java - 带有微服务的 Spring REST 应用程序

标签 java spring spring-boot consul netflix-feign

我得到的这个 Spring Boot 应用程序现在无法在开发模式下独立运行。它被配置为使用 Consul 作为服务发现。它在 Docker 容器和 Consul 容器(名为“consul-master”)中工作得很好，但是当我从 IDE 运行时它不会启动:

为了让它在开发模式下运行(“dev”配置文件 --spring.profiles.active=dev)，我使用了以下配置(bootstrap-dev. yml):

spring:
  cloud:
    consul:
      enabled: false

结果是一个异常，我真的不知道如何修复:

除此之外，我什至尝试在 application.yml 上为 FeignClient 手动设置服务器列表:

integrationmicro:
  ribbon:
    listOfServers: 192.168.0.13:8001

bootstrap.yml

spring:
  cloud:
    consul:
      discovery:
        instanceId: ${spring.application.name}:${vcap.application.instance_id:${spring.application.instance_id:${random.value}}}
        healthCheckPath: /health
      host: consul-master
      port: 8500

最佳答案

当您使用 docker 和 consul 运行您的服务时，它会注册到 consul，因为它在 docker-compose.yml 文件中有它的条目并且会发生注册部分，但我们并没有完全看到。所以您不会遇到任何问题，但是当您通过 IDE 运行它时，您没有向 consul 注册它，因此它会抛出 UnknownHostException。

基本上您需要注册您的服务以发现它。

我是用下面的命令做的，

curl -X PUT -H 'application/json' -d '{"Node": "yourServiceName", "Address":"yourHost.com", "Service": {"Service": "yourServiceName ", "标签": ["代理"], "端口": 8080}}' http://yourHost/v1/catalog/register

注意:

1.提及正确的端口和名称。

2.从存在 docker-compose.yml 的位置运行上述命令

也可以引用Consul Getting Started和 Consul Catalog API获得有关将本地运行的服务注册到 consul 的帮助，因为上述命令特定于我的要求，可能不适合您的要求。

希望对您有所帮助!
