アプリケーションがデータベースソースから構成を読み取る必要がありますが、構成とパフォーマンスを更新する柔軟性を満たすために、独自のキャッシュメカニズムを適用する必要があります（値が必要なときにデータベースにアクセスしない）
キャッシュメカニズムを実行するサービスはSymbolSourceImplです。JVMオプションなどのキャッシュ可能な値をキャッシュするためにタペストリーが必要なので。別のシンボルソースを提供する必要があります。しかし、SymbolObjectProvider（Contributed to MasterObjectProvider）はのインスタンスを1つしか保持せず、デフォルトのバインディングSymbolSourceをオーバーライドできないため、タペストリーがdefaultで行ったようSymbolSourceに、まったく別のシンボルオブジェクトプロバイダーを提供することを考えました。MasterObjectProviderSymbolObjectProvider
しかし、私が自分のシンボルオブジェクトプロバイダーに貢献しようとしたときに問題が発生します。
@Contribute(MasterObjectProvider.class)
public static void setupDBSYmbolObjectProviders(OrderedConfiguration<ObjectProvider> configuration) {
configuration.addInstance("DBSymbol", **DBSymbolObjectProvider**.class, OrderConstraintBuilder.before("Symbol").build());
}
私のDBSymbolObjectProviderコンストラクターは次のようになります。
public DBSymbolObjectProvider(IDBSymbolSource symbolSource, @Builtin TypeCoercer typeCoercer) {
this.symbolSource = symbolSource;
this.typeCoercer = typeCoercer;
}
タペストリーは解決されTypeCoercerましたが、解決できずIDBSymbolSource、次の例外がスローされました。これは、MasterObjectProviderがまだ解決するように構築されていないため、論理的IDBSymbolSourceです。
