在 Spring Boot 测试中获取配置 属性 class bean

Question

我有一个 class 定义为自动从我的 sprintboot 应用程序中的 applicaton-*.properties 加载属性：

@Component
@ConfigurationProperties("my-app")
@EnableConfigurationProperties
@Data
public class MyAppProperties {

  private String propertyX;
  private String propertyY;

..

}

现在这是我的测试 class:

@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
public class MessageProcessorApplicationTests {

  @Autowired
  private static RestTemplate restTemplate;

  @Autowired
  public static MyAppProperties myAppProperties;

  @Test
  public void testSomething(){
     doSomeSeetup(myAppProperties.getPropertyX()) //myAppProperties is null!! why?
}

在我的测试中，myAppProperties 始终为空。我如何在我的测试中获得这个实例？

Answer 1

将 @EnableConfigurationProperties(value = MyAppProperties.class) 添加到您的测试中 class:

@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
@EnableConfigurationProperties(value = MyAppProperties.class)
public class MessageProcessorApplicationTests {

  @Autowired
  private RestTemplate restTemplate;

  @Autowired
  public MyAppProperties myAppProperties;

  @Test
  public void testSomething(){
     doSomeSeetup(myAppProperties.getPropertyX()) //myAppProperties is null!! why?
}

Answer 2

用 @RunWith(SpringRunner.class) 注释 MessageProcessorApplicationTests 以自动加载 application.properties 文件

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
public class MessageProcessorApplicationTests {

@Autowired
  private static RestTemplate restTemplate;

  @Autowired
  public static MyAppProperties myAppProperties;

  @Test
  public void testSomething(){
     doSomeSeetup(myAppProperties.getPropertyX());

}
