Answer 4

那把这个加上试试
@Component
public class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor {
    private static final String FEIGN_CONTEXT_BEAN_NAME="feignContext";
    private static final String EUREKA_AUTO_SERVICE_REGISTRATION_BEAN_NAME="eurekaAutoServiceRegistration";    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        if (containsBeanDefinition(beanFactory, FEIGN_CONTEXT_BEAN_NAME, EUREKA_AUTO_SERVICE_REGISTRATION_BEAN_NAME)) {
            BeanDefinition bd = beanFactory.getBeanDefinition(FEIGN_CONTEXT_BEAN_NAME);
            bd.setDependsOn(EUREKA_AUTO_SERVICE_REGISTRATION_BEAN_NAME);
        }
    }    private boolean containsBeanDefinition(ConfigurableListableBeanFactory beanFactory, String... beans) {
        return Arrays.stream(beans).allMatch(b -> beanFactory.containsBeanDefinition(b));
    }}

Answer 6

好像eureka.instance.prefer-ip-address= true这个配置没有生效。
试试添加eureka.instance.hostname属性。

Answer 7

弱弱的问一句这么设置eureka.instance.hostname属性？

Answer 8

你用的是ymleureka：
    instance：
        hostname：如果是xml
eureka.instance.hostname=

Answer 9

试试
eureka.instance.hostname= ${spring.cloud.client.ipAddress}

Answer 10

我现在加了个eureka:
  instance:
    preferIpAddress: true
    hostname: test

Answer 11

eureka:
  instance:
    preferIpAddress: true
    hostname: ${spring.cloud.client.ipAddress}

Answer 12

是你调用其它微服务时出问题了。大概是你的XXXfeign里的getUserPublicKey这个接口方法用到了别的服务。去查看一下这个被调用的服务有没有注册，或是服务是否可用。

Answer 13

特别巧，我昨天和你同一时间遇到了同样的问题，搞的我还以为帖子是我发的 或者我师傅发的！！！解决了吗？我这边发现问题了：调用的那台主机的hostname不能包含下划线，登录服务端机器，sudo vim /etc/hostname，把hostname改了，重启机器，问题解决

Answer 14

eureka服务注册上了么

Answer 15

我之前上线的的项目也这样。feign 使用时 传惨需要加注解，不然编译会报NPE错误的
