由于我对 PostSharp（最新版本）知之甚少，我有 2 个错误。我的项目的三个方面类，但我只得到 2 个错误。当 getall 方法在我的 mvc 项目中运行时，我希望在我的数据库和 C:/Log/Log.txt 中生成日志信息。但是没有创建日志。这是我想从你这里得到的。无论我如何编写代码块，我的问题都解决了吗？我有一些验证和交易流程，但我认为这与我遇到的错误没有任何关系，因此无需详细说明。首先，我收到以下警告。
为了解决这个问题，我按照以下步骤操作。LogAspect 和 FluentValidationAspect 类一直出错。
[LogAspect(AspectPriority = 1), FluentValidationAspect(AspectPriority = 2), TransactionScopeAspect(AspectPriority = 3)]
再一次，我得到了以下错误。(CS 7036)
我想在我的 BookManager 类中做一些操作。（日志、验证、交易）。这是代码；
[LogAspect(AspectPriority = 1), FluentValidationAspect(AspectPriority = 2), TransactionScopeAspect(AspectPriority = 3)]
public class BookManager : IBookService
{
private IBookDal _bookDal;
private IPersonDal _personDal;
/* private readonly IQueryableRepository<Book> _queryable; */
public BookManager(IBookDal bookDal, IPersonDal personDal/*IQueryableRepository<Book> queryable */)
{
_personDal = personDal;
/*_queryable = queryable; */
_bookDal = bookDal;
}
[FluentValidationAspect(typeof(BookValidator))]
public Book Add(Book book)
{
return _bookDal.Add(book);
}
public void Delete(Book book)
{
_bookDal.Delete(book);
}
[LogAspect(typeof(DatabaseLogger))]
public List<Book> GetAll()
{
return _bookDal.GetList();
}
[TransactionScopeAspect]
public void TransactionalOperation(Person person, Book book)
{
_personDal.Delete(person);
// Business Codes
_bookDal.Add(book);
}
public Book GetById(int bookId)
{
return _bookDal.Get(p=>p.BookId==bookId);
}
[FluentValidationAspect(typeof(BookValidator))]
public Book Update(Book book)
{
return _bookDal.Update(book);
}
}
[Serializable]
[MulticastAttributeUsage(MulticastTargets.Method, TargetMemberAttributes = MulticastAttributes.Instance)]
public class LogAspect : OnMethodBoundaryAspect
{
private Type _loggerType;
[NonSerialized]
private LoggerService _loggerService;
public LogAspect(Type loggerType)
{
_loggerType = loggerType;
}
public override void RuntimeInitialize(MethodBase method)
{
if (_loggerType.BaseType != typeof(LoggerService))
{
throw new Exception("Wrong logger type.");
}
_loggerService = (LoggerService)Activator.CreateInstance(_loggerType);
base.RuntimeInitialize(method);
}
public override void OnEntry(MethodExecutionArgs args)
{
if (!_loggerService.IsInfoEnabled)
{
return;
}
try
{
var logParameters = args.Method.GetParameters().Select((t, i) => new LogParameter
{
Name = t.Name,
Type = t.ParameterType.Name,
Value = args.Arguments.GetArgument(i)
}).ToList();
var logDetail = new LogDetail
{
FullName = args.Method.DeclaringType == null ? null : args.Method.DeclaringType.Name,
MethodName = args.Method.Name,
Parameters = logParameters
};
_loggerService.Info(logDetail);
}
catch (Exception)
{
}
}
}
[Serializable]
public class FluentValidationAspect : OnMethodBoundaryAspect
{
Type _validatorType;
public FluentValidationAspect(Type validatorType)
{
_validatorType = validatorType;
}
public override void OnEntry(MethodExecutionArgs args)
{
var validator = (IValidator)Activator.CreateInstance(_validatorType);
var entityType = _validatorType.BaseType.GetGenericArguments()[0];
var entities = args.Arguments.Where(t => t.GetType() == entityType);
foreach (var entity in entities)
{
ValidatorTool.FluentValidate(validator, entity);
}
}
}
我想告诉你一些你必须考虑的事情。另外，我做了汇编级别的日志记录。这是代码。
[assembly: LogAspect(typeof(JsonFileLogger), AttributeTargetTypes = "ELibrary.Library.Business.Managers.BookManager*")]
最后我想补充一下，能否通过重写错误的块来解释这个错误的解决方案？
