fastjson2什么版本？

[Skqing]

改了DTO里的值，需要在类里面加上 private static final long serialVersionUID = -7403699734166902222L;

[bert82503]

温少，我们升级到dubbo-3.2.10、fastjson2-2.0.43，还有遇到这个问题。
麻烦帮忙再看下，感谢 @wenshao

我们排查到的一些信息与线索，消费者和提供者使用的响应结构有一些差异，JSONB协议通过字段类型和顺序进行了数据空间压缩，丢失字段名称，会带来对象字段签名问题(与方法参数列表签名类似)，不能随意在中间任意位置增加新的字段。新的字段，需要添加在对象末尾。
不知道我这样理解，对不对？

@bert82503 不影响的，你遇到的问题是忽略不存在的字段有BUG，我这两天发布一个版本修复掉就好了。

[bert82503]

👍 好的，感谢解惑 @wenshao

[bert82503]

温少，我的理解，skip not support type INT32 69 与68是类似的问题。
需要提供CommonResponse结构定义么？ @wenshao

@bert82503 不需要，问题已经修复，等发版本

[wenshao]

https://github.com/alibaba/fastjson2/releases/tag/2.0.46
问题已修复，请用新版本

看了JSONReaderJSONB.skipValue()的default:这块实现逻辑，BC_INT32_*_MIN比BC_INT64_*_MIN少BC_INT32_SHORT_MIN

• BC_INT64_NUM_MIN、BC_INT64_NUM_MAX，BC_INT64_BYTE_MIN、BC_INT64_BYTE_MAX，BC_INT64_SHORT_MIN、BC_INT64_SHORT_MAX
• BC_INT32_NUM_MIN、BC_INT32_NUM_MAX，BC_INT32_BYTE_MIN、BC_INT32_BYTE_MAX
