aspnetboilerplate - 同一方法中的多数据库

Question

我的应用程序有 2 个数据库，Db1（有表dbo.Student）和Db2（有表dbo.School）。我创建了 2 个 AppService 来访问它们当我尝试从它们两者中获取数据时，它只使用到（在当前上下文中Db1找不到表）的连接。dbo.School那么如何同时从 Db1 和 Db2 获取数据

private readonly IStudentAppService _studentAppService;
private readonly ISchoolAppService _schoolAppService;

public BranchAccountController(IStudentAppService studentAppService,
ISchoolAppService schoolAppService)
{
     _studentAppService = studentAppService;
     _schoolAppService = schoolAppService;
}

public async Task<PartialViewResult> GetStudent(int? id)
{           
     //Repository 1 (Database 1)
     var student = await _studentAppService.GetStudentForEdit(new NullableIdDto { Id = id });
     //Repository 2 (Database 2)
     var school = await _schoolAppService.GetSchoolList();

     //bla bla      
}

更新1：我试图在学生之前获得学校并面临以下错误：传入的交易与当前连接无关。只能使用与当前连接关联的事务。

您必须Begin分开工作单元：

public async Task<PartialViewResult> GetStudent(int? id)
{           
    List<SchoolDto> schools;
    StudentDto student;

    using (var uow = UnitOfWorkManager.Begin(TransactionScopeOption.Suppress))
    {
        // Repository 1 (Database 1)
        student = await _studentAppService.GetStudentForEdit(new NullableIdDto { Id = id });
        uow.Complete();
    }

    using (var uow = UnitOfWorkManager.Begin(TransactionScopeOption.Suppress))
    {
        // Repository 2 (Database 2)
        schools = await _schoolAppService.GetSchoolList();
        uow.Complete();
    }

    // ...
}
