【问题描述】：

您好，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。问题是如果我创建这个类的一个实例并调用一个方法，所有带注释的对象都是空的。在基本的注释工作。只是我的单元测试没有

这是我的单元测试。在这里 Autowired 工作。在我的测试中，我创建了一个 DemoConsumerBean.class 的实例并在这里调用方法 requestJobsFromPublishedJobsApi 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());
    }
....
}

}

【解决方案1】：

在new DemoConsumerBean(); 中使用new 会绕过弹簧，这是您的问题。

要么使用 spring 中的 DemoConsumerBean 实例（即在测试中自动装配），要么在测试中添加设置器并使用它们在 DemoConsumerBean 中“手动自动装配”：

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