Olingo-OData：如何在Olingo OData中定义复杂类型

Question

我需要在OData实体的JSON下面定义。

"d" : {
    "__metadata" : {
      "type" : "ServiceCloudAssetModel.HBServicesInfo",
      "uri" : "http://sdf.com/notimplemented/Entity(0)"
    },
    "SPVersion" : "0",
    "Status" : "Informational",
    "ResponseCode" : "100",
    "Description" : "High Memory Usage; Hardware Failure detected",
    "LastBootUpDate" : "2017-04-07T20:48:13.486816",
    "SchemaVersion" : null,
    "AgentVersion" : "2.0.0.0",
    "WindowsUpdatedRunDate" : "2017-04-05T08:13:42",
    "UTCDate" : "2018-06-20T18:22:32.3388283Z",
    "ResponseMessage" : "Success",
    "uuid" : "bada16db-2b2f-46de-a366-545ea9774d2c",
    "LocalDate" : "2018-06-10T23:52:32.3970051+05:30",
    "URL" : "https://uat.sdf.com/#/xyz/devices/heartbeat/XYZ$$9223370507383975807",
    "SystemDriveFreeSpace" : "110.29 GB",
    "HighCPUUsage" : "60",
    "Model" : "ABCE7440",
    "ApplicationCrashesLast24hrs" : null,
    "OSVersion" : "6.3.9600",
    "BIOSVersion" : "A08",
    "ServiceTagId" : "XYZ",
    "Registered" : "false",
    "HighMemUsage" : "87.5"
  }

我已经为简单类型编写了以下getEntityType函数...我需要的是定义__metadata和d复杂类型的帮助。

    @Override
    public CsdlEntityType getEntityType() {
    // create CsdlPropertyRef for Key element
                CsdlEntityType entityType = new CsdlEntityType();
                entityType.setName(ET_HeartBeatData);
                CsdlPropertyRef propertyRef = new CsdlPropertyRef();
                propertyRef.setName(ETF_SERVICETAGID);              
                List<CsdlPropertyRef> csdlPropertyRefList = new ArrayList<CsdlPropertyRef>();
                csdlPropertyRefList.add(propertyRef);               
                entityType.setKey(csdlPropertyRefList);


    // create EntityType properties
