在Groovy/Gradle构建中使用JPA复合键时，Spock测试失败

Question

@Table(
        name="MyEntity",
        uniqueConstraints=@UniqueConstraint(columnNames=["channel", "service"])
)
public class MyEntity {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    Long id
    String channel
    String service

我开发了一套关于实体的保存、搜索和修改的Spock测试，一切都运行得很顺利。具体地说，我有一个Spring Boot应用程序冒烟测试，以确保配置正确加载

@ContextConfiguration
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class ApplicationContextSpec extends Specification {

    @Autowired
    WebApplicationContext context

    def "should boot up without errors"() {
        expect: "(web) application context exists"
        context != null
    }
} 

由于自然密钥是channel和service,所以我尝试定义了一个复合密钥

@Table(name="MyEntity")
@IdClass(MyEntityPk.class)
public class MyEntity {

    @Id
    String channel
    @Id
    String service

以及主键类（节选）

public class MyEntityPk implements Serializable {
    String channel
    String service



@ContextConfiguration
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class ApplicationContextSpec extends Specification {

    @Autowired
    WebApplicationContext context

    def "should boot up without errors"() {
        expect: "(web) application context exists"
        context != null
    }
}

Answer 1

冒烟测试无法工作，因为当从“长ID”字段作为主键移动时，我没有执行所有所需的更改

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
Long id

至

@Id
String channel
@Id
String service

我忘记删除repository类中引用“long id”字段的方法。在按照Leonard Brünings的建议转移到Spring-Spock1.1之后，我得到了一个更详细的错误消息，它为我指明了正确的方向。

Error creating bean with name 'modelEntryRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property id found for type ModelEntryEntity!
