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}" />

我想将它的内容自动连接到我的测试类，比如

@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。我懂了

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 {}

当 Spring 自动装配时，它会寻找用于自动装配的构造函数或“getter”（它还说它是按字段执行的，但我从来没有运气）。解决问题的最简单方法是执行以下操作：

public class P{

    private User mailUser;

    @Autowired
    public void setUser(User mailUser) {
        this.mailUser = mailUser;
    }
