我决定单独的逻辑从RoleAppService到RoleService，因为我需要使用其他应用程序服务方面的作用的方法。通过分离逻辑我能避免喷射端点其它端点（例如RoleAppService到UserAppService）和可能的循环依赖关系。 API也看不到外面 - 这就是为什么从AbpServiceBase类继承，没有ApplicationService（这使得服务于招摇可见）。不幸的是，当我尝试使用RoleService方法内的样板管理类（如RoleManager，的UserManager），以下异常被抛出：
Cannot access a disposed object.
Object name: 'RoleManagerProxy'.

错误似乎与框架结构有关。我试图结束服务名AppService服务，但它并没有帮助的。服务是注册在温莎城堡的框架。什么有趣的 - 课内正常工作的样板库，像RoleRepository，UserReposistory - 不幸的是RoleManager /没有的UserManager。下面是类的片段：
public class RoleService : AbpServiceBase, IRoleService
{
private readonly RoleManager _roleManager;
private readonly IRepository<Role> _roleRepository;
private readonly UserManager _userManager;
private readonly IRepository<User, long> _userRepository;
private readonly IPermissionManager _permissionManager;
public RoleService(RoleManager roleManager, IRepository<Role> roleRepository,
UserManager userManager, IRepository<User, long> userRepository,
IPermissionManager permissionManager)
{
_roleManager = roleManager;
_roleRepository = roleRepository;
_userManager = userManager;
_userRepository = userRepository;
_permissionManager = permissionManager;
}
public async Task<RoleDto> Create(CreateRoleDto createRoleDto, Action<IdentityResult> checkErrorsMethod)
{
var role = ObjectMapper.Map<Role>(createRoleDto);
role.SetNormalizedName();
await _roleManager.UpdateAsync(role); // here exception is thrown
var grantedPermissions = _permissionManager
.GetAllPermissions()
.Where(p => createRoleDto.Permissions.Contains(p.Name))
.ToList();
await _roleManager.SetGrantedPermissionsAsync(role, grantedPermissions);
return role.MapTo<RoleDto>();
}
我将是任何帮助非常感激。
如果添加[UnitOfWork]属性，不要忘了做方法public virtual
