asp.net mvc 通用控制器 [英] asp.net mvc generic controller

问题描述

我正在考虑在 ASP.NET MVC 中实现一个通用控制器.

I am thinking of implementing a generic Controller in ASP.NET MVC.

PlatformObjectController<T>

其中 T 是(生成的)平台对象.

where T is a (generated) platform object.

这可能吗?有经验/文档吗?

Is this possible? Is there experience / documentation?

例如，一个相关的问题是生成的 URL 是怎样的.

One related question for example is how the resulting URLs are.

推荐答案

是的，你不能直接使用它，但你可以继承它并使用孩子

yes it is, you just can't use it directly but you can inherit it and use the childs

这是我使用的一个:

     public class Cruder<TEntity, TInput> : Controller
        where TInput : new()
        where TEntity : new()
    {
        protected readonly IRepo<TEntity> repo;
        private readonly IBuilder<TEntity, TInput> builder;


        public Cruder(IRepo<TEntity> repo, IBuilder<TEntity, TInput> builder)
        {
            this.repo = repo;
            this.builder = builder;
        }

        public virtual ActionResult Index(int? page)
        {
            return View(repo.GetPageable(page ?? 1, 5));
        }

        public ActionResult Create()
        {
            return View(builder.BuildInput(new TEntity()));
        }

        [HttpPost]
        public ActionResult Create(TInput o)
        {
            if (!ModelState.IsValid)
                return View(o);
            repo.Insert(builder.BuilEntity(o));
            return RedirectToAction("index");
        }
    }

和用法:

 public class FieldController : Cruder<Field,FieldInput>
    {
        public FieldController(IRepo<Field> repo, IBuilder<Field, FieldInput> builder)
            : base(repo, builder)
        {
        }
    }

    public class MeasureController : Cruder<Measure, MeasureInput>
    {
        public MeasureController(IRepo<Measure> repo, IBuilder<Measure, MeasureInput> builder) : base(repo, builder)
        {
        }
    }

    public class DistrictController : Cruder<District, DistrictInput>
    {
        public DistrictController(IRepo<District> repo, IBuilder<District, DistrictInput> builder) : base(repo, builder)
        {
        }
    }

    public class PerfecterController : Cruder<Perfecter, PerfecterInput>
    {
        public PerfecterController(IRepo<Perfecter> repo, IBuilder<Perfecter, PerfecterInput> builder) : base(repo, builder)
        {
        }
    }
