@PostConstruct 初始化程序在 Spock setup() 方法之前运行，无法及时模拟服务

Question

我有一个服务 (A)，我正在为其编写 Spock 单元测试。此服务使用 init() 方法，用 @PostConstruct 注释，该方法调用另一个服务 (B) 方法。

我的问题是 init() 方法似乎在 Spock setup() 方法之前被调用，所以我从 NullPointerException 得到一个 NullPointerException >init() 因为我的服务 B 是 null （尚未模拟）。我该如何解决这个问题？

要测试的服务 A：

class MasseJournaliseringService {

    BeskedModtagerService beskedModtagerService
    SagslagerIntegrationService sagslagerIntegrationService
    ExecutorService executorService

    private static String s9identity = ConfigHelper.hentConfig(ConfigNoegler.MASSEUDSENDELSESMODUL_FAGSYSTEM_ENTITETSID) as String
    private Principal udfoertAf
    List<Future<String>> futures = []

    @PostConstruct
    void init() {
        udfoertAf = sagslagerIntegrationService.opretPrincipal(s9identity) // NullPointerException!!
        int corePoolSize = ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_COREPOOLSIZE) as int
        int maxPoolSize = ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_POOLSIZE) as int
        int queueCapacity = ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_QUEUE_CAPACITY) as int
        int keepAliveTime = ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_KEEPALIVETIME) as int
        this.executorService = new ThreadPoolExecutor(corePoolSize, maxPoolSize, keepAliveTime, TimeUnit.SECONDS,
                new LinkedBlockingQueue<Runnable>(queueCapacity),
                new CustomizableThreadFactory(threadNamePrefix: 'mu-journ-'))
    }
}

Spock 单元测试：

package beskedfordeler.core.service.broker

import beskedfordeler.core.configuration.ConfigHelper
import beskedfordeler.core.configuration.ConfigNoegler
import beskedfordeler.core.helpers.MasseudsendelseLogHelper

class MasseJournaliseringServiceSpec extends Specification implements ServiceUnitTest<MasseJournaliseringService> {

    def setup() {
        GroovyMock(ConfigHelper, global: true)
        ConfigHelper.hentConfig(ConfigNoegler.BF_FAGSYSTEM_ENTITETSID) >> "FAGSYSTEM"
        ConfigHelper.hentConfig(ConfigNoegler.MYNDIGHED_ERST) >> "MYNDIGHED"
        ConfigHelper.hentConfig(ConfigNoegler.MASSEUDSENDELSESMODUL_FAGSYSTEM_ENTITETSID) >> "FAGSYSTEM_ID"
        service.sagslagerIntegrationService = Mock(SagslagerIntegrationService) // BeanCreationException caused by NullPointerException
        service.beskedModtagerService = Mock(BeskedModtagerService)
        ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_COREPOOLSIZE) >> 5
        ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_POOLSIZE) >> 5
        ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_QUEUE_CAPACITY) >> 10
        ConfigHelper.hentConfig(ConfigNoegler.MSG_BROKER_MU_JOURNALISER_KEEPALIVETIME) >> 60
    }

    // Test cases...
}
