是正确的格式");
}
}
if (ModelState.IsValid)
{
order.MerchantId = 46;
order.UserMobile = "18210928340";
order.DeliveryTypeId = 0;
order.ServiceCost = 0;
order.DeliveryCost = 0;
order.PayCardType = 0;
order.Enabled = true;
order.IsSettledUp = true;
order.HasRecievePay = true;
order.HaveGetRecievePay = true;
order.Created = DateTime.Now;
order.LastModified = DateTime.Now;
order.PaySn = "";
order.OrderType = 46;
order.Satisfaction = 0;
orderBll.Add(order);
//插入ElongOrdersDetails表
ElongOrdersDetails detail = new ElongOrdersDetails();
detail.OrderGuid = Guid.NewGuid();
detail.OrderSn = order.OrderSn;
detail.OrderId = 0;
detail.Status = order.Status;
detail.Created = DateTime.Now;
detail.LastModified = DateTime.Now;
elongBll.Add(detail);
orderBll.Commit();
return RedirectToAction("Index");
}
return View();
}
public ActionResult Details(int id)
{
Orders order = orderBll.Find(id);
return View(order);
}
public ActionResult Edit(int id)
{
Orders order = orderBll.Find(id);
return View(order);
}
[HttpPost]
public ActionResult Edit(Orders orderEdit)
{
Orders order = orderBll.Find(orderEdit.Id);
if (string.IsNullOrEmpty(orderEdit.Email))
{
ModelState.AddModelError("Email", "Email不能为空");
}
else
{
if (!ModelState.IsValidField(orderEdit.Email) || !new Regex(@"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*", RegexOptions.IgnoreCase).IsMatch(orderEdit.Email))
{
ModelState.AddModelError("Email", "Email不是正确的格式");
}
}
if (ModelState.IsValid) {
order.Email = orderEdit.Email;
order.Status = orderEdit.Status;
order.ServiceCost = orderEdit.ServiceCost;
orderBll.Update(order);
}
return RedirectToAction("Index");
}
public ActionResult Delete(int id)
{
orderBll.Delete(id);
return RedirectToAction("Index");
}
public JsonResult GetEmployees() {
ResponseBase<List<Employees>> result = new ResponseBase<List<Employees>>();
try
{
var employees = employeeBll.GetAll().ToList();
result.IsSuccess = true;
result.Message = "查询成功！";
result.resultCode = "200";
result.ResultData = employees;
}
catch (Exception ex) {
result.IsSuccess = false;
result.Message = "查询异常！"+ex.Message;
result.resultCode = "500";
}
return Json(result);
}
}
}
注意到了，我在构造函数中进行了一些初始化，有日志的，有需要用到的BussinessLogic处理类，这些BussinessLogic处理类是依赖NInject注入实例化的，而且这三个处理类是属于不同的UnitOfWork和dbcontext（OrdersBussinessLogic和ElongOrdersDetailsBussinessLogic属于IWedeUnitOfWorks，而EmployeesBussinessLogic属于IXF0816UnitOfWorks）。
这里要说一下日志，在这个控制器中我把基类的日志初始化为WedeNetLogger，其实要分类打印的日志可以有很多，如：
根据需要对日志进行分类，并且在控制器的构造函数中根据情况进行初始化。
Ninject映射
要配置NInject，就需要先实现一个工厂，如：
using Ninject;
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using WedeNet2018.BussinessLogic;
using WedeNet2018.Infrastructure;
using WedeNet2018.Infrastructure.Components;
namespace WedeNet2018.Web.Controllers
{
/// <summary>
/// Ninject工厂类
/// </summary>
public class NinjectControllerFactory : DefaultControllerFactory
{
private IKernel ninjectKernel;
public NinjectControllerFactory()
{
ninjectKernel = new StandardKernel();
AddBindings();
}
private void AddBindings()
{
ninjectKernel.Bind<AbsWedeDBContex>().To<WedeDBContex>();
ninjectKernel.Bind<IWedeUnitOfWorks>().To<WedeUnitOfWorks<AbsWedeDBContex>>().InSingletonScope();
ninjectKernel.Bind<OrdersBussinessLogic>().ToSelf();
ninjectKernel.Bind<ElongOrdersDetailsBussinessLogic>().ToSelf();
ninjectKernel.Bind<AbsXF0816DBContex>().To<XF0816DBContex>();
ninjectKernel.Bind<IXF0816UnitOfWorks>().To<XF0816UnitOfWorks<AbsXF0816DBContex>>().InSingletonScope();
ninjectKernel.Bind<EmployeesBussinessLogic>().ToSelf();
}
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
return controllerType == null ? null : (IController)ninjectKernel.Get(controllerType);
}
}
}
我在工厂类的AddBindings()方法里进行了各种映射关系配置。
实现了工厂以后，还需要在Global.asax中注册这个工厂类，如：
然后，我们就可以使用NInject了。
MVC4的Bundles
UI项目里往往需要加载很多js和css，一些通用的可以放在Bundles里让MVC帮忙，如：
bundles.Add(new ScriptBundle("~/bundles/jss").Include(
"~/Scripts/jquery-{version}.js",
"~/Bootstrap/js/bootstrap.js",
"~/js/common.js",
"~/js/layer/layer.js"
));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/site.css",
"~/Bootstrap/css/bootstrap.css",
"~/Bootstrap/css/bootstrap-grid.css",
"~/Bootstrap/css/bootstrap-reboot.css",
"~/js/layer/skin/layer.css",
"~/js/layer/skin/default/layer.css"
));
然后，就可以在视图模板中使用了，如：
UI展示层主要说明的就这些，另外Bootstrap、layer、jQuery、H5+CSS3内容不介绍了。
