Zuul 和 Consul 整合问题

Question

我在使用 Zuul 和 Consul 服务发现设置 Spring 云应用程序时遇到问题。我安装了 Consul 服务器代理并在本地运行ning:

./src/main/bash/local_run_consul.sh

当我运行 Spring 使用 @EnableZuulProxy 注释启动应用程序时，我收到以下错误：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.netflix.zuul.filters.RouteLocator]: Factory method 'routeLocator' threw exception; nested exception is java.lang.IllegalStateException: Unable to locate service in consul agent: edge-server-8765
    at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:189)

ZuulApplication.java

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class ZuulApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(ZuulApplication.class).web(true).run(args);
    }
}

注意： 当我注释掉 @EnableZuulProxy 注释时，我的服务运行没有问题并且在 Consul 中正确注册。

我不知道该怎么办。也许存在一些不良的依赖性问题？

提前致谢。

Answer 1

spring-cloud-consul 中有一个 bug 和 ConsulDiscoveryClient.getLocalServiceInstance。

设置zuul.ignoreLocalService: false暂时可以解决这个问题。
