  To map all exceptions of a specific type (such as BusinessException) to a particular HTTP status code (e.g., 422 Unprocessable Entity) in ABP Framework, you need to configure custom mappings in your application's startup. While the built-in Map method is for error codes, you can achieve type-based mapping by replacing the default status code finder service.

  Here's how you can do it:

  1. Create a custom implementation of DefaultHttpExceptionStatusCodeFinder:

  using System.Net;
  using Volo.Abp.AspNetCore.ExceptionHandling;
  using Volo.Abp.ExceptionHandling;
  
  public class CustomHttpExceptionStatusCodeFinder : DefaultHttpExceptionStatusCodeFinder
  {
      public override HttpStatusCode GetStatusCode(HttpExceptionStatusCodeContext context)
      {
          if (context.Exception is BusinessException)
          {
              return (HttpStatusCode)422; // Unprocessable Entity
          }
  
          return base.GetStatusCode(context);
      }
  }
  

  2. Register your custom finder in the dependency injection container (usually in your module's ConfigureServices method):

  using Microsoft.Extensions.DependencyInjection;
  using Volo.Abp.AspNetCore.ExceptionHandling;
  
  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      context.Services.AddTransient<IHttpExceptionStatusCodeFinder, CustomHttpExceptionStatusCodeFinder>();
  }
  

  This will ensure that all exceptions of type BusinessException are returned with HTTP status code 422.

  AI is right.

  You can override the DefaultHttpExceptionStatusCodeFinder.
