whats the dubbo version? you use XML config or spring boot starter?

[JemyXiao]

whats the dubbo version? you use XML config or spring boot starter?

dubbo version is 2.6.0 i use springboot starter ver=2.0.0

[KevinClair]

Please show us your dubbo service interface

[JemyXiao]

Please show us your dubbo service interface

[JemyXiao]

i debug application start process, i find registerServiceBean not in,i am not sure because of that

[KevinClair]

May be you have to make sure that your dubbo service has been registed successfully.

[yu199195]

@KevinClair i think it the dubbo-spring-boot-starter , not register spring bean, can you fix it？

[JemyXiao]

May be you have to make sure that your dubbo service has been registed successfully.

i am sure dubbo service registed successful already.

[KevinClair]

@KevinClair i think it the dubbo-spring-boot-starter , not register spring bean, can you fix it？

ok. i will fix it.

[JemyXiao]

@KevinClair i find another problem, i try registry ServiceBean successful,but when invoke AlibabaDubboServiceBeanListener handler method,line 101 method.getAnnotation(ShenyuDubboCilent.Class) is null. please look it together,thanks.

Got it.

[yu199195]

I think dubbo proxy bean maybe miss the annotation, if use dubbo annotation type..

[JemyXiao]

I think dubbo proxy bean maybe miss the annotation, if use dubbo annotation type..

i agree with you, i hope it can be fixed together?

[KevinClair]

Hello @JemyXiao ,I've tried many times and it's all successful.Here are some of my configuration.

And when I run my application.

[yu199195]

@KevinClair He not use XML， used Annotation.....

[KevinClair]

@KevinClair He not use XML， used Annotation.....

Sorry, I run application with Annotation, It works as well.

[JemyXiao]

please show detail your dubbo service impl

[JemyXiao]

@KevinClair please remove dubbo config xml,retry add @Service dubbo Annotation

[JemyXiao]

[KevinClair]

@KevinClair please remove dubbo config xml,retry add @service dubbo Annotation

I try it and works as well.

@KevinClair Hi, @Services is Dubbo Annotaion, not spring

[JemyXiao]

@KevinClair please remove dubbo config xml,retry add @service dubbo Annotation

I try it and works as well.

in think your xml not remove

[KevinClair]

Hello @JemyXiao , if you can, please send your simple example to my emil kevinclair@apache.org so that we can check the problem.

[JemyXiao]

Hello @JemyXiao , if you can, please send your simple example to my emil kevinclair@apache.org so that we can check the problem.

i use shenyu-examples-alibaba-dubbo-service module, i edit DubboTestServiceImpl use dubbo @Service Annotation, u can try it

Got it.

[KevinClair]

Hello @JemyXiao , I have found problem, you have to add @DubboComponentScan({"org.apache.shenyu.examples.alibaba.dubbo.service.impl"}) in the org.apache.shenyu.examples.alibaba.dubbo.service.TestAlibabaDubboApplication to make sure Dubbo scan your interface with @Service, just like this:

• TestAlibabaDubboApplication

  
  @SpringBootApplication
  @ImportResource({"classpath:spring-dubbo.xml"})
  @DubboComponentScan({"org.apache.shenyu.examples.alibaba.dubbo.service.impl"})
  public class TestAlibabaDubboApplication {
  
  /**
   * Main Entrance.
   *
   * @param args startup arguments
   */
  public static void main(final String[] args) {
      SpringApplication.run(TestAlibabaDubboApplication.class, args);
  }

}

* DubboTestServiceImpl 
```java
package org.apache.shenyu.examples.alibaba.dubbo.service.impl;

import java.util.Arrays;
import java.util.Random;

import com.alibaba.dubbo.config.annotation.Service;
import org.apache.shenyu.client.dubbo.common.annotation.ShenyuDubboClient;
import org.apache.shenyu.examples.dubbo.api.entity.DubboTest;
import org.apache.shenyu.examples.dubbo.api.entity.ListResp;
import org.apache.shenyu.examples.dubbo.api.service.DubboTestService;
import org.springframework.stereotype.Component;

/**
 * DubboTestServiceImpl.
 */
@Component("dubboTestService")
@Service
public class DubboTestServiceImpl implements DubboTestService {

@Override
    @ShenyuDubboClient(path = "/findById", desc = "Query by Id")
    public DubboTest findById(final String id) {
        DubboTest dubboTest = new DubboTest();
        dubboTest.setId(id);
        dubboTest.setName("hello world shenyu Alibaba Dubbo, findById");
        return dubboTest;
    }
}

• spring-dubbo.xml

  
  <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans.xsd
     http://code.alibabatech.com/schema/dubbo
     http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
  
  <dubbo:application name="test-dubbo-service"/>
  
  <dubbo:registry address="zookeeper://localhost:2181"/>
  
  <dubbo:protocol name="dubbo" port="20888"/>

// you can also use this.

* if you delete spring-dubbo.xml, you have to add configuration in the application.yml and add `@EnableDubbo` in `TestAlibabaDubboApplication`, for example:
```java
@SpringBootApplication
@EnableDubbo
public class TestAlibabaDubboApplication {

    /**
     * Main Entrance.
     *
     * @param args startup arguments
     */
    public static void main(final String[] args) {
        SpringApplication.run(TestAlibabaDubboApplication.class, args);
    }

}

dubbo:
  application:
    name: demo-service
  registry:
    protocol: zookeeper
    address: localhost:2181
  protocol:
    name: dubbo
    port: 20880
  scan:
    base-packages: org.apache.shenyu.examples.alibaba.dubbo.service.impl

@KevinClair thanks for patiently answer, i try it successfull follow your way. about another problem not found @ShenyuXXXClient Annotation from impl class, i fix it and pull request also.

[KevinClair]

@KevinClair thanks for patiently answer, i try it successfull follow your way. about another problem not found @ShenyuXXXClient Annotation from impl class, i fix it and pull request also.

But if you follow my way, @ShenyuXXXClient would be found.

[JemyXiao]

@KevinClair thanks for patiently answer, i try it successfull follow your way. about another problem not found @ShenyuXXXClient Annotation from impl class, i fix it and pull request also.

But if you follow my way, @ShenyuXXXClient would be found.

The scene is like this，I run my project not shenyu-example,my impl class generate spring proxy, so when handler method AopUtils.isCglibProxy() param type has a problem, i had pr. please code review my pr code
