请尝试下面的架构。您的架构有一些语法错误，有一些不需要的冒号（只有struct type中的字段名才需要冒号）和缺少的数组类型。

myjsondataDDL = """
    address_id INT,
    birth_country String,
    birthdate date,
    customer_id INT,
    demographics STRUCT<buy_potential: string, credit_rating: string, education_status: string, income_range: array<int>, purchase_estimate:INT, vehicle_count: INT>,
    email_address string,
    firstname string,
    gender string,
    is_preffered_customer string,
    lastname string,
    salutation string

myjsondata = spark.read.schema(myjsondataDDL).json('absolute path of file')
