JsonMappingException：当前令牌不是START_OBJECT（需要解包根名'Transaction []'），而是START_ARRAY

您只需要在Transaction顶部添加其他包装类型，也请删除UNWRAP_ROOT_VALUE选项。

这些类将遵循以下原则：

public class TransactionHolder {    private Transaction transaction;... }public class Transaction {    private String amount_in_cents;    private String created_at;    private int ending_balance_in_cents;    private int id;    private String kind;    private String memo;    private int payment_id;    private int product_id;    private int subscription_id;    private boolean success;    private String transaction_type;    private String type;...}

使用您的示例json，以下内容对我来说很干净：

ObjectMapper mapper = new ObjectMapper();InputStream is = this.getClass().getResourceAsStream("sample.json");TransactionHolder[] holders = mapper.readValue(is,TransactionHolder[].class);
