[zhushengjun-it]

What happened:
go-mod:
go 1.15

  require (
    dubbo.apache.org/dubbo-go/v3 v3.0.0-rc4-1.0.20211116041552-b90089d8b8a3
    github.com/apache/dubbo-go-hessian2 v1.9.3
 )

What you expected to happen:
go client调用javaserver时，javaserver获取到的接口的入参为空的情况。
How to reproduce it (as minimally and precisely as possible):
server:

     public class BaseTestRpcBO implements Serializable {

             private LigoLastMsgInfo ligoLastMsgInfo;

             private long testId;

             private String testContent;

             private Map<String, String> testMap;

             protected Set<String> testSet = new LinkedHashSet<>();

             private Date testDateTime;

             }

             public class LigoLastMsgInfo implements Serializable {

                 private static final long serialVersionUID = -1295732691903413324L;

                 private long messageId;

                 private String text;

                 private Date messageTime;
             }

go client:

func main() {
err := config.Load()
if err != nil {
	fmt.Println(fmt.Sprintf("err:%v", err))
	logger.Errorf("init load config error:%v", err)
	os.Exit(-1)
}
time.Sleep(3e9)
textMessage := text.BaseTestRpcBO{}
textMessage.LigoLastMsg = new(text.LigoLastMsgInfo)
textMessage.LigoLastMsg.Text = "123123123"
textMessage.LigoLastMsg.MessageId = 23213
t := time.Now()
textMessage.ExtendContent = "123321"
textMessage.TestDateTime = &t
resp, errGet := model.TxtProvider.TestRpcApiV2(context.Background(), "vgroup test content", 11223344, textMessage)
if errGet != nil {
	logger.Errorf("response error:%v", errGet)
}
logger.Infof("resp:%v", resp)

}
go model:

func InitTestRpcBo() {
  // ------for hessian2------
  hessian.RegisterPOJO(&BaseTestRpcBO{})
  hessian.RegisterPOJO(&TestRpcBO{})
  hessian.RegisterPOJO(&SecondTestRpcBO{})
  hessian.RegisterPOJO(&LigoLastMsgInfo{})
}


type BaseTestRpcBO struct {
  LigoLastMsg   *LigoLastMsgInfo
  TextMap       map[string]string
  TextSet       []string
  ExtendId      int64
  ExtendContent string
  TestDateTime  *time.Time
}




 func (baseTestRpcbo BaseTestRpcBO) JavaClassName() string {
      return "xx.xx.xx.BaseTestRpcBO"
 }



type TestRpcBO struct {
  BaseTestRpcBO
  ExtendId      int64

func (testRpcBo TestRpcBO) JavaClassName() string {
  return "xx.xx.xx.TestRpcBO"
}




 type SecondTestRpcBO struct {
  BaseTestRpcBO
  SecondId      int32
  SecondContent string
 }



func (secondTestRpcBo SecondTestRpcBO) JavaClassName() string {
return "xx.xx.xx.secondTestRpcBO"
}


type LigoLastMsgInfo struct {
  MessageId   int32
  Text        string
  MessageTime time.Time
}



 func (ligoLastMsgInfo LigoLastMsgInfo) JavaClassName() string {
    return "xx.xx.xx.LigoLastMsgInfo"
 }

provider:

      type ChatSystemApi struct {
  // dubbo标签，用于适配go侧客户端大写方法名 -> java侧小写方法名，只有 dubbo 协议客户端才需要使用
            SendMessage  func(ctx context.Context, from int64, message message.Message) (*CommResp, error)                                `dubbo:"sendMessage"`
            TestRpcApi   func(ctx context.Context, testContent string, testId int64, message message.Message) (*CommResp, error)          `dubbo:"testRpcApi"`
            TestRpcApiV2 func(ctx context.Context, testContent string, testId int64, baseTestRpcBO text.BaseTestRpcBO) (*CommResp, error) `dubbo:"testRpcApiV2"`

}

      var (
          TxtProvider *ChatSystemApi
      )

      func ProviderInit() {
          TxtProvider = &ChatSystemApi{}
          //	注册客户端存根类到框架，实例化客户端接口指针
          config.SetConsumerService(TxtProvider)
      }

      func (msg ChatSystemApi) JavaClassName() string {
          return "xx.xx.xx.ChatSystemApi"
      }
