Return 通过 rest-engine 启动时来自 Camunda 进程的数据

Question

我有一个名为 partnerPortal 的 Camunda 流程。这接受 3 个变量，

{
  "variables": {
    "userId" : {
      "value" : "user1"
  },
    "userName" : {
      "value" : "childProtect"
  },
    "accountType" : {
      "value" : "ideamart"
    }
  }
}

我使用带有端点 "engine-rest/process-definition/key/{processId}/start" 的 Camunda rest-engine 调用此过程使用单独的 spring-boot 应用程序。我的要求是，当进程完成时，我想从 Camunda 引擎 return 数据到外部 spring-boot 应用程序（就像常规 API 调用一样）。

例如，如果我使用 "engine-rest/process-definition/key/partnerPortal/start" 启动流程，我想从 Camunda 接收一个 JSON 数组引擎到 spring-boot 应用程序。
