当使用一个复杂的 final class 来作为 final static string 常量的保存地。性能是否有影响

主要问题是，需要保存非常大量的字符串常量。

我希望可以把这些常量管理起来。所以现在是使用大量的内部类管理。

不仅包含大量的内部类。内部类中还包含内部类。不知道这样会不会影响性能问题。

示例：
```

public final class WmsUrlConstants {

public static final String URL_WMS_DEFAULT_INDEX = "/wms/default/index";

public static final class Transfer {

    public static final String search = "/wms/transfer/list/search";

    public static final String delete = "/wms/transfer/list/delete";

    public static final String get = "/wms/transfer/edit/getTransfer";

    public static final String submit = "/wms/transfer/edit/submitTransfer";

    public static final String save = "/wms/transfer/edit/saveTransfer";

    public static final String create = "/wms/transfer/edit/create";

    public static final class Package {

        public static final String save = "/wms/transfer/edit/savePackage";

        public static final String delete = "/wms/transfer/edit/deletePackage";

        public static final class Item {

            public static final String select = "/wms/transfer/edit/getPackageItems";
        }
    }

    public static final class Product {

        public static final class Sku {

            public static final String get = "/wms/transfer/edit/getSkuByCode";
        }
    }

    public static final class Store {

        public static final String all = "/wms/transfer/edit/getAllWarehouses";
    }
}

}
