测试中的 Spring bean

Question

我在 applicationContext.xml 中有一个 Spring bean

    <bean id = "mailUser" class="com.company.application.domain.User">
    <property name="username" value="${mail.username}" />
    <property name="password" value="${mail.password}" />

我想将它的内容 Autowiring 到我的测试类中

@Autowired
private User mailUser;

@Test
public void signIn() throws Exception {
    WebDriver driver = new FirefoxDriver();
    driver.get("https://mailservice.com");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.findElement(By.id("username")).sendKeys(getMailUser().getUsername());
    driver.findElement(By.id("password")).sendKeys(getMailUser().getPassword());
    driver.findElement(By.className("btn")).click();

然而，这会导致 NullPointerException。我明白了

    java.lang.NullPointerException

行指向用户名行。有谁知道如何正确修复它？我是新手。

您需要使用@ImportResource 注释将您的XML 配置导入到类中。

@RunWith( SpringJUnit4ClassRunner.class )
@Configuration
@ContextConfiguration( classes = { TestClass.class }, loader = AnnotationConfigContextLoader.class )
@ImportResource( { "classpath:resources/applicationConfig.xml" } )
public class TestClass {}
