我正在尝试使用Autofac autowired属性为控制器调用的自定义类设置类。我有一个设置测试项目来展示这一点。我的解决方案中有两个项目。 MVC Web应用程序和服务类库。下面的代码:Autofac不自动将属性自动接线到自定义类
在服务项目中,AccountService.cs:
public interface IAccountService
{
string DoAThing();
}
public class AccountService : IAccountService
{
public string DoAThing()
{
return "hello";
}
}
现在剩下的就是在MVC Web项目。
的Global.asax.cs
var builder = new ContainerBuilder();
builder.RegisterControllers(Assembly.GetExecutingAssembly()).PropertiesAutowired();
builder.RegisterAssemblyTypes(typeof(AccountService).Assembly)
.Where(t => t.Name.EndsWith("Service"))
.AsImplementedInterfaces().InstancePerRequest();
builder.RegisterType<Test>().PropertiesAutowired();
builder.RegisterFilterProvider();
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
test.cs中:
public class Test
{
//this is null when the var x = "" breakpoint is hit.
public IAccountService _accountService { get; set; }
public Test()
{
}
public void DoSomething()
{
var x = "";
}
}
HomeController.cs
public class HomeController : Controller
{
//this works fine
public IAccountService _accountServiceTest { get; set; }
//this also works fine
public IAccountService _accountService { get; set; }
public HomeController(IAccountService accountService)
{
_accountService = accountService;
}
public ActionResult Index()
{
var t = new Test();
t.DoSomething();
return View();
}
//...
}
正如你可以从上面的代码中看到,无论是_accountServiceTest
和_accountService
在控制器中正常工作,但在DoSomething()
方法中设置断点时Test.cs
,_accountService
始终为空,无论我放在中。
这很有道理。我测试了这些变化,并发挥了作用。我很感激帮助! –
