Spring cloud Spring cloud Ribbon Zookeeper中的自定义LoadBlancher规则

在使用ribbon zookeeper discovery设置自定义负载平衡器规则时遇到问题，当前的规则提供程序是循环的、随机的和粘性的，但是我想要自定义规则。无法对其进行自定义，因此尝试覆盖

ZookeeperRibbonClientConfiguration

的bean

dependenciesBasedLoadBalancer

，当我尝试覆盖该bean时，出现以下错误

Description:

Parameter 1 of method dependenciesBasedLoadBalancer in io.github.kprasad99.consumer.MasterZookeeperRibbonAutoConfiguration required a bean of type 'com.netflix.loadbalancer.ServerList' that could not be found.


Action:

Consider defining a bean of type 'com.netflix.loadbalancer.ServerList' in your configuration.

Description:

Parameter 0 of method ribbonServerListFromDependencies in io.github.kprasad99.consumer.MasterZookeeperRibbonAutoConfiguration required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.


Action:

Consider defining a bean of type 'com.netflix.client.config.IClientConfig' in your configuration.

因此，我尝试复制整个文件

ZookeeperRibbonAutoConfiguration

并自定义

depdensciesbaseloadbalancer

，结果出现以下错误

Description:

Parameter 1 of method dependenciesBasedLoadBalancer in io.github.kprasad99.consumer.MasterZookeeperRibbonAutoConfiguration required a bean of type 'com.netflix.loadbalancer.ServerList' that could not be found.


Action:

Consider defining a bean of type 'com.netflix.loadbalancer.ServerList' in your configuration.

Description:

Parameter 0 of method ribbonServerListFromDependencies in io.github.kprasad99.consumer.MasterZookeeperRibbonAutoConfiguration required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.


Action:

Consider defining a bean of type 'com.netflix.client.config.IClientConfig' in your configuration.

为了解决IClientConfig问题，我尝试从

DefaultClientConfigImpl

创建一个ICleanConfig类型的bean，结果出现了错误
