我使用以下内容:
public interface IRepository<T>
{
void Add(T entity);
}
public class Repository<T>
{
private readonly ISession session;
public Repository(ISession session)
{
this.session = session;
}
public void Add(T entity)
{
session.Save(entity);
}
}
public class SomeHandler : IHandleMessages<SomeMessage>
{
private readonly IRepository<EntityA> aRepository;
private readonly IRepository<EntityB> bRepository;
public SomeHandler(IRepository<EntityA> aRepository, IRepository<EntityB> bRepository)
{
this.aRepository = aRepository;
this.bRepository = bRepository;
}
public void Handle(SomeMessage message)
{
aRepository.Add(new A(message.Property);
bRepository.Add(new B(message.Property);
}
}
public class MessageEndPoint : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization
{
public void Init()
{
ObjectFactory.Configure(config =>
{
config.For<ISession>()
.CacheBy(InstanceScope.ThreadLocal)
.TheDefault.Is.ConstructedBy(ctx => ctx.GetInstance<ISessionFactory>().OpenSession());
config.ForRequestedType(typeof(IRepository<>))
.TheDefaultIsConcreteType(typeof(Repository<>));
}
}
我对线程本地存储的问题是,在整个应用程序线程中使用相同的会话。当我看到一级缓存未被清除时,我发现了这一点。我想要的是在每次调用 IHandleMessages<>.Handle 之前使用一个新的会话实例。我怎样才能用结构图做到这一点?我必须创建一个消息模块吗?
