Spring 微服务实例未向在 8761 以外的端口中运行的 Eureka 注册

【中文标题】Spring 微服务实例未向在 8761 以外的端口中运行的 Eureka 注册【英文标题】:Spring microservice instance is not registering with Eureka running in port other than 8761 【发布时间】:2019-08-11 05:16:53 【问题描述】:我的微服务的application.yml(Eureka 的客户端)
spring:
application:
name: queue1
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8762/
server:
port: 7777
app:
id: $random.uuid
尤里卡的application.yml
eureka:
instance:
hostname: peer1
client:
register-with-eureka: false
fetch-registry: false
server:
port: 8762
我正在端口 8762 中启动 Eureka,并在我的微服务中引用它。 微服务无法向 Eureka 注册。 以下是微服务日志中的异常。

现在最重要的是,如果我将Eureka服务器端口和微服务的Eureka注册端口更改为8761,一切都很好!!!!本例微服务注册成功。
在发布问题之前多次执行此操作,它的行为是这样的。
这里的任何输入都会非常有帮助。
【问题讨论】:
我使用的springboot版本是2.1.3.RELEASE。和云版本:Greenwich.RELEASE 我有 defaultZone: localhost:8761/eureka 也许试试 defaultZone: localhost:8762/eureka ? 这行得通! defaultZone 属性中应该有 eureka。非常感谢马克思...... 没有让它更清楚。 defaultZone 应该是“localhost:8762/eureka”而不是“localhost:8762”。当使用端口 8761 并且 defaultZone 值为“localhost:8761”时 - 注册工作正常。在这种情况下,我猜,在内部,eureka 使用 url "localhost:8761/eureka" 而不是属性文件 "localhost:8761" 中给出的内容 /eureka 对我有用,但并非在所有情况下。我有一个 Spring Boot 模块版本 2.1.5 与 localhost:9100 工作正常,另一个需要 localhost:9100/eureka 的 Spring Boot 版本 2.1.3 否则会引发相同的 MismatchedInputException 错误 【参考方案1】:我遇到了同样的问题,这是由于 Eureka 服务器项目中的 spring 安全依赖项。将@EnableWebSecurity 代码添加到为我修复的eureka 服务器应用程序之后。
@EnableWebSecurity
static class WebSecurityConfig extends WebSecurityConfigurerAdapter
@Override
protected void configure(HttpSecurity http) throws Exception
http.csrf().disable();
Spring Boot 版本 - 2.3.2.RELEASE Spring Cloud 版本 - Hoxton.SR1 https://github.com/spring-cloud/spring-cloud-netflix/issues/2754#issuecomment-372808529
