Spring 4.07 Junit測試並自動接線

Question

嗨，我正在使用Spring和CDI。 在單元測試中，我想測試使用@Autowired批注的類。 問題是如果我創建此類的實例並調用方法，則所有帶注釋的對象都為null。 注釋基本上是有效的。 只是我的單元測試沒有

這是我的單元測試。 在這里，自動布線的作品。 在我的測試中，我創建了DemoConsumerBean .class的實例，並調用方法requestJobsFromPublishedJobsApi，在這里，我還有一些自動裝配的聲明。 問題是所有實例都為空！

@RunWith(SpringJUnit4ClassRunner.class)
@ActiveProfiles("development")
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, FirstbirdTestExecutionListener.class, FlywayTestExecutionListener.class })
@ContextConfiguration(locations = { "classpath:hibernate-spring.xml" })
@FlywayTest
public class DemoConsumerBeanTest extends AbstractJUnit4SpringContextTests {

@Autowired
private CustomerManager customerManager;

@Autowired
private DemoDetailsManager demoDetailsManager;

@Before
public void setup() {
    CamelContext context = new DefaultCamelContext();
    exchange = new DefaultExchange(context);
}

@Test
public void requestJobsFromPublishedJobsApiTest() throws NoSuchDataException {
    DemoConsumerBean demoConsumerBean = new DemoConsumerBean();

    customer = new Customer();
    customer.setCustomerId(15);

    customer = customerManager.getCustomerById(customer);

    // This one works
    DemoDetails demoDetails = demoDetailsManager.getDemoDetailsByCustomerId(customer);

    demoConsumerBean.requestJobsFromPublishedJobsApi(exchange, customer);

    PublishedJobs apiJobs = exchange.getIn().getBody(PublishedJobs.class);

    assertNotNull(apiJobs);

}

}

public class DemoConsumerBean {

@Autowired
protected CustomerManager customerManager;
@Autowired
protected DemoDetailsManager demoDetailsManager;
@Autowired
protected MessageLogManager messageLogManager;

public void requestJobsFromPublishedJobsApi(Exchange exchange, Customer customer) throws NoSuchDataException {
    //this one is null!
    DemoDetails demoDetails = demoDetailsManager.getDemoDetailsByCustomerId(customer);
    PublishedJobs jobs = null;

    if (demoDetails == null || StringUtils.isBlank(demoDetails.getDemoApiUrl())) {
        throw new NoSuchDataException("No demo data found for customer " + customer.getCustomerFirstbirdId());
    }
....
}   

}

在new DemoConsumerBean();使用new new DemoConsumerBean(); 繞過春天，那是你的問題。

使用spring的DemoConsumerBean實例（即在測試中自動裝配）或添加設置器，並使用它們在測試中的DemoConsumerBean中“手動裝配”：

@Test
public void requestJobsFromPublishedJobsApiTest() throws NoSuchDataException {
    DemoConsumerBean demoConsumerBean = new DemoConsumerBean();
    demoConsumerBean.setCustomerManager(this.customerManager)
    // etc
