[Bug] configure the serialization mechanism for dubbo-python

Dubbo Version

java 21, dubbo 3.3.4

Steps to reproduce this issue

on the java side:

dubbo:
  application:
    logger: slf4j
    name: chat-service
    qos-enable: false
    check-serializable: true
    auto-trust-serialize-class: true
    trust-serialize-class-level: 3
  registry:
    address: nacos://192.168.124.3:8848?namespace=2b810d86-06c3-4e07-b09f-e85172994090
    register-mode: instance
  protocol:
    name: tri
    port: 20884

@Slf4j
@DubboService(timeout = 10000,protocol = {"tri"})
@Service
public class CalvToolProvider2 implements LLMCalvTool {

    @Override
    public List<Long> demoTest(Long groupID) {
        List<Long> longs = List.of();
        longs.add(1L);
        longs.add(2L);
        longs.add(3L);
        return longs;
    }

    @Override
    public String hello() {
        return "'helooooooo'";
    }

}

the meta data:

dubbo.metadata-service.url-params={"serialization":"hessian2","prefer.serialization":"hessian2","version":"2.0.0","dubbo":"2.0.2","release":"3.3.4","side":"provider","port":"20809","protocol":"tri"}

dubbo.endpoints=[{"port":20884,"protocol":"dubbo"},{"port":20809,"protocol":"tri"}]

dubbo.metadata.revision=33f645ebbe335cc4b8ef0f990d425d2a

dubbo.metadata.storage-type=local

meta-v=2.0.0

timestamp=1744721018804

and on the python side:

import dubbo
from dubbo.configs import ReferenceConfig

class UnaryServiceStub:
    def __init__(self, client: dubbo.Client):
        self.unary_hello = client.unary(method_name="hello")
        self.unary_demoTest = client.unary(method_name="demoTest")

    def get_hello(self):
        return self.unary_hello()

    def get_demoTest(self, groupID):
        return self.unary_demoTest(groupID)

if __name__ == "__main__":
    # 配置参考
    reference_config = ReferenceConfig.from_url(
        "tri://192.168.124.3:20809/com.demo.interfaces.LLMCalvTool?serialization=hessian2",
    )
    # 创建 Dubbo 客户端
    dubbo_client = dubbo.Client(reference_config)
    # 创建服务代理
    unary_service_stub = UnaryServiceStub(dubbo_client)

    # 调用 hello 方法
    result_hello = unary_service_stub.get_hello()
    print(result_hello)

    # 调用 demoTest 方法
    num = 93989834  # 长整型
    result_demoTest = unary_service_stub.get_demoTest(num)
    print(result_demoTest)

What you expected to happen

i want to know what's going on? can provide more simple demos? it's very hard to use. there are so many mirror bug of the document...
