我使用Rob的mvc startesite http://mvcstarter.codeplex.com/與ASP.Net MVC 2,Ninject2,NoRM(http://github.com/atheken/NoRM)和MongoDB。它的工作速度非常快,開發速度更快,但我面臨一個大問題,我在某些時候會遇到連接超時。我無法弄清楚我做錯了什麼。Norm.MongoException:連接超時嘗試從連接池中獲取連接
我已經在這裏問過一個問題:I get this error that I don't understand why, using NoRM and Mongo in my MVC project和這裏http://groups.google.com/group/norm-mongodb/browse_thread/thread/7882be16f030eb29但我仍然在黑暗中。
非常感謝您的幫助!
EDITED * 這裏是我的MongoSession對象: 公共類MongoSession:ISession的{
private readonly Mongo _server;
public MongoSession()
{
//this looks for a connection string in your Web.config - you can override this if you want
_server = Mongo.Create("MongoDB");
}
public T Single<T>(System.Linq.Expressions.Expression<Func<T, bool>> expression) where T : class {
return _server.GetCollection<T>().AsQueryable().Where(expression).SingleOrDefault();
}
public IQueryable<T> All<T>() where T : class {
return _server.GetCollection<T>().AsQueryable();
}
public void Save<T>(IEnumerable<T> items) where T : class {
foreach (T item in items) {
Save(item);
}
}
public void Save<T>(T item) where T : class {
var errors = DataAnnotationsValidationRunner.GetErrors(item);
if (errors.Count() > 0)
{
throw new RulesException(errors);
}
_server.Database.GetCollection<T>().Save(item);
}
public void Delete<T>(System.Linq.Expressions.Expression<Func<T, bool>> expression) where T : class
{
var items = All<T>().Where(expression);
foreach (T item in items)
{
Delete(item);
}
}
public void Delete<T>(T item) where T : class
{
_server.GetCollection<T>().Delete(item);
}
public void Drop<T>() where T : class
{
_server.Database.DropCollection(typeof(T).Name);
}
public void Dispose() {
_server.Dispose();
}
}
現在我MongoRepositoryBase
public abstract class MongoRepositoryBase<T> : ISession<T> where T : MongoObject
{
protected ISession _session;
protected MongoRepositoryBase(ISession session)
{
_session = session;
}
public T Single(ObjectId id)
{
return _session.All<T>().Where(x => x.Id == id).FirstOrDefault();
}
public T Single(Expression<Func<T, bool>> expression)
{
return _session.Single(expression);
}
public IQueryable<T> All()
{
return _session.All<T>();
}
public void Save(IEnumerable<T> items)
{
foreach (T item in items)
{
Save(item);
}
}
public void Save(T item)
{
_session.Save(item);
}
public void Delete(System.Linq.Expressions.Expression<Func<T, bool>> expression)
{
var items = _session.All<T>().Where(expression);
foreach (T item in items)
{
Delete(item);
}
}
public void DeleteAll()
{
var items = _session.All<T>();
foreach (T item in items)
{
Delete(item);
}
}
public void Delete(T item)
{
_session.Delete(item);
}
public void Drop()
{
_session.Drop<T>();
}
public void Dispose()
{
_session.Dispose();
}
}
和另一庫implemantation的爲例:
public class PlaceRepository : MongoRepositoryBase<Place>, IPlaceRepository
{
public PlaceRepository(ISession session) : base(session)
{
}
public List<Place> GetByCategory(PlaceCategory category, bool publishedOnly)
{
var query = _session.All<Place>()
.OrderBy(x => x.Name)
.Where(x => x.Category == category);
if (publishedOnly) query = query.Where(x => x.Published);
if (publishedOnly) query = query.Where(x => x.ShowOnMap);
return query.ToList();
}
public Place FindByName(string name)
{
var query = _session.All<Place>()
.Where(x => x.Name.ToLower().Contains(name.ToLower()))
.Where(x => x.Published);
return query.FirstOrDefault();
}
public string[] FindSuggestionsByName(string name)
{
var query = _session.All<Place>()
.OrderBy(x => x.Name)
.Where(x => x.Name.ToLower().StartsWith(name.ToLower()))
.Where(x => x.Published);
var places = query.ToList();
var names = new string[places.Count];
var i = 0;
foreach (var place in places)
{
names[i++] = place.Name;
}
return names;
}
}
那麼容易 - 可能重複的[我得到這個錯誤,我不明白爲什麼,在我的MVC項目中使用NoRM和Mongo](http://stackoverflow.com/questions/3159811/i-get-這錯誤,我不知道爲什麼使用規範和mongo在我的mvc項目) – jfar 2010-08-10 17:13:54
我知道,這是讓我瘋了!我用另一個標題和不同的解釋和關鍵字,也許我可以找到人來幫助我......我添加了更多的代碼。 – VinnyG 2010-08-10 23:03:11
