[GitHub] [dubbo-go] yukinomiu opened a new issue, #2410: Dubbo-go作为Provider时, RPC返回的结构体中如果包含指针字段, Java端无法正确解析
yukinomiu opened a new issue, #2410:
URL: https://github.com/apache/dubbo-go/issues/2410
### Environment
- Server: Dubbo-go, v3.10
- Client: dubbo-spring-boot-starter, v3.2.5
- Protocol: dubbo
- Registry: Nacos, v2.2.2
### Issue description
Dubbo-go作为Provider, RPC接口返回结构体指针. 这个结构体内包含一个指针类型的字段.
Java Dubbo作为Consumer, 调用接口, 无法解析结果.
Provider端代码:
```
type TestService interface {
Test(ctx context.Context, req *Req) (*Resp, error)
}
type Resp struct {
Total *int64
}
```
Consumer端代码:
```
public interface TestService {
Resp test(Req request);
}
public class Resp implements Serializable {
private Long total;
public Long getTotal() {
return total;
}
public void setTotal(Long total) {
this.total = total;
}
}
```

另外, 如果请求结构体中有指针类型 `*int64`, 那么Java侧可以正确使用 `java.lang.Long` 进行映射.

I tested this issue against the current dubbo-go main branch with dubbo-go-hessian2 v1.13.2.
I verified the full Dubbo RPC path from a Dubbo-Go provider to a Java Dubbo consumer.
Both cases work correctly:
- non-nil *int64 is deserialized as Java Long with the expected value
- nil *int64 is deserialized as Java Long null
I could no longer reproduce the original issue. It appears this has already been fixed in the newer Hessian2 implementation.

Hi, I'd like to work on this issue as my first contribution to Dubbo-Go.
I'll first try to reproduce the pointer-field interoperability problem against the current main branch and verify whether it still exists with the latest dubbo-go/hessian2 implementation.
If the issue is still valid, I'd like to investigate the serialization path and add a regression test before making the fix. Could you please let me know if this issue is still available to work on?
