最近在Web环境下使用mybatis,在Winform和服务模式下运行(多线程访问数据库)没有问题。但是在IIS的环境中出现了一个WebSessionStore: Could not obtain reference to HttpContext 异常。
之前有听说过mybatis在多线程模式下会有异常,不过一直没有遇到过.以为是老版本的问题,也没在意。直到今天遇到这个问题才想起这么个事，首先问度娘，找到了这篇文章。感谢二位。

不过我在配置中没有找到配置的方法，在源码中倒是有这么一段：
[Test] public void Can_plug_HybridWebThreadSessionStore() { string uri = "assembly://Apache.Ibatis.DataMapper.SqlClient.Test/bin.Debug/SqlMap_Test_Configure.config"; IResource resource = ResourceLoaderRegistry.GetResource(uri); //主要是这个(楼主注) ConfigurationSetting setting = new ConfigurationSetting(); setting.SessionStore = new HybridWebThreadSessionStore("test"); setting.ValidateMapperConfigFile = true; IConfigurationEngine engine = new DefaultConfigurationEngine(setting); engine.RegisterInterpreter(new XmlConfigurationInterpreter(resource)); IMapperFactory mapperFactory = engine.BuildMapperFactory(); IDataMapper dataMapper = ((IDataMapperAccessor)mapperFactory).DataMapper; Account account = dataMapper.QueryForObject<Account>("GetAccountViaResultClass", 1); Assert.AreEqual(1, account.Id, "account.Id"); Assert.AreEqual("Joe", account.FirstName, "account.FirstName"); Assert.AreEqual("Dalton", account.LastName, "account.LastName"); Assert.AreEqual("Joe.Dalton@somewhere.com", account.EmailAddress, "account.EmailAddress"); }
于是按照这个在代码中进行了一下修改,问题果然解决了。回头在翻翻相关文档，补充一下如果在配置文件中进行配置,有知道的也欢迎指出。
这篇文章也有详细的说明:
