我按照这些说明运行了 setupdemo 事务（它只是添加了一些示例数据），并成功地添加了一个加速度计读数，该读数针对现有的货物到区块链。装运数据包含加速度计读数：
{
"$class": "org.acme.shipping.perishable.Shipment",
"shipmentId": "320022000251363131363432",
"type": "MEDICINE",
"status": "IN_TRANSIT",
"unitCount": 5000,
"contract": "resource:org.acme.shipping.perishable.Contract#CON_002",
"AccelReadings": [
{
"$class": "org.acme.shipping.perishable.AccelReading",
"accel_x": 4,
"accel_y": 4,
"accel_z": 4,
"latitude": "51",
"longitude": "11",
"readingTime": "2018-11-21T19:40:30.000Z",
"shipment": "resource:org.acme.shipping.perishable.Shipment#320022000251363131363432",
"transactionId": "01aed2c05c78cf638cc68e9bb4ab7428dc7bae212c6409c27049c372f5caee67",
"timestamp": "2018-11-21T18:45:42.497Z"
}
]
}
但是，我在运行 GET /AccelReading 的资源管理器中遇到错误。
