我们有一个Web服务A（Java 17，spring-cloud-starter-openfeign: 3.1.6，spring-cloud-starter-netflix-eureka-client: 3.1.6，testcontainers: 1.18.0，wiremock: 2.35.0），它使用openfeign调用服务B。由于服务B在Eureka 中注册，因此我们使用下面的openfeign客户端向B服务发送调用：

@FeignClient("SESSION-MANAGER")
public interface SessionManagerClient {

    @PostMapping(path = "/session/get", consumes = "application/json")
    Session getSession(SessionRequstBody sessionRequstBody);

}

Openfeign配置（* 我们没有任何其他openfeign配置或beans*）：

feign:
  client:
    config:
      default:
        connectTimeout: 600000
        readTimeout: 600000
        logger-level: basic

这段代码通过SESSION-MANAGER名称在Eureka 中找到相应的服务并发送请求。它在环境中运行良好。但是我不太明白如何在集成测试中模拟这个/session/get调用（使用wiremock）。因为在代码调用和openfeign客户端之间存在Eureka （隐式）。因此，由于它openfeign认为@FeignClient("SESSION-MANAGER")作为主机，并发送这样的请求http://SESSION-MANAGER/session/get导致此错误：

问题是你能帮我理解在这种情况下我应该嘲笑什么吗？我是否应该直接模拟对服务B的调用，或者我甚至应该在Testcontainers中升级Eureka 并在这个级别上管理它？
Eureka 配置：

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: true
    healthcheck:
      enabled: false
    serviceUrl:
      defaultZone: "http://localhost:8761/eureka/"
  instance:
    statusPageUrl: "http://${eureka.hostname}/info"
    healthCheckUrl: "http://${eureka.hostname}/health"
    homePageUrl: "http://${eureka.hostname}/"
    nonSecurePortEnabled: true

Wiremock：

WIREMOCK_SERVER.stubFor(WireMock.post(WireMock.urlPathEqualTo("/session/get"))
        .withRequestBody(WireMock.equalToJson(TELEGRAM_SESSION_MANAGER_LEASED_SESSION_REQUEST_BODY))
        .willReturn(WireMock.aResponse()
            .withStatus(200)
            .withHeader("Content-Type", "application/json")
            .withBody(TELEGRAM_SESSION_MANAGER_LEASED_SESSION_RESPONSE))
);
