dubbo问题

1.dubbo启动异常，提供者未暴露服务

provider未提供配置
Related cause: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loanQuotaRecoverOrdersInterface':
Cannot resolve reference to bean '0' while setting bean property 'registry'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No bean named '0' is defined
新增接口添加provider

没有扫描到loanQuotaRecoverOrdersInterfaceImpl服务：实现类没有添加注解
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.qsc.loan.service.LoanQuotaRecoverOrdersInterface': Cannot resolve reference to bean 'loanQuotaRecoverOrdersInterfaceImpl' while setting bean property 'ref'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'loanQuotaRecoverOrdersInterfaceImpl' is defined

2.调用本地dubbo服务：

url="dubbo://127.0.0.1:20552"

3.dubbo启动，zookeeper内存不足，导致启动失败
