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", 1); ProductName = ConfigUtils.GetSetting("Product.Name", "Game"); ProductServerId = ConfigUtils.GetSetting("Product.ServerId", 1); UserLoginDecodeKey = ConfigUtils.GetSetting("Product.ClientDesDeKey", ""); ClientVersion = new Version(1, 0, 0); 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", 500); 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="0"/>
</appServerConfigger>
这样在 GetSection 时，执行 add 操作时就会抛出异常了。
