java - Spring 4.07 Junit 测试和 Autowiring

Question

嗨，我正在使用 Spring 和 CDI。在我的单元测试中，我想测试一个使用 @Autowired 注释的类。问题是，如果我创建此类的实例并调用方法，则所有带注释的对象均为空。基本上注释是有效的。只是在我的单元测试中它没有

这是我的单元测试。 Autowired 在这里起作用。在我的测试中，我创建了 DemoConsumerBean.class 的实例，并调用方法 requestJobsFromPublishedJobsApi ，这里我还有一些 Autowired 声明。问题是所有实例都是空的!

@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(); 中使用 new 绕过 spring，这是你的问题。

要么使用 spring 中的 DemoConsumerBean 实例(即在测试中 Autowiring )，要么添加 setter 并使用它们在测试中的 DemoConsumerBean 中“手动 Autowiring ”:

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