Spring microservice实例未向运行在8761以外端口的Eureka注册

我的微服务的application.yml（客户到Eureka）

Eureka的application.yml

eureka:
  instance:
    hostname: peer1
  client:
    register-with-eureka: false
    fetch-registry: false
server:
  port: 8762

我在8762端口启动Eureka，并在我的微服务中引用它。 Microservice未能向Eureka注册。 以下是microservice日志中的例外情况

现在最重要的是，如果我将Eureka服务器端口和microservice的Eureka注册端口更改为8761，一切都会很好！！！！在此情况下，microservice的注册正在成功进行

在发布问题之前多次这样做，结果是这样的

这里的任何输入都会非常有用。

我也有同样的问题，这是由于Eureka服务器项目中的spring安全依赖性造成的。在将@EnableWebSecurity代码添加到eureka服务器应用程序后，我修复了这个问题

    @EnableWebSecurity
   static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable();
        }
    }

我使用的springboot版本是2.1.3.0版本。云版本：Greenwich.release我有defaultZone:也许可以试试defaultZone:？这很有效！defaultZone属性中应该有eureka。非常感谢，马克思……不，说得更清楚些。defaultZone应为“”，而不是“”。当使用端口8761且defaultZone值为“”时，注册工作正常。在本例中，我猜，在内部，eureka使用url“”，而不是在属性文件“”中提供的内容/eureka为我工作，但并非在所有情况下都如此。我有一个springboot模块版本2.1.5可以正常工作，另一个springboot版本2.1.3需要抛出相同的不匹配InputException错误我使用的springboot版本是2.1.3.RELEASE。云版本：Greenwich.release我有defaultZone:也许可以试试defaultZone:？这很有效！defaultZone属性中应该有eureka。非常感谢，马克思……不，说得更清楚些。defaultZone应为“”，而不是“”。当使用端口8761且defaultZone值为“”时，注册工作正常。在本例中，我猜，在内部，eureka使用url“”，而不是在属性文件“”中提供的内容/eureka为我工作，但并非在所有情况下都如此。我有一个2.1.5版的spring引导模块可以正常工作，还有另一个2.1.3版的spring引导模块需要抛出同样的不匹配PutException错误
