How to use product-no as URL slug

Just change the routeFieldName: product_no into the desired field. It's important that the routeValuePrefix: '' is set to an empty string, otherwise the PersistedAliasMapper has a / prefixed and won't field your product in database.

  ShopProductsPlugin:
    type: Extbase
    limitToPages:

    extension: Shop
    plugin: Products
    routes:

        routePath: '/{product_slug}'
        _controller: 'Product::show'
        _arguments:
          product_slug: product
    defaultController: 'Product::list'
    aspects:
      product_slug:
        type: PersistedAliasMapper
        tableName: tx_shop_domain_model_product
        routeFieldName: product_no
        routeValuePrefix: ''
