无法提取响应：找不到适合响应类型的 HttpMessageConverter

Question

我们正在实施微服务架构。

我已经在外部 tomcat 服务器（即 tomcat9）中部署了 eureka 服务器作为上下文路径“barpp-serviceregistry”

当我从客户端连接时，我们收到以下错误

2022-12-22 08:18:55.863  INFO 1460 --- [freshExecutor-0] c.n.d.s.t.d.RedirectingEurekaHttpClient  : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:9090/barapp-serviceregistry/}, exception=Could not extract response: no suitable HttpMessageConverter found for response type [class org.springframework.cloud.netflix.eureka.http.EurekaApplications] and content type [text/html;charset=utf-8] stacktrace=org.springframework.web.client.UnknownContentTypeException: Could not extract response: no suitable HttpMessageConverter found for response type [class org.springframework.cloud.netflix.eureka.http.EurekaApplications] and content type [text/html;charset=utf-8]

我们作为独立应用程序运行的代码相同，它工作得很好。部署到外部tomcat时是否需要任何配置，我在这里缺少什么？

以下是属性配置

尤里卡服务器

spring:
  application:
    name: barapp-serviceregistry
#server:
#  port: ${port:8761}
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://localhost:9090/barpp-serviceregistry/

尤里卡客户端

eureka:
  client:
    service-url:
      defaultZone: http://localhost:9090/barapp-serviceregistry/

请帮忙解决
