在查询递归实体查找时，我收到以下错误。

错误：

仅在添加具有ParentId

的第一个条目后才会出现错误

模型

     [Table("Categories")]
     public class Category : FullAuditedEntity
     {
        [Required]
        public string Name { get; set; }
        [Required]
        public string SharepointMapping { get; set; }
        public int? ParentId { get; set; }
        public Category Parent { get; set; }
       public List<Category> Children { get; set; }
     }

CategoryAppService

  public ListResultDto<CategoryListDto> GetCategories(GetCategoriesInput input)
  {
    var categories = _categoryRepository
        .GetAll()
        .WhereIf(
            !input.Filter.IsNullOrEmpty(),
            p => p.Name.Contains(input.Filter) 
        )
        .OrderBy(p => p.Name)
        .ToList();

        return new ListResultDto<CategoryListDto>(categories.MapTo<List<CategoryListDto>>());
  }

CategoryListDto

[AutoMapFrom(typeof(Category))]
public class CategoryListDto : FullAuditedEntityDto
{
    public string Name { get; set; }
    public string SharepointMapping { get; set; }
    public int? ParentId { get; set; }
    public virtual Category Parent { get; set; }       
}

所有WebApi方法的默认http-verb为 POST 。 使用POST发出请求。

如果你不喜欢这个解决方案，你可以使用传统的动词。使用常规谓词，它查找方法名称前缀并匹配相关的http-verb。

• GetCategories - ＆gt; HTTP-GET
• DeleteCategory - ＆gt; HTTP-DELETE
• UpdateCategory - ＆gt; HTTP-PUT
• CreateCategory - ＆gt; HTTP-POST

您可以使用WithConventionalVerbs方法，如下所示：

Configuration.Modules.AbpWebApi().DynamicApiControllerBuilder
    .ForAll<IApplicationService>(Assembly.GetAssembly(typeof(SimpleTaskSystemApplicationModule)), "tasksystem")
    .WithConventionalVerbs()
    .Build();
