ASPNET样板,扩展审计日志
我正在尝试扩展ASPNETBOILETPLATE框架中的AuditLog实体,以便为其添加一些新属性。我试图扩展类(),并实现自定义版本的类()。但是,我无法在构造函数中注入我的 new并收到两条关于and方法中不匹配输入参数的错误消息。AuditLogExtendedAuditInfoAuditStoreExtendedAuditStoreExtendedAuditInfoConstructorSaveAsync
类ExtendedAuditInfo:
public class ExtendedAuditInfo : AuditInfo
{
// Some properties
}
类ExtendedAuditStore:
public class ExtendedAuditStore : AuditingStore
{
public ExtendedAuditStore(IRepository<ExtendedAuditInfo, long> auditLogRepository)
: base(auditLogRepository)
{
}
public override Task SaveAsync(ExtendedAuditInfo auditInfo)
{
if (!string.IsNullOrEmpty(auditInfo.Parameters) && auditInfo.Parameters != "{}")
{
var parameters = JsonConvert.DeserializeObject<AuditParameterInput>(auditInfo.Parameters);
if (parameters != null)
auditInfo.CustomData = parameters.Input.Id.ToString();
}
return base.SaveAsync(auditInfo);
}
}
错误是:
无法从“Abp.Domain.Repositories.IRepository<SixB.Serafina.Auditing.ExtendedAuditInfo, long>”转换为“Abp.Domain.Repositories.IRepository<Abp.Auditing.AuditLog, long>”
和
找不到合适的方法来覆盖
上面的过程是基于我在这里找到的想法

我根据官方文档How To Extend Existing Entities找到了解决方案。
为了扩展AuditLog类,必须使用继承。因此,一个新类,假设ExtendedAuditInfo需要从AuditLog.
public class ExtendedAuditLog : AuditLog
{
public ExtendedAuditLog()
{
}
public ExtendedAuditLog(AuditInfo auditInfo)
{
this.BrowserInfo = auditInfo.BrowserInfo;
this.ClientIpAddress = auditInfo.ClientIpAddress;
this.ClientName = auditInfo.ClientName;
this.CustomData = auditInfo.CustomData;
this.Exception = auditInfo.Exception?.Message.ToString() + "";
this.ExecutionDuration = auditInfo.ExecutionDuration;
this.ExecutionTime = auditInfo.ExecutionTime;
this.ImpersonatorTenantId = auditInfo.ImpersonatorTenantId;
this.ImpersonatorUserId = auditInfo.ImpersonatorUserId;
this.MethodName = auditInfo.MethodName;
this.Parameters = auditInfo.Parameters;
this.ReturnValue = auditInfo.ReturnValue;
this.ServiceName = auditInfo.ServiceName;
this.TenantId = auditInfo.TenantId;
this.UserId = auditInfo.UserId;
}
//new properties
}
必须将此类添加到上下文中,显然,需要运行新的迁移才能添加新属性。
public class ProjectDbContext : AbpZeroDbContext<Tenant, Role, User, ProjectDbContext >
{
/* Define a DbSet for each entity of the application */
public SerafinaDbContext(DbContextOptions<SerafinaDbContext> options)
: base(options)
{
}
public virtual DbSet<County> Counties { get; set; }
public virtual DbSet<Country> Countries { get; set; }
public virtual DbSet<Currency> Currencies { get; set; }
public virtual DbSet<OrganisationType> OrganisationTypes { get; set; }
public virtual DbSet<ExtendedAuditLog> ExtendedAuditLogs { get; set; }
}
最后,在ExtendedAuditStore类中,IRepository<ExtendedAuditLog, long> _extendedAuditLogRepository必须作为构造函数的第二个参数注入,并且可以用于插入扩展实体。
public class ExtendedAuditStore : AuditingStore
{
IRepository<ExtendedAuditLog, long> _extendedAuditLogRepository;
public ExtendedAuditStore(
IRepository<AuditLog, long> auditLogRepository,
IRepository<ExtendedAuditLog, long> extendedAuditLogRepository
)
: base(auditLogRepository)
{
_extendedAuditLogRepository = extendedAuditLogRepository;
}
public override async Task SaveAsync(AuditInfo auditInfo)
{
if (auditInfo.Exception != null)
await base.SaveAsync(auditInfo);
var auditLog = new ExtendedAuditLog(auditInfo);
//new properties can be set here
await _extendedAuditLogRepository.InsertAsync(auditLog);
}
}
此外,可以创建 IAuditingStore 的新实现并将其注入到应用程序服务中,而不是从 AuditingStore 继承。
更新:
最后,所有你需要的是替换默认AuditingStore的StartUp类:
public IServiceProvider ConfigureServices(IServiceCollection services)
{
services.AddTransient<IAuditingStore, ExtendedAuditStore>();
}
