Swagger“规范中没有定义任何操作！”通用基础控制器问题

Question

我有一个接口，

IItemController<T>

，应用于基础

ItemController<T>

，它也继承了

ControllerBase

.

public class ItemController<T> : ControllerBase, IItemController<T> where T : class {
    private readonly IManager<T> _manager;
    private readonly ILogger<ItemController<T>> _logger;

    public ItemController(ILogger<ItemController<T>> logger, IManager<T> manager)
    {
        _logger = logger;
        _manager = manager;
    }

    [HttpGet($@"test")]
    public IActionResult Test(){
        return NoContent();
    }

    /* Other Methods */
}

然后我有一个

ProductController<T>

继承

ItemController<T>

指定

Product

类型：

[ApiController]
[Route("[controller]")]
public class ProductController<T> : ItemController<T> where T : Product
{
    private readonly IManager<T> _manager;
    private readonly ILogger<ProductController<T>> _logger;

    public ProductController(ILogger<ProductController<T>> logger, IManager<T> manager) : base(logger, manager)
    {
        _logger = logger;
        _manager = manager;
    }
}

我假设这应该为我继承

ItemController

的每个控制器生成招摇，但我得到：

“规范中没有定义任何操作！”

我尝试直接导航到 Urls，但它们似乎也不起作用，所以我可能遇到了一个不自大的问题。

这是我的 Program.cs

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();

// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddEntityFrameworkSqlite().AddDbContext<DataContext>(opt =>
    opt.UseSqlite(builder.Configuration.GetConnectionString("SqliteConnection")));

builder.Services.AddTransient(typeof(IManager<>), typeof(Manager<>));
builder.Services.AddTransient(typeof(IPager<>), typeof(Pager<>));
builder.Services.AddTransient(typeof(IRepository<>), typeof(Repository<>));
builder.Services.AddTransient(typeof(IItemController<>), typeof(ItemController<>));

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();
app.MapControllers();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints => endpoints.MapControllers());

app.Run();

Answer 1

我实际上简化了一点。我保持

ItemController

和

Program.cs

不变，并像这样更改了

ProductController

类：

[ApiController]
[Route("[controller]")]
public class ProductController : ItemController<Product>
{
    public ProductController(ILogger<ProductController> logger, IManager<Product> manager) : base(logger, manager)
    {
    }
}

我不确定为什么另一种方法不起作用，但无论如何这更简洁。
