我的global.asax如下所示
private void BuildIocContainer()
{
var builder = new ContainerBuilder();
builder.RegisterModule(new BootstrapModule());
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container); //Set the WebApi DependencyResolver
}
protected void Application_Start()
{
BuildIocContainer();
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
我为autofac构建了一个bootstrap模块,如下面的那个
public class BootstrapModule : Autofac.Module
{
private Assembly AssemblyOf<T>()
{
return typeof(T).Assembly;
}
private Assembly WebAssembly
{
get { return Assembly.GetExecutingAssembly(); }
}
private void RegisterMvc(ContainerBuilder builder)
{
builder.RegisterType<AsyncControllerActionInvoker>()
.As<IActionInvoker>();
builder.RegisterControllers(WebAssembly)
.InjectActionInvoker();
builder.RegisterApiControllers(WebAssembly).InjectActionInvoker();
}
private void RegisterLogger(ContainerBuilder builder)
{
builder.Register(CreateLogger)
.SingleInstance();
builder.Register(_ => new NLogWrapper(LogManager.GetLogger("DefaultLogger")))
.As<Logging.ILogger>()
.SingleInstance();
}
private static System.Func<Type, Logging.ILogger> CreateLogger(IComponentContext componentContext)
{
return type => new NLogWrapper(LogManager.GetLogger(type.FullName));
}
protected override void Load(ContainerBuilder builder)
{
RegisterLogger(builder);
RegisterMvc(builder);
builder.RegisterAssemblyTypes(WebAssembly)
.AsImplementedInterfaces();
builder.RegisterType<UserService>()
.As<IUserService>()
.InstancePerRequest();
builder.RegisterAssemblyTypes(typeof(IUserService).Assembly)
.AsImplementedInterfaces();
builder.RegisterAssemblyTypes(typeof(IUserRepository).Assembly)
.AsImplementedInterfaces();
builder.RegisterFilterProvider();
}
}
现在,当我尝试通过邮递员客户端点击帐户控制器时,
private IUserService _userService;
public AccountController(IUserService userService)
{
_userService = userService;
}
// POST api/Account/Register
[AllowAnonymous]
[Route("Register")]
public HttpStatusCode Register(User model)
{
if (!ModelState.IsValid)
{
return HttpStatusCode.BadRequest;
}
// TODO : Write mapper if needed
var user = new ToolUser()
{
FirstName = model.FirstName,
LastName = model.LastName,
EmailID = model.EmailID,
DOB = Convert.ToDateTime(model.DateOfBirth),
Gender = model.Gender.ToString(),
TenandID = model.TenantID,
Password = model.Password
};
HttpStatusCode result = _userService.RegisterUser(user);
return result;
}
我收到错误
“尝试创建'AccountController'类型的控制器时发生错误。确保控制器具有无参数的公共构造函数。”
我做错了什么?
答案 0 :(得分:3)
你应该有类似的东西
HttpConfiguration config = new HttpConfiguration();
某处,你用它来注册你的路线等。
将该配置传递给BuildIocContainer()
mehod并添加行
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
而不是
GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container); //Set the WebApi DependencyResolver
希望有所帮助
