### Steps to reproduce this issue
I just using @Reference to invoke the remote service,but the boot program was

It look like that interface inject failed,what is this guy called 'proxy0'
There is the code about the interface and dubboConfig as follow:
```
public interface ProxyPoolService {
public Map<String,String> poolStatus();
public Boolean loadProxyIPFromFile(String filePath);
}
public class IPService {
@Reference(loadbalance="serviceUrl",check=false,lazy=true)
private ProxyPoolService proxyPoolService;
@Autowired
private ZookeeperUtil zkUtil;
}
provider config:
@Configuration
@Slf4j
public class DubboConfiguration {
@Value("${crawler.provider.num}")
private String providerNum;
@Value("${crawler.zookeeper.address}")
private String zkAddress;
@Value("${crawler.dubbo.protocol.port}")
private Integer protocolPort;
@Bean
public ApplicationConfig applicationConfig() {
ApplicationConfig applicationConfig = new ApplicationConfig();
String localIP="127.0.0.1";
try {
localIP=CommonUtil.getLocalIP();
}catch (Exception e) {
log.error("error in getLocalIP:",e);
}
applicationConfig.setName("tianyanchaCrawler-"+localIP+"-"+providerNum);
return applicationConfig;
}
@Bean
public ConfigCenterConfig configCenterConfig() {
ConfigCenterConfig configCenterConfig=new ConfigCenterConfig();
configCenterConfig.setAddress("zookeeper://"+zkAddress);
return configCenterConfig;
}
@Bean
public MetadataReportConfig metadataReportConfig() {
MetadataReportConfig config=new MetadataReportConfig();
config.setAddress("zookeeper://"+zkAddress);
return config;
}
@Bean
public RegistryConfig registryConfig() {
RegistryConfig registryConfig = new RegistryConfig();
registryConfig.setAddress("zookeeper://"+zkAddress);
registryConfig.setClient("curator");
return registryConfig;
}
@Bean
public ProtocolConfig protocolConfig() {
ProtocolConfig protocolConfig=new ProtocolConfig();
protocolConfig.setPort(protocolPort);
return protocolConfig;
}
}
consumer config:
@Configuration
@Slf4j
public class DubboConfiguration {
@Value("${monitor.provider.num}")
private String providerNum;
@Value("${monitor.zookeeper.address}")
private String zkAddress;
@Bean
public ApplicationConfig applicationConfig() {
ApplicationConfig applicationConfig = new ApplicationConfig();
String localIP="127.0.0.1";
try {
localIP=CommonUtil.getLocalIP();
}catch (Exception e) {
log.error("error in getLocalIP:",e);
}
applicationConfig.setName("tianyanchaCrawler-"+localIP+"-"+providerNum);
return applicationConfig;
}
@Bean
public RegistryConfig registryConfig() {
RegistryConfig registryConfig = new RegistryConfig();
registryConfig.setAddress("zookeeper://"+zkAddress);
registryConfig.setClient("curator");
return registryConfig;
}
}
