无法测试 UUID

Question

我有一个 spring boot 2.6.7 应用程序，使用 Liquibase、Gradle 和 Spock。我有一个使用 guid 格式字符串作为 ID 的 class：

@Entity
@Table(name = "devices")
public class Device {

    @Id
    @NotNull
    @Pattern(regexp = "^[{]?[0-9a-fA-F]{8}-([0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}[}]?$",
             message = "Invalid id received")
    private String deviceId;

    @NotNull
    private DeviceType deviceType;    
    @JsonFormat(shape = Shape.STRING, pattern = "yyyy-MM-dd")
    private LocalDate manufactureDate;
    @JsonFormat(shape = Shape.STRING, pattern = "yyyy-MM-dd")
    private LocalDate activationDate;
    @JsonFormat(shape = Shape.STRING, pattern = "yyyy-MM-dd")
    private LocalDate deactivationDate;
    private Status deviceStatus;

我有几个端点接受这个实体并persist/find/update它。当我查看数据库时，我看到列已正确填充。所以它似乎有效。

这是我的 liquibase table:

- changeSet:
      id: 7
      preConditions:
        - onFail: MARK_RAN
          not:
            tableExists:
              tableName:
                devices
      changes:
        - createTable:
            tableName: devices
            columns:
                nullable: false
              - column:
                  name: device_id
                  type: varchar(255)
                  constraints:
                    primaryKey: true
                    nullable: false
              - column:
                  name: device_type
                  type: varchar(255)
                  constraints:
                    nullable: true
              - column:
                  name: manufacture_date
                  type: date
                  constraints:
                    nullable: true
              - column:
                  name: activation_date
                  type: date
                  constraints:
                    nullable: true
              - column:
                  name: deactivation_date
                  type: date
                  constraints:
                    nullable: true
              - column:
                  name: internal_id
                  type: varchar(255)
                  constraints:
                    nullable: true
              - column:
                  name: device_status
                  type: varchar(255)
                  constraints:
                    nullable: true

但是，我现在正尝试将我的代码包装在测试中，并且我将运行放入无法将字符串转换为 UUID 的问题中。这是测试：

given:
        def device = new Device(internalId: internalId, deviceId: deviceId,
                deviceType: deviceType, deviceStatus: deviceStatus, role: role, activationDate: activationDate, deactivationDate: deactivationDate, manufactureDate: manufactureDate)

        def result = deviceRepository.save(device)
        when:

        def isValid = deviceServices.validateDevice(result)
        then:
        isValid == testResult

        where:
        deviceId           | deviceType          | deviceStatus       | manufactureDate | activationDate  | deactivationDate | || testResult
        UUID.randomUUID() | DeviceType.EQUIPMENT | Status.ACTIVATED   | LocalDate.now() | LocalDate.now() | null               || true

这是通过尝试插入 H2 开始测试时的错误。该字段声明为 varchar，但由于某种原因，堆栈跟踪提到了 NumberFormat 和 Long 值。

我觉得我没有将主键设为 UUID，或者没有常规 ID 然后将 deviceId 用作 UUID，这让我陷入了困境。但是，这是生产代码，我对通过 Liquibase 更改 table 结构犹豫不决。

有没有办法让 Liquibase 或 Spock 解决这个问题？同样，它在生产中运行良好，我只是无法对其进行集成测试（这可能是 H2 限制？）

更新：我有另一个具有相同行为的测试 - 无法将 UUID 转换为 class 的字符串属性。如果我将“UUID.randomUUID()”更改为“123”，它会按预期工作。

因为我只在我的测试中看到了这一点，而 SqlExceptionHelper 是个例外，我想知道测试 H2 是否不能处理生产 Postgres 所做的转换？我为 HSQL 更改了 H2 并得到了相同类型的错误。

Device.deviceID 的类型是 String，但您的 Spock 规范中 deviceId 的类型是 UUID。所以你要么需要使用

def device = new Device(internalId: internalId, deviceId: deviceId.toString(), ...

或

where:
deviceId                     | ...
UUID.randomUUID().toString() | ...

真的就是这么简单
