尝试重写NamingProxy内的函数时出现java错误[构造函数的参数0]

Question

我试图自定义NamingProxy中的一些函数，这样就可以排除单独的服务器，这些服务器也需要注册到nacos中

但面临一些问题：

***************************
APPLICATION FAILED TO START

Description:

Parameter 0 of constructor in com.gof.springcloud.loadbalancer.CustomNamingProxy required a bean of type 'java.lang.String' that could not be found.

Action:

Consider defining a bean of type 'java.lang.String' in your configuration.

自定义代码如下所示：

自定义代理

public class CustomNamingProxy extends NamingProxy {

    public CustomNamingProxy(String namespaceId, String endpoint, String serverList, Properties properties) {
        super(namespaceId, endpoint, serverList, properties);
    }

    @Override
    public String reqApi(String api, Map<String, String> params, Map<String, String> body, String method)
            throws NacosException {
        return reqApi(api, params, body, getMyServerList(), method);
    }

    private List<String> getMyServerList() {
        // TODO
        return null;
    }
}

SpringBoot应用程序

@SpringBootApplication
@EnableDiscoveryClient
@EnableCaching
@ComponentScan(includeFilters  = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = { NamingProxy.class }) })
public class Gateway9111_App {
    public static void main(String[] args) {
        SpringApplication.run(Gateway9111_App.class, args);
    }

}

您的代码没有返回任何服务列表。首先，填写// TODO行

private List<String> getMyServerList() {
        // TODO
        return null;
}
