问题描述

使用dubbo3.2.11，序列化方式为fastjson2。当服务端模型新增字段并升级了jar包，而客户端未升级到最新jar包版本时，偶发历史字段的丢失

环境信息

  • OS信息： Amazon Linux 2023.6.20241111
  • JDK信息： openjdk 17.0.11
  • 版本信息：Fastjson 2.0.51

重现步骤

服务间通过dubbo3.2.11进行rpc调用，序列化方式默认为fastjson2。服务端接口返回模型新增字段并升级jar包版本，客户端仍使用原jar包版本。例如，在订单的菜品模型中新增以下模型：

@Data
public class FulfillmentItemDTO implements Serializable {
    private Long fulfillmentItemId;
    private Integer status;
    private Long operateTime;
}

对比服务端、客户端的日志信息：
Image
菜品的status字段非高版本jar包新增，但客户端反序列化时该字段丢失了。（且在上面的例子中，除了菜品模型外，订单所有模型中的status字段在反序列化时全部丢失了，即使那些模型没有任何变更）

期待的正确结果

低版本客户端反序列化的结果中，高版本jar包新增的字段为null，但历史已有的字段不丢失（也就是最基础的向前兼容）。

相关日志输出

客户端反序列化过程中静默丢失字段，无任何报错。使用丢失的历史字段时可能产生npe

附加信息
