谢谢各位，我已经找到原因，由于类的泛型层级过深，在方法的返回类型上没有给出完整的泛型类型，类似这样：A<B<C>>，我是这样的A<>，在传递过程中C这一层变成了HashMap格式，也就丢失了@JsonFormat注解。在dubbo 3.2.0和之前的版本是没有这个问题的，可能是因为使用的是hessian2，而fastjson2并没有处理那么深的层级。

dubbo在3.2.x后将默认序列化由hessian2替换为了Fastjson2
你可以引入依赖，在dubbo配置文件中进行修改即可

`@JsonFormat` 是加在 Spring Controller 的参数里面还是 Dubbo 请求的参数里面
