Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo java 3.3.4 , jdk 8 , macos

Steps to reproduce this issue

I defined the service using triple-rest SpringMVC, and I had an error simulating rpc call injection

@RequestMapping("/test")
public interface TestService {

    @GetMapping(value = "/sayHello")
    String sayHello(@RequestParam(name = "name") String name);

    @PostMapping(value = "/sayHello2")
    String sayHello2(@RequestBody TestVO testVO);
}

@DubboService
public class TestServiceImpl implements TestService{
    @Override
    public String sayHello(String name) {
        return "hello " + name;
    }

    @Override
    public String sayHello2(TestVO testVO) {
        return testVO.toString();
    }
}

@RequestMapping("/serviceA")
public interface ServiceA {

    @GetMapping("/test")
    void test();
}

@DubboService
public class ServiceAImpl implements ServiceA{

    @DubboReference(scope = "remote")
    private TestService testService;

    @Override
    public void test() {
        System.out.println(testService.sayHello("service A"));
    }
}


org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'testService' method
