Springboot Unable to register client applications to the Eureka server with custom context path

问题

我在Eureka服务器应用程序配置中未指定server.servlet.context-path值时，能够在Eureka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，就无法在Eureka服务器中注册客户端应用程序，而且始终会收到404错误。如果有人能帮忙查看并指导我漏掉了什么，将会非常有帮助。我找到了一些与此错误相关的Stack Overflow帖子，但它们大多是关于旧版本的Spring Boot，我尝试了一些，但没有帮助。我的Spring版本是2.2.6。

请查看下面的配置，

Eureka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/

异常详细信息如下，

（以下为一系列日志，描述了Eureka客户端的初始化和注册过程，以及发生的错误）

I was able to register the client application in the eureka server when i didnt specify server.servlet.context-path value in eureka server application configuration. But, when i changed the server.servlet.context-path to some value, then unable to register a client application in Eureka server and im always getting an error 404. If someone please have a look and guide me on what im missing that would be of great help. I have found few SO related to this error but mostly they are with old versions of spring boot and i tried few but doesnt help. My spring version is 2.2.6

Please see my configuration below,

Eureka server configuration

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

Client configuration

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/
