Environment

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;
    }
}

根据 dubbo-go-hessian2 文档, Golang使用 *int64 , Java使用 java.lang.Long , 预期Java可以正确解析, 实测反序列化失败.

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.

chickenlj commented 1 year ago

@yukinomiu 有具体的报错信息吗。我怀疑是hessian-go序列化相关的兼容性问题。

DMwangnima commented 1 year ago

@yukinomiu Try to use long instead of Long.

yukinomiu commented 11 months ago

@DMwangnima DM long is ok, but I need Long for null value.

Consumer:

public class TestLongReq implements Serializable {
    private Long total;

    public Long getTotal() {
        return total;
    }

    public void setTotal(Long total) {
        this.total = total;
    }
}

public class TestLongResp implements Serializable {
    private Long total;

    public Long getTotal() {
        return total;
    }

    public void setTotal(Long total) {
        this.total = total;
    }
}

TestLongResp TestLong(TestLongReq req) throws Exception;

Provider:

type TestLongReq struct {
    Total *int64
}

func (req *TestLongReq) JavaClassName() string {
    return "org.apache.dubbo.samples.api.TestLongReq"
}

type TestLongResp struct {
    Total *int64
}

func (req *TestLongResp) JavaClassName() string {
    return "org.apache.dubbo.samples.api.TestLongResp"
}

func (u *UserProviderImpl) TestLong(ctx context.Context, req *TestLongReq) (*TestLongResp, error) {
    return &TestLongResp{Total: req.Total}, nil
}

dubbo:
  protocols:
    dubbo:
      name: dubbo
      port: 20001
  provider:
    services:
      UserProviderImpl:
        interface: org.apache.dubbo.samples.api.UserProvider

@yukinomiu This works fine.
