for example, I have an IAbcAppService and AppService class, but how can I call it in my controller? I don't know how to instantiate it
in my app service:
public class ABCAppService: IABCAppService
{
private readonly IRepository<ABCModel> _abcRepository;
public ABCAppService(IRepository<ABCModel> abcRepository)
{
_abcRepository = abcRepository;
}
}
and in my controller:
public class ABCController : ABCControllerBase
{
private readonly IABCAppService _abcAppService;
public ABCController()
{
//should I use this way? but it doesn't work :(
_abcAppService = IocManager.Instance.Resolve<IABCAppService>();
}
}
just don't know how to init the _abcAppService in controller.

Just inject your application service into controller as you did it for repository.
Note1: Your IABCAppService should inherit from IApplicationService. Note2: Do not resolve it from IocManager.Instance since it may cause to memory leaks. I suggest you to read DI document to fully understand it: <a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Dependency-Injection">http://www.aspnetboilerplate.com/Pages/ ... -Injection</a>

yes, actually I tried everything before, but still not working, but when I reset the DB and run update-database again, that's working, maybe I use the difference table name between entity and database, but suppose that's not be an issue, I have set the table attribute in the entity model

Hi,
Do you still have this error ? Can you share your logs and final code of service and controller ?

Yes, that strange, when I create a new table and controller, I got the error again, don't know why :(
I got the below errors:
Server Error in '/' Application. Can't create component 'MPeLife.FormLayoutApp.FormLayoutAppService' as it has dependencies to be satisfied. 'MPeLife.FormLayoutApp.FormLayoutAppService' is waiting for the following dependencies: - Service 'Abp.Domain.Repositories.IRepository`1[[MPeLife.Models.FormLayout, MPeLife.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' which was not registered.
in my controller:
private readonly IFormLayoutAppService _formLayoutAppService; public FormLayoutController(IFormLayoutAppService formLayoutAppService) { _formLayoutAppService = formLayoutAppService; }
in app service:
private readonly IRepository<FormLayout> _formLayoutRepository; public FormLayoutAppService(IRepository<FormLayout> formLayoutRepository) { _formLayoutRepository = formLayoutRepository; }
I didn't change any things, just create the new table:(

I found that if I use a repository to inject the app service, and it's working:
private readonly IFormLayoutRepository _formLayoutRepository; public FormLayoutAppService(IFormLayoutRepository formLayoutRepository) { _formLayoutRepository = formLayoutRepository; }
but why it must be use Repository? I have no other custom method to use, so if I create the Repository for each table, these Repositories are empty, and I have to create an interface and implements it, but I just want to use the simple generic methods:
IRepository<MyModel>

Hi,
It should work as you expected. Can you share your FormLayout entity definition ?

Yes, after I used the Repository and it's working, below is my entity, there is no any especially:
public class FormLayout : Entity, IModificationAudited, ICreationAudited { public virtual bool Active { get; set; } [Required] public virtual int CateTabId { get; set; } [Required] public virtual string Name { get; set; } [Required] public virtual string Value { get; set; } public DateTime CreationTime { get; set; } public DateTime? LastModificationTime { get; set; } public long? LastModifierUserId { get; set; } public long? CreatorUserId { get; set; } [ForeignKey("CreatorUserId")] public virtual AdminUser CreatorUser { get; set; } [ForeignKey("LastModifierUserId")] public virtual AdminUser LastModifierUser { get; set; } [ForeignKey("CateTabId")] public virtual CategoryTab CateTab { get; set; } }
