为什么我得到了与URL匹配的多个控制器类型？

Question

我有一个叫Shopex的项目。

我改名为人力资源部

现在请求控制器

我得到以下错误

找到与URL匹配的多个控制器类型。如果多个控制器上的属性路由与请求的URL匹配，则可能发生这种情况。

请求找到了以下匹配的控制器类型: HR.Web.Controllers.EmployeeController Shopex.Web.Controllers.EmployeeController

我改变了

public static void ConfigureMvc(RouteCollection routes)
        {
            AreaRegistration.RegisterAllAreas();
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapMvcAttributeRoutes();
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Employee", action = "Index", id = UrlParameter.Optional },
                new[] { "HR.Web.Controllers" }
            );
        }

所以我添加了名字空间HR.Web.Controllers

现在，我需要在每个控制器类中作为一个属性来执行这个操作吗？

这是我的控制器

namespace HR.Web.Controllers
{
    [RoutePrefix("admin/employees")]
    public class EmployeeController : BaseController
    {
        private readonly IEmployeeService _employeeService;
        private readonly int _pageSize;

     
        public EmployeeController(IEmployeeService EmployeeService)
            : base()
        {
            _employeeService = EmployeeService;
            _pageSize = 10;
        }

        
        [Route("")]
        public async Task<ActionResult> Index(int pageIndex = 1, string q = "")
        {
            var employees = await GetEmployees(pageIndex, q, true);
            return View(employees);
        }

        [Route("unique")]
        public async Task<ActionResult> Unique(int pageIndex = 1, string q = "")
        {
            return Redirect("~/admin/Departments");

        }

        [Route("add")]
        public async Task<ActionResult> Add()
        {
            return View();
        }

        [Route("add")]
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Add(Employee employee)
        {
            await _employeeService.AddAsync(employee);
            return RedirectToAction("Index");
        }





        [Route("edit/{id:int:min(1)}")]
        public async Task<ActionResult> Edit(int id)
        {
            var employee = await _employeeService.GetByIdAsync(id);
            if (employee == null)
            {
                return RedirectToAction("Index");
            }
            return View(employee);
        }


        [Route("edit/{id:int:min(1)}")]
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Edit(Employee employee)
        {
            await _employeeService.UpdateAsync(employee);
            return RedirectToAction("Index");
        }





        [Route("delete/{id:int:min(1)}")]
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Delete(int id)
        {
            var isAuthorized = await _employeeService.Delete(id);
            return RedirectToAction("Index");
        }
        private async Task<IList<Employee>> GetEmployees(int pageIndex, string keyword, bool shared)
        {
            if (pageIndex < 1)
            {
                pageIndex = 1;
            }
            var list = await _employeeService.GetAllAsync(pageIndex, _pageSize, keyword, shared);
            return list;
        }
    }
}

Answer 1

按照错误的说法，

The request has found the following matching controller types: HR.Web.Controllers.EmployeeController Shopex.Web.Controllers.EmployeeController

这意味着您有多个EmployeeController。检查HR.Web.Controllers和Shopex.Web.Controllers中是否有多个控制器。如果不是，那么编译后的dll(选中bin文件夹)中可能有重复的控制器。
