ABP 依赖注入不了 Can't create component 'xxx.xxx.xxx' as it has dependencies to be satisfied

报错：

An unhandled exception occurred while processing the request.
HandlerException: Can't create component 'BIMMP.OAMS.OAContractSealAppService' as it has dependencies to be satisfied.

'BIMMP.OAMS.OAContractSealAppService' is waiting for the following dependencies:
- Service 'Abp.Domain.Repositories.IRepository`2[[BIMMP.OAMS.OAContractSeal, BIMMP.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[System.Int32, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]' which was not registered.
Castle.MicroKernel.Handlers.DefaultHandler.AssertNotWaitingForDependency()

原因：

BIMMPDbContext 中忘了加这句 public virtual DbSet<OAContractSeal> OAContractSeals { get; set; }

总结：

数据库里面也有那张表，估计是谁提交代码的时候，把那句代码给冲掉了

全部代码：

IOAContractSealAppService.cs

namespace BIMMP.OAMS
{
    public interface IOAContractSealAppService : IApplicationService
    {
       
    }
}

OAContractSealAppService.cs

namespace BIMMP.OAMS
{
    [AbpAuthorize]
    public class OAContractSealAppService : BIMMPAppServiceBase, IOAContractSealAppService
    {
        private readonly IRepository<OAContractSeal, int> _oAContractSealRepository;

        public OAContractSealAppService(
        IRepository<OAContractSeal, int> oAContractSealRepository)
        {
            _oAContractSealRepository = oAContractSealRepository;
        }
    }
}

BIMMPDbContext.cs

namespace BIMMP.EntityFrameworkCore
{
    public class BIMMPDbContext : AbpZeroDbContext<Tenant, Role, User, BIMMPDbContext>
    {
        public virtual DbSet<OAContractSeal> OAContractSeals { get; set; }
        public BIMMPDbContext(DbContextOptions<BIMMPDbContext> options)
            : base(options)
        {
        }
    }
}

OAContractSeal.cs

namespace BIMMP.OAMS
{
    [Table("OAContractSeal")]
    public class OAContractSeal : AuditedEntity<int>
    {
        [Required]
        [MaxLength(50)]
        public string ContractName { get; set; }
    }
}
