我的表中的UDT低于
productsinfo FROZEN<productsinfo>
这是productsinfo的UDT模式
"owned_product_details" map<text, FROZEN<list<FROZEN<productdetails>>>>,
"available_product_details" map<text, FROZEN<list<FROZEN<productdetails>>>>
产品详细信息UDT包含一些文本字段
当我尝试使用Java插入值时，它会抛出异常
java.lang.NullPointerException: at index 1

在调试时我发现了这个
suppressedExceptions Collections$UnmodifiableRandomAccessList<E> (id=317)
以下是Java中的实体类
@Column("productsinfo")
@CassandraType(type = DataType.Name.UDT, userTypeName = "productsinfo")
private ProductsInfo productsInfo;
@Column("owned_product_details")
@CassandraType(type = DataType.Name.MAP, typeArguments = { DataType.Name.TEXT, DataType.Name.LIST })
private Map<String, List<ProductDetails>> ownedProductDetails;
@Column("available_product_details")
@CassandraType(type = DataType.Name.MAP, typeArguments = { DataType.Name.TEXT, DataType.Name.LIST })
private Map<String, List<ProductDetails>> availableProductDetails;
