如何在资源包含从Java到FHIR api的多个参考资源的情况下形成发布请求主体

如何解决如何在资源包含从Java到FHIR api的多个参考资源的情况下形成发布请求主体

我必须将请求正文作为org.hl7.fhir.r4.model.CoverageEligibilityRequest发送，其中包含以下患者，执业者，组织。该API将返回Bundle响应。我正在使用Hapi Fire库中的Java和通用客户端。有提供通过搜索参数的规定，但是这里我具有资源的多层次结构和输入比平常大。谁能帮助我在FHIR API中处理此请求。

请求正文如下

{
      "resourceType": "CoverageEligibilityRequest","contained": [
        {
          "resourceType": "Patient","id": "1","name": [
            {
              "family": "abcFamily","given": [
                "abcGiven"
              ]
            }
          ],"birthDate": "1962-08-06"
        },{
          "resourceType": "Practitioner","id": "2","identifier": [

                  }
                ]
              },"value": "123456789"
            }
          ],"name": [
            {
              "family": "pqrFamily","given": [
                "pqrGiven"
              ]
            }
          ]
        },{
          "resourceType": "Organization","id": "3","identifier": [
            {
              "value": "12345"
            }
          ],"name": ""
        },{

                ]
              },"value": ""
            }
          ]
        }
      ],"extension": [
