先上一段代码：
public EnvironmentSetting()
{
var appServer = GetServerSection();
var protocol = GetProtocolSection();
var cacheSection = GetCacheSection();
var scriptSection = GetScriptSection(); CacheGlobalPeriod = cacheSection.ShareExpirePeriod;
CacheUserPeriod = cacheSection.PersonalExpirePeriod; ScriptSysAsmReferences = scriptSection.SysAssemblyReferences;
ScriptAsmReferences = scriptSection.AssemblyReferences;
GamePort = protocol.GamePort;
GameIpAddress = string.IsNullOrEmpty(protocol.GameIpAddress) ? GetLocalIp() : protocol.GameIpAddress; try
{
if (!string.IsNullOrEmpty(appServer.EntityAssemblyName))
{
EntityAssembly = Assembly.LoadFrom(appServer.EntityAssemblyName);
}
}
catch (Exception ex)
{
TraceLog.WriteError("Load entity assembly error:\"{0}\" {1}", appServer.EntityAssemblyName, ex);
}
ActionDispatcher = new ScutActionDispatcher();
InitSerializer();
Reset();
}
可以看到，配置都是通过 GetServerSection、GetProtocolSection 等API导入的。
再来看一下 GetServerSction 的具体操作：
private static AppServerSection GetServerSection()
{
return ConfigManager.Configger.GetFirstOrAddConfig<AppServerSection>();
}
public AppServerSection()
{
ProductCode = ConfigUtils.GetSetting("Product.Code", );
ProductName = ConfigUtils.GetSetting("Product.Name", "Game");
ProductServerId = ConfigUtils.GetSetting("Product.ServerId", );
UserLoginDecodeKey = ConfigUtils.GetSetting("Product.ClientDesDeKey", "");
ClientVersion = new Version(, , );
Version ver;
if (Version.TryParse(ConfigUtils.GetSetting("Product.ClientVersion", "1.0.0"), out ver))
{
ClientVersion = ver;
} PublishType = ConfigUtils.GetSetting("PublishType", "Release");
ActionTimeOut = ConfigUtils.GetSetting("ActionTimeOut", );
LanguageTypeName = ConfigUtils.GetSetting("Game.Language.TypeName", "Game.src.Locale.DefaultLanguage"); ActionTypeName = ConfigUtils.GetSetting("Game.Action.TypeName");
if (string.IsNullOrEmpty(ActionTypeName))
{
string assemblyName = ConfigUtils.GetSetting("Game.Action.AssemblyName", "GameServer.CsScript");
if (!string.IsNullOrEmpty(assemblyName))
{
ActionTypeName = assemblyName + ".Action.Action{0}," + assemblyName;
}
}
ScriptTypeName = ConfigUtils.GetSetting("Game.Action.Script.TypeName", "Game.Script.Action{0}");
EntityAssemblyName = ConfigUtils.GetSetting("Game.Entity.AssemblyName");
DecodeFuncTypeName = ConfigUtils.GetSetting("Game.Script.DecodeFunc.TypeName", "");
RemoteTypeName = ConfigUtils.GetSetting("Game.Remote.Script.TypeName", "Game.Script.Remote.{0}");
AccountServerUrl = ConfigUtils.GetSetting("AccountServerUrl", "");
}
ConfigUtils 是控制 app.config 配置的。那么，我们可以很清楚地明白，Scut 的配置，如果在 app.config 中有该字段，则使用配置文件的值，如果没有，则使用程序默认值。
那么，我们是否可以完全由外部配置来启动，并更加清晰地管理外部配置呢？
static EnvironmentSetting()
{
bool result;
try
{
result = ConfigManager.Intialize("appServerConfigger");
}
catch (Exception)
{
result = false;
}
if (!result)
{
try
{
ConfigManager.GetConfigger<DefaultAppConfigger>();
}
catch (Exception ex)
{
TraceLog.WriteError("Configger init error:{0}", ex);
}
}
LoadDecodeFunc();
}
public static bool Intialize(string sectionName)
{
lock (syncRoot)
{
var section = ConfigurationManager.GetSection(sectionName);
if (section is IConfigger)
{
var instance = section as IConfigger;
instance.Install();
_configgerSet.Add(instance);
_configger = instance;
return true;
}
return false;
}
}
我们可以在 static EnvironmentSetting 中，直接从配置文件中读取全部配置：
ConfigManager.Intialize("appServerConfigger");
ConfigManager.Intialize("ProtocolConfigger");
ConfigManager.Intialize("CacheConfigger");
ConfigManager.Intialize("ScriptConfigger");
同时，从 DataDefaultConfigger 派生出 appServerConfigger、ProtocolConfigger、CacheConfigger、ScriptConfigger。
每个 Configger 还应包括相应的配置：AppServerSection、ProtocolSection、CacheSection、ScriptSection。
每个 Configger 还应重写 LoadConfigData 接口，将数据从 .config 中读入 appServerConfigger 的 AppServerSection 中...
最后，还应在 app.config 中添加所有的自定义配置节。
在写 app.config 的过程中出现了问题：
首先测试性地修改 appServerConfigger，添加测试变量：
public class DefaultAppConfigger : DefaultDataConfigger
{
public int ProductCode { get; set; }
...
}
<configSections>
<section name="appServerConfigger" type="ZyGames.Framework.Game.Runtime.DefaultAppConfigger, ZyGames.Framework.Game" requirePermission="false"/>
</configSections> <appServerConfigger>
<add key="ProductCode" value=""/>
</appServerConfigger>
这样在 GetSection 时，执行 add 操作时就会抛出异常了。
