背景：
我有一个简单的Spring Boot应用程序，其中包含三个服务。服务通过HTTP REST调用进行通信。以下是对服务的简要说明。
任务计划器（localhost:9100）
/v1/missionServices/missionPlanning/planMission）触发。一个简单的响应消息返回给调用者。路由生成器（localhost:9110）
/v1/missionServices/missionPlanning/generateRoute）调用时生成“路线”。向任务计划者返回响应消息。路由评估器（localhost:9120）
/v1/missionServices/missionPlanning/assessRoute）调用时评估生成的“路线”。向任务计划者返回响应消息。任务计划者“客户端”是通过向任务计划者发送POST请求来触发“计划任务”过程的第四项服务。这不是集成测试的一部分。相反，使用Citrus测试。
目标：
我正在尝试使用Citrus框架对服务进行单独或整体（端到端）的集成测试。对于较简单的服务案例（即路线生成器和路线评估器），我已经取得了成功，但事实证明，测试任务计划程序存在许多困难。
下面是我为任务计划者编写的Citrus测试。目前，我正在“模拟”路由生成器和路由评估器服务，但是对于端到端测试，将需要弄清楚如何做到这三个服务都将“生效”-我现在不必担心。我基于发现的示例以及从我的经验中学到的知识来构建它。
MissionPlannerIT.java：
public class MissionPlannerIT extends JUnit4CitrusTest {

@Qualifier("routeGeneratorServer")
private HttpServer rgServer;

runner.description("Test mission planning 'plan mission' REST endpoint");
// Call mission planner to plan a mission.
runner.http(builder -> builder

// Shut down route services. TODO may not need this

EndpointConfig.java：
@Configuration
public class EndpointConfig {
@Bean
public HttpClient missionPlannerClient() {
return CitrusEndpoints.http().client().requestUrl("http://localhost:9100").build();
}
@Bean
public Server routeGeneratorServer() {
return CitrusEndpoints.http().server().port(9110).timeout(10000).autoStart(true).build();
}
@Bean
public Server routeAssessorServer() {
return CitrusEndpoints.http().server().port(9120).timeout(10000).autoStart(true).build();
}
@Bean("defaultJsonMessageValidator")
public JsonTextMessageValidator jsonValidator() {
return new JsonTextMessageValidator();
}
}
我有两种方法运行此测试：1）作为Maven构建的一部分，以及2）使用eclipse。将其作为Maven构建运行时遇到问题，其中大多数测试控制台的输出均未输出（请参阅Citrus Framework logging - how to enable/use和Citrus Framework - echo action does not "echo"）。当我通过Eclipse运行它时，我需要在运行测试之前手动启动任务计划程序。
输出：
我包括了Eclipse运行方法中的部分控制台日志，因为它包含使用maven方法时丢失的信息。我将尝试包括我认为相关的部分，并一路包括我的笔记/想法。

想法：
SUT（任务计划程序服务）与模拟生成器之间的交互似乎都按预期工作。消息来回传递，似乎没有问题。我不明白的是HTTP 503错误的外观。它似乎在第一步测试中发生，但我不知道可能是什么错误。
我什至不知道如何尝试调试任何一个。我对HTTP的工作方式并不熟悉。从我的角度来看，很多正在发生的事情在幕后发生，我不知道该怎么看那里发生的事情。
[如果有人在我所做的事情中发现错误，请告诉我。如果有人有什么想法可能会发生什么，那将非常有帮助。最后，非常感谢您提出有关尝试调试的建议。
UPDATE：
我修改了测试，将超时调用添加到客户端和服务器端点。例如：
@Bean
public HttpClient missionPlannerClient() {
return CitrusEndpoints.http().client().requestUrl("http://localhost:9100").timeout(30000).build();
}
不幸的是，这对我的问题没有影响。
我还已将以下内容添加到SUT（任务计划程序）application.yml：
server:
port: 9100
...
jetty:
http:
idleTimeout: 60000
stopTimeout: 60000
connection-idle-timeout: 60000
thread-idle-timeout: 60000
这似乎也没有影响。我不确定100％是否使用了正确的属性。
NOTE：
我进行了一个有趣的实验，该实验不涉及Citrus，但是我在其中运行了所有三个真实服务，然后尝试通过Postman进行“计划任务”调用。我得到了相同的HTTP 503响应。
现在事实证明，真正的“路由”服务具有内置的可配置延迟，可以模拟长时间运行的任务。每个服务的延迟设置为5秒。
我将这些延迟设置为0，然后再次与Postman一起发布。这次成功了！我假设Postman具有默认超时，并且服务延迟超过了该时间，从而导致观察到的结果。也许？我想我会收到某种超时消息，而不是“服务不可用”。
延迟肯定会对该测试结果产生影响，但是，在Citrus测试案例中，“路由”服务正在被嘲笑，不应引入任何人为延迟。
只是一个有趣的观察。
[您在Http客户端发送初始请求的第一个测试步骤中缺少fork=true。 Http本质上是一种同步协议，这意味着测试的第一步将等待Http响应，然后再继续其他测试步骤。这意味着未执行所有其他测试步骤，因此您的Http服务器模拟将无法正常运行。
我猜您因此会在客户端和Http服务器端都遇到很多请求超时。这可能会导致Http 503。
