MyBatis.Net使用入门(一)
首先Models层模型如下:
QueryUsageLog.cs，UsageLog.cs和UserInfo.cs
public class QueryUsageLog
{
public string SessionId { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public string MachineName { get; set; }
public string LoginAccount { get; set; }
} public class UsageLog
{
public int Id { get; set; }
public string SessionId { get; set; }
public DateTime TimeStamp { get; set; }
public string LoginAccount { get; set; }
public string MachineName { get; set; }
public string TypeName { get; set; }
public string MethodName { get; set; }
public string Arguments { get; set; }
public string LogMessage { get; set; }
public string ErrorMessage { get; set; }
}public class UserInfo
{
public string UserId { get; set; }
public string ProductId { get; set; }
}文件夹下有5个配置文件，properties.config是连接字符串属性文件：
providers.config是数据库提供程序配置:
sqlFile.xml是数据与实体映射的配置文件:
SELECT Top(1) SessionId
FROM MRUsageLog
WHERE LoginAccount = #value#
select
Id,
SessionId,
TimeStamp,
LoginAccount,
MachineName,
TypeName,
MethodName,
Arguments,
LogMessage,
ErrorMessage
from MRUsageLog
GetUsageLog
Usr_GetUserSettings
SqlMap.config全局配置文件：
public sealed class MyBatisHelper
{
private static volatile ISqlMapper mapper = null;
private static string GetConfigPath()
{
//string baseDir = AppDomain.CurrentDomain.BaseDirectory;
string baseDir = Path.GetFullPath(@"../../"); ;
return baseDir + ConfigurationManager.AppSettings["DBConfig"];
}
public static void Configure(object obj)
{
mapper = (ISqlMapper) obj;
}
public static void InitMapper()
{
string configPath = GetConfigPath();
ConfigureHandler hanlder = new ConfigureHandler(Configure);
DomSqlMapBuilder builder = new DomSqlMapBuilder();
mapper = builder.ConfigureAndWatch(configPath, hanlder);
}
public static ISqlMapper Instance
{
get
{
try
{
if (mapper == null)
{
lock (typeof (SqlMapper))

return mapper;
}
catch (Exception ex)

}
}
}
public static T QueryForObject(string statementName, object parameterObject)
{

return result;
}
catch (Exception ex)
