功能区负载平衡器客户端未在Spring启动 2.4.3 中禁用

Question

我目前正在为我的实习做一个微服务应用程序，使用Consul进行服务发现，使用feign clients进行服务间的通信。当我们开始使用微服务构建现有项目时，我们将Spring boot升级到了2.4.3

默认情况下，菲恩使用功能区进行负载平衡，但领事已经对传入请求进行了负载平衡。

我们使用spring.cloud.consul.loadbalancer.ribbon.enable禁用了功能区：在我们的配置服务中是错误的，但是我读过一些帖子，使用相同Spring版本的人有类似的问题，并且功能区负载均衡器似乎没有禁用。在Spring启动的github上也声明了一些netflix模块已被删除，因此我认为这与问题有关：https://github.com/spring-cloud/spring-cloud-release/wiki/Spring-Cloud-2020.0-Release-Notes#known-issues 配置服务中的配置正在正确提供，它在日志中是这样说的，我还用一些随机端口对其进行了测试，它们似乎都正确应用了它。将属性放在引导 yaml 中也不起作用。Spring云负载平衡器似乎是功能区的新替代品，但是为了使用它，您需要能够通过前面所述的选项禁用功能区，该选项似乎由于某种原因不起作用。问题是，我们不能在不丢失记录的情况下真正降级，而且我真的没有在任何地方看到修复，或者我可能只是忽略了一些愚蠢的事情。

编辑：从sping-cloud-starter-consul-发现中排除sping-cloud-starter-netfex-ribbon为我们修复了这个问题！

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-consul-discovery</artifactId>
  <exclusions>
    <exclusion>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
    </exclusion>
  </exclusions>
</dependency>
 

Answer 1

您是否可以尝试排除功能区依赖，如下所示

implementation('org.springframework.cloud:spring-cloud-starter-consul-discovery') {
        exclude group: 'org.springframework.cloud', module: 'spring-cloud-starter-netflix-ribbon'
}
