Spock mock在嘲笑spring原型“repository”类时返回null-为什么？

Question

我刚刚发现，当使用spock时，除了“存储库”之外，您可以模拟所有的spring原型（“组件”、“服务”和“控制器”）。原因何在？

示例：

@Controller
class TestController {

private final TestRepository testRepository

TestController(TestRepository testRepository) {
    this.testRepository = testRepository
}

@RequestMapping("/test")
String test(Model model) {
    TestModel testmodel = testRepository.getTestModel()
    ...
}

@Repository
class TestRepository {
    TestModel getTestModel() {...}
}

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)
@AutoConfigureMockMvc(secure = false)
@DirtiesContext
class TestControllerSpec extends Specification {
    @Autowired
    MockMvc mockMvc

    @Autowired
    TestRepository testRepository

    def "test"() {
        testRepository.getTestModel >> new TestModel()
    }

    @TestConfiguration
    static class MockConfig {
        def factory = new DetachedMockFactory()
        @Bean
        @Primary
        TestRepository testRepository() {
            factory.Mock(TestRepository)
        }
    }
}

有关更多细节，请参见Spock问题758，简而言之，@repository实例被spring包装在代理中以处理事务，这打破了模拟交互设置。您可以在testrepository字段上使用Spock1.2（目前仅使用快照）和新的注释@unwrapaopproxy。或者您也可以使用此功能手动打开它。

public static <T> T getTargetObject(Object proxy) throws Exception {
    if (AopUtils.isAopProxy(proxy)) {
        return (T) ((Advised) proxy).getTargetSource().getTarget();
    } else {
        return (T) proxy;
    }
}


def "test"() {
    given:
    TestRepository mock = getTargetObject(testRepository)
    mock.getTestModel() >> new TestModel()

    expect:
    testRepository.getTestModel() != null
}
