feign client 开发环境中只调用本身本地的服务

1.新建一个 TestRibbon 实现 IRule 接口 代码以下：

import com.netflix.loadbalancer.BaseLoadBalancer;
import com.netflix.loadbalancer.ILoadBalancer;
import com.netflix.loadbalancer.IRule;
import com.netflix.loadbalancer.Server;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.List;

public class TestRibbon implements IRule {
    private Logger logger = LoggerFactory.getLogger(TestRibbon.class);

    ILoadBalancer balancer = new BaseLoadBalancer();

    @Override
    public Server choose(Object key) {
        List<Server> allServers = balancer.getAllServers();
        String localIp = "";
        try {
            localIp = InetAddress.getLocalHost().getHostAddress().toString();

        } catch (UnknownHostException e) {
            logger.info("未找到本机ip：", e);
        }

        for (Server server : allServers) {
            if (server.getHost().equalsIgnoreCase(localIp)) {
                logger.info("本次Feign调用地址：host - [{}] Server - [{}]", server.getHost(), server.toString());
                return server;
            }
        }
        return null;

    }

    private Server findServer(List<Server> allServers, int port) {
        for (Server server : allServers) {
            if (server.getPort() == port) {
                return server;
            }
        }
        System.out.println("NULL port=" + port);
        return null;
    }

    @Override
    public void setLoadBalancer(ILoadBalancer lb) {
        this.balancer = lb;
    }

    @Override
    public ILoadBalancer getLoadBalancer() {
        return this.balancer;
    }

 

 

2.application.yml文件中配置新写的Ribbon

 

fund-service-account:
  ribbon:
    NFLoadBalancerRuleClassName: com.xxx.ooo.config.TestRibbon

 

3.这样就只会调用本身本地发布的服务了。
