ClickHouseArray序列化異常

1.異常

Caused by: com.fasterxml.jackson.databind.JsonMappingException: (was java.sql.SQLFeatureNotSupportedException) (through reference chain: com.****.HttpResult["content"]->java.util.ArrayList[0]->java.util.LinkedHashMap["column_14"]->ru.yandex.clickhouse.ClickHouseArray["resultSet"])

使用jdbc操作clickhouse執行sql的返回結果時報錯

2、項目中其他語句都沒有報錯，只有在返回 ClickHouseArray 這個類的時候序列化異常。沒有看到其他解法，就自己實現序列化和反序列的代碼。
