two consumer beans are created.

[beiwei30]

Hi，
Every one.
I use dubbo spring-boot with

<dependency>
    <groupId>com.alibaba.boot</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>0.2.0</version>
</dependency>

And in order to decouple with dubbo .
I do not use @service (com.alibaba.dubbo.config.annotation.Service) annotation on my serviceImpl class , but add @component annotation to them.
Then I config the service and refrence in another two xml file as

<dubbo:service interface="com.ecms.ecframe.auth.service.EcAuthMenuI18nService" ref="ecAuthMenuI18nServiceImpl" version="0.5.0" protocol="dubbo" timeout="5000"></dubbo:service>    

<dubbo:reference xmlns="" interface="com.ecms.ecframe.auth.service.EcAuthMenuI18nService" version="0.5.0" id="ecAuthMenuI18n"></dubbo:reference>  

to regist the bean to zookeeper as a service.
Finally I use

@ImportResource(locations = {"classpath:META-INF/dubbo/provider.xml"}) 

on the bootstrap class of my springboot application.
Then it works.

But when I config the consumer , a problem happened.
In my application.properties I set a property as
dubbo.consumer.check=false
to skip the exist check of provider
and I need a filter to do some work before a RPC request send,so I configed a filter on my xml file

<dubbo:consumer filter="UserConsumerFilter"/>

when the application start

2019-03-07 15:23:14.672  WARN 4116 --- [           main] o.s.b.f.s.DefaultListableBeanFactory     : Bean creation exception on non-lazy FactoryBean type check: org.springframework.beans.factory.BeanCreationException:  Error creating bean with name 'ecAuthMenuI18n': Invocation of init method failed; nested exception is java.lang.IllegalStateException:  Duplicate consumer configs: <dubbo:consumer generic="false" filter="UserConsumerFilter" id="com.alibaba.dubbo.config.ConsumerConfig" /> and <dubbo:consumer generic="false" />

I think the first tag is from the xml and the secod tag is from the application.properties.

then I try to add a id parameter on my xml file like

<dubbo:consumer filter="UserConsumerFilter" id="aaa"/>

the warn info is :

2019-03-07 16:56:32.498  WARN 6504 --- [           main] o.s.b.f.s.DefaultListableBeanFactory     : Bean creation exception on non-lazy FactoryBean type check: org.springframework.beans.factory.BeanCreationException:  Error creating bean with name 'ecAuthMenuI18n': Invocation of init method failed; nested exception is java.lang.IllegalStateException:  Duplicate consumer configs: <dubbo:consumer generic="false" filter="UserConsumerFilter" id="aaa" /> and <dubbo:consumer generic="false" />

So I think dubbo can only config one <dubbo:consumer > in a context.

Can we consider to imporve this in the future ?

我们在使用dubbo的过程中，希望可以很容易的在rpc模式和本地模式之间切换，所以并没有使用dubbo的@service注解和@refrence注解。而是使用@component注解将service的实现类注册到spring
再用额外的xml分别定义dubbo的service和refrence

<dubbo:service interface="com.ecms.ecframe.auth.service.EcAuthMenuI18nService" ref="ecAuthMenuI18nServiceImpl" version="0.5.0" protocol="dubbo" timeout="5000"></dubbo:service>    

<dubbo:reference xmlns="" interface="com.ecms.ecframe.auth.service.EcAuthMenuI18nService" version="0.5.0" id="ecAuthMenuI18n"></dubbo:reference>  

在springboot的启动类中分别引入consumer和provider的xml配置。
现在我需要在consumer端加一个filter，于是，我在xml中增加了

<dubbo:consumer filter="UserConsumerFilter"/>

由于原来在application.properties中指定了
dubbo.consumer.check=false

启动报错：

2019-03-07 15:23:14.672  WARN 4116 --- [           main] o.s.b.f.s.DefaultListableBeanFactory     : Bean creation exception on non-lazy FactoryBean type check: org.springframework.beans.factory.BeanCreationException:  Error creating bean with name 'ecAuthMenuI18n': Invocation of init method failed; nested exception is java.lang.IllegalStateException:  Duplicate consumer configs: <dubbo:consumer generic="false" filter="UserConsumerFilter" id="com.alibaba.dubbo.config.ConsumerConfig" /> and <dubbo:consumer generic="false" />

xml中的标签加了个id

<dubbo:consumer filter="UserConsumerFilter" id="aaa"/>

报错：

2019-03-07 16:56:32.498  WARN 6504 --- [           main] o.s.b.f.s.DefaultListableBeanFactory     : Bean creation exception on non-lazy FactoryBean type check: org.springframework.beans.factory.BeanCreationException:  Error creating bean with name 'ecAuthMenuI18n': Invocation of init method failed; nested exception is java.lang.IllegalStateException:  Duplicate consumer configs: <dubbo:consumer generic="false" filter="UserConsumerFilter" id="aaa" /> and <dubbo:consumer generic="false" />

我想这个是由于dubbo只能接受一个<dubbo:consumer />配置的原因吗？
这个是否能够作为一个issue提出来，后续加以改进呢？

谢谢。
