因为一些配置属性比较多，存在多组属性，因此结合xml解析、缓存技术，实现配置文化的自动解析、存入缓存、缓存依赖实时更新配置内容。
配置文件反序列化存入缓存的核心方法：
public Class.Settings GetSettings()
{
if (HttpRuntime.Cache["settings"] != null)
return (Class.Settings)HttpRuntime.Cache["settings"];
string rootPath = GetPath();
#region rootPath
if (rootPath == "")
{
log.Write(MsgType.Fatal, "配置文件根目录rootPath为空");
return null;
}
else
{
if (!rootPath.EndsWith("\\"))
rootPath += "\\";
rootPath = rootPath + "settings\\settings.config";
}
#endregion
if (!File.Exists(rootPath))
{
log.Write(MsgType.Fatal, "配置文件根目录rootPath为空");
return null;
}
string content = File.ReadAllText(rootPath, Encoding.Default);
Class.Settings model = PublicMethod.XmlSerialize.DeserializeXML<Class.Settings>(content);
log.Write(MsgType.Information, "读取配置文件");
CacheDependency cd = new CacheDependency(rootPath);
HttpRuntime.Cache.Add("settings", model, cd, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.High, null);
return model;
}
上面自动获取rootPath的方法：
/// <summary>
/// 取当前根目录的方法
/// </summary>
private static string GetPath()
{
string rootPath = "";
System.Diagnostics.Process p = System.Diagnostics.Process.GetCurrentProcess();
//WebDev.WebServer visual studio web server
//xxx.vhost Winform
//w3wp IIS7
//aspnet_wp IIS6
//iisexpress vs2013
string processName = p.ProcessName.ToLower();
if (processName == "aspnet_wp" || processName == "w3wp" || processName == "webdev.webserver" || processName == "iisexpress")
{
if (System.Web.HttpContext.Current != null)
rootPath = System.Web.HttpContext.Current.Server.MapPath("~/");
else //当控件在定时器的触发程序中使用时就为空
{
rootPath = System.AppDomain.CurrentDomain.BaseDirectory;
}
}
return rootPath;
}
Settings实体类的定义，要注意，这里的实体类要和settings配置文件对应，否则反序列化会出错：
[XmlRoot(Namespace = "", IsNullable = false, ElementName = "settings")]
public class Settings
{
#region 属性
[XmlElement("logger")]
public LoggerConfig logger { get; set; }
#endregion
#region 子类
[XmlType(TypeName = "logger")]
public class LoggerConfig
{
public string loglevel { get; set; }
public string savepath { get; set; }
}
#endregion
}
settings.config的内容实例
<?xml version='1.0' encoding='utf-8'?> <settings> <logger> <loglevel>0</loglevel> <savepath>d:\log</savepath> </logger> <queryurl>http://11.56.254.234:88/shashachaxunserver/shashachaxun</queryurl> <receiveurl>http://172.16.1.131:88/ThirdPay/ChinaUMS/xml.aspx</receiveurl> <turnurl>http://172.16.1.131:88/ThirdPay/ChinaUMS/query.aspx</turnurl> </chinaums> </settings>
