Spring Cloud Config Eureka 服务器发现和 zuul

Question

I'm trying to setup a simple microservice architecture based on Spring functionalities.我正在尝试基于 Spring 功能设置一个简单的微服务架构。 I have 3 simple microservices as starting point: 1 Configuration Server (Spring cloud config) 2 Discovery Server (eureka server) 3 Gateway Zuul我有 3 个简单的微服务作为起点：1 配置服务器（Spring 云配置）2 发现服务器（eureka 服务器）3 网关 Zuul

I configure the services so that the discovery server store all the .properties file, it register itself to the discovery server so all other services retrieve the .properties file accessing the discovery not via static url but via eureka server.我配置服务，以便发现服务器存储所有 .properties 文件，它将自己注册到发现服务器，以便所有其他服务检索 .properties 文件，而不是通过静态 url 而是通过 eureka 服务器访问发现。

My problem is, eureka-server has in the bootstrap.properties file the static url of the discovery and it can retrieve the file succesfully but the gateway didn't retrieve the file from the server.我的问题是，eureka-server 在 bootstrap.properties 文件中有发现的静态 url，它可以成功检索文件，但网关没有从服务器检索文件。 I have a the following error:我有以下错误：

2020-03-24 16:49:32.287  INFO 43460 --- [  restartedMain] c.c.c.ConfigServicePropertySourceLocator : Connect Timeout Exception on Url - http://host.docker.internal:8081/. Will be trying the next url if available
2020-03-24 16:49:32.289  WARN 43460 --- [  restartedMain] c.c.c.ConfigServicePropertySourceLocator : Could not locate PropertySource: I/O error on GET request for "http://host.docker.internal:8081/gateway/default": connect timed out; nested exception is java.net.SocketTimeoutException: connect timed out

My configuration for the services is the following:我的服务配置如下：

config :配置：

application.properties:应用程序属性：

server.port=8081
spring.application.name=config

spring.cloud.config.server.git.uri=file:///${user.home}/application-config

eureka.client.region = default
eureka.client.registryFetchIntervalSeconds = 5
eureka.client.serviceUrl.defaultZone=http://localhost:8082/eureka/

The strange thing is that if after I start everything I try to access the gateway file from the browser calling http://host.docker.internal:8081/gateway/default I can retrieve the file but when the gateway starts he tries to retrieve the same file and It gaves my the error above:奇怪的是，如果在我开始一切之后我尝试从浏览器访问网关文件调用http://host.docker.internal:8081/gateway/default我可以检索文件但是当网关启动时他试图检索同一个文件，它给了我上面的错误：

Can anyone help me please?有人可以帮我吗？

Answer 1

If someone has my same problem I found the solution.如果有人遇到我同样的问题，我找到了解决方案。 It was due to my host file.这是由于我的主机文件。 I changed it once to fit with a VPN I worked and it map my ip with an ip I can't reach without the VPN on.我对其进行了一次更改以适应我工作的 VPN，并且它将我的 ip 映射到一个我无法在没有 VPN 的情况下访问的 ip。 Once I comment the file host everything works一旦我评论文件主机一切正常
