Grails 4 单元测试：“为类配置的连接 [ALL] 无效...”

Question

我在测试配置了多个数据源的 Grails 4 时遇到问题。

领域类

@GrailsCompileStatic
@EqualsAndHashCode(includes = 'authority')
@ToString(includes = 'authority', includeNames = true, includePackage = false)
class Role implements Serializable {

    String authority

    static constraints = {
        authority nullable: false, blank: false, unique: true
    }

    static mapping = {
        datasource ConnectionSource.ALL
    }
}

测试班

class RoleSpec extends Specification implements DataTest {

    void setupSpec() {
        mockDomain Role
    }

    void "test nothing"() {
        expect:
        true
    }
}

我收到此错误：

Invalid connection [ALL] configured for class [class us.cloudcard.api.Role]

应用程序.yml

environments:
  development:
    dataSource:
      pooled: true
      driverClassName: com.mysql.jdbc.Driver
      (rest of the dev datasource ...)
  test:
    dataSource:
      dbCreate: update
      url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
    dataSources:
      readReplica:
        dbCreate: update
        url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE

我不知道该去哪里，所以我可以使用你能提供的任何帮助。

谢谢！

Answer 1

我明确列出了每个数据源，这解决了问题。

    static mapping = {
        cache true
        datasources([ConnectionSource.DEFAULT, 'readReplica'])
    }

但我不太喜欢这个。我不明白为什么

ConnectionSource.ALL

不起作用，因为 docs 说它应该起作用。

Answer 2

SimpleMapDatastore 中似乎没有对 ConnectionSource.ALL 进行处理。 （理论上它应该回退到默认值）

作为一种解决方法，我们可以用以下方法欺骗系统：

test:
    dataSource:
      dbCreate: update
      url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
    dataSources:
      readReplica:
        dbCreate: update
        url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
      ALL:
        dbCreate: update
        url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
