在测试类

Question

我有一个Spring启动应用程序，其测试类如下：

@ContextConfiguration(value = {"classpath:integration/flex-allowcation-assignment-test.xml"})
public class FlexAllowanceAssignmentServiceIntegrationTest extends AbstractSecurityAwareIntegrationTest {

    @Autowired
    private FlexAllowanceAssignmentTestUtils assignmentEndpoint;

    @Test
    public void shouldReturnFailureResponse() {
        // Given
        String message = randomString();
        UserStub user = userBuilder().build();

        // When
        FlexAllowanceServiceResponse response = assignmentEndpoint.assign(message, user);

        // Then
        assertThat(response).isEqualTo(FAILURE);
    }
}

， FlexAllowanceAssignmentTestUtils 类是：

public class FlexAllowanceAssignmentTestUtils {

    private final FlexAllowanceAssignmentGateway flexAllowanceAssignmentGateway;
    private final JacksonWrapper jacksonWrapper;

    @Autowired
    public FlexAllowanceAssignmentTestUtils(FlexAllowanceAssignmentGateway flexAllowanceAssignmentGateway, JacksonWrapper jacksonWrapper) {
        this.flexAllowanceAssignmentGateway = flexAllowanceAssignmentGateway;
        this.jacksonWrapper = jacksonWrapper;
    }

    public FlexAllowanceServiceResponse assign(String message, UserStub user) {
        Message<String> requestMessage = MessageBuilder
                .withPayload(message)
                .build();
        Message<?> response = flexAllowanceAssignmentGateway.assign(enhanceWithSecurityContext(requestMessage, user));
        String payload = (String) response.getPayload();
        return jacksonWrapper.fromJson(payload, FlexAllowanceServiceResponse.class);
    }
}

和 flex-allowcation-assignment-test.xml 文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            receive-timeout="60000"/>

    <int:channel id="flexAllowanceAssignmentRequestChannel"/>

    <int:gateway id="flexAllowanceAssignmentGateway"
                 service-interface="com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentGateway"
                 default-request-channel="flexAllowanceAssignmentRequestChannel"/>

    <bean class="com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentTestUtils"/>

</beans>

尝试运行 FlexAllowanceAssignmentServiceIntegrationTest 时，出现以下异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentServiceIntegrationTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentTestUtils com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentServiceIntegrationTest.assignmentEndpoint; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.orbitbenefits.benefitsselection.server.employee.flexallowance.FlexAllowanceAssignmentTestUtils] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

为什么它看不到在config类中声明的bean-或者我最好在其他地方声明？或者这可能会失败，因为它没有依赖关系（FlexAllowanceAssignmentGateway和JacksonWrapper）？
