java - Springboot 无法使用自定义上下文路径将客户端应用程序注册到 Eureka 服务器

Question

当我没有在尤里卡服务器应用程序配置中指定 server.servlet.context-path 值时，我能够在尤里卡服务器中注册客户端应用程序。但是，当我将 server.servlet.context-path 更改为某个值时，无法在 Eureka 服务器中注册客户端应用程序，并且我总是收到错误 404。如果有人请看一下并指导我了解我错过了什么有很大帮助。我发现很少有与此错误相关的 SO，但大多数都与旧版本的 spring boot 相关，我尝试了一些但没有帮助。我的春季版本是 2.2.6

请看下面我的配置，

尤里卡服务器配置

spring.application.name = eureka-server
server.port = 8761
server.servlet.context-path=/myeureka
eureka.client.register-with-eureka = false
eureka.client.fetch-registry = false 

客户端配置

spring.application.name = client

server.port=8082
eureka.instance.hostname=localhost
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.service-url.default-zone=http://localhost:8761/myeureka/eureka/
