测试中的@ConfigurationProperties 抛出 NullPointer

我正在为 Spring Batch 编写集成测试 - 我决定编写一个单独的配置作为测试资源 (*.csv)。这是它的样子：

@ConfigurationProperties(prefix = "resources")
@Data
@TestConfiguration
public class ResourcesTestConfig {
    private Resource first;
    private Resource second;
}

//appliication.yml
resources:
  first: classpath:first.csv
  second: classpath:second.csv

@SpringBootTest
@ActiveProfiles("test")
@Slf4j
@EnableConfigurationProperties
public class SpringBatchApplicationIntegrationTest {
    @Autowired
    private ResourcesTestConfig resourcesConfig;

    @Test
    public void someTest() {... }
}

就这样。资源测试配置 = 空。

从我尝试做的事情来看：

替换@TestConfiguration为@Configurationor @Component，并完全删除。我添加到@EnableConfigurationProperties(classes ... my resourcesconfig class)，我还尝试使用注释导入它@Import。用过的@ContextConfiguration(classes... )

不幸的是，它没有用。如何纠正？
