Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

• Dubbo Version: 3.3.0

• APISIX Version: Unknown (tested with HTTP/1.1 enabled)

• JDK Version: 1.8.0_452

• Framework: Spring Boot 2.7.18

• Protocol: Triple (tri)

Steps to reproduce this issue

step1: Deploy APISIX Gateway and configure service discovery via Nacos Follow the official documentation to deploy APISIX and complete service discovery with Nacos: https://cn.dubbo.apache.org/zh-cn/blog/2024/04/22/%E4%BD%BF%E7%94%A8-apache-apisix-%E4%BB%A3%E7%90%86-dubbo-%E6%9C%8D%E5%8A%A1triple%E5%8D%8F%E8%AE%AE/ Key configurations:

• APISIX listens on 10.216.23.40:8090.
• Route rule: Proxy requests to /com.example.edu.initializer.samples.dubbo3.DemoService/* to the backend Dubbo Triple service (discovered via Nacos).

step2: Verify APISIX proxy works via curl Execute the following curl command and get a successful response:

curl http://10.216.23.40:8090/com.example.edu.initializer.samples.dubbo3.DemoService/sayHello -i

Curl response (successful):

HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: 12
Connection: keep-alive
alt-svc: h2=":24395"
Server: APISIX/3.2.2

"Hello null"

step3:Call via @DubboReference annotation and trigger exception Consumer code with @DubboReference:

@DubboReference(
        interfaceClass = DemoService.class,
        protocol = "tri",
        url = "tri://10.216.23.40:8090/com.example.edu.initializer.samples.dubbo3.DemoService/sayHello"
)
private DemoService demoService;

Trigger the call in consumer application:

String result = demoService.sayHello("test");

exception happened：

What you expected to happen

The @DubboReference annotation should correctly send Triple protocol requests (adapted to HTTP/1.1 via configuration) to the APISIX gateway, and successfully receive the response from the backend service.

Anything else

No response
