+指定保存到的配置文件层级是项目用户设置 Project/Config/UserXXX.ini。

+## 示例代码：
+
+保存的目录是\Hello\Config\UserMyGame.ini
+
+```cpp
+UCLASS(Config = MyGame, ProjectUserConfig)
+class INSIDER_API UMyClass_ProjectUserConfig :public UDeveloperSettings
+{
+	GENERATED_BODY()
+public:
+	/** Gets the settings container name for the settings, either Project or Editor */
+	virtual FName GetContainerName() const override { return TEXT("Project"); }
+	/** Gets the category for the settings, some high level grouping like, Editor, Engine, Game...etc. */
+	virtual FName GetCategoryName() const override { return TEXT("MyGame"); }
+	/** The unique name for your section of settings, uses the class's FName. */
+	virtual FName GetSectionName() const override { return TEXT("MyProjectGame"); }
+public:
+	UPROPERTY(EditAnywhere, BlueprintReadWrite, Config)
+		int32 MyPropertyWithConfig = 123;
+
+	UPROPERTY(EditAnywhere, BlueprintReadWrite, GlobalConfig)
+		int32 MyPropertyWithGlobalConfig = 456;
+};
+
+//结果：\Hello\Config\UserMyGame.ini
+[/Script/Insider.MyClass_ProjectUserConfig]
+MyPropertyWithConfig=777
