java - Spring Boot 中 ApplicationRunner 的单元测试未获取正确的 bean 定义

Question

如何在单元测试中使用@ConditionalOnProperty注解加载配置？

我有以下@Configuration和@Component

@Configuration
@ConditionalOnProperty(value = {"batch"}, havingValue = "Crawler")
public class CrawlerConfiguration
{   
    @Bean
    @Profile("production")
    public Crawler crawler(@Value("${name}") String name)
    {
        return new Crawler(name, true);
    }

    @Bean
    @Profile("test")
    public Crawler crawlerTest(@Value("${name}") String name)
    {
        return new Crawler(name, false);
    }

}


@Component
public class Crawler implements ApplicationRunner
{
    private String name;
    private boolean withScheduler;

    public Crawler(String name, boolean withScheduler)
    {
        this.name = name;
        this.withScheduler = withScheduler;
    }
    @Override
    public void run(ApplicationArguments args) throws Exception
    {
        // do something
    }
}

单元测试。

@RunWith(SpringRunner.class)
@SpringBootTest(classes={CrawlerConfiguration.class})
public class CrawlerTest 
{
    @Autowired
    private Crawler crawler;

    @Test
    public void run() throws Exception
    {
        crawler.run(new DefaultApplicationArguments(new String[]{}));
    }
}

运行此测试会给我这样的警报。

否定匹配:

爬虫配置: 不匹配: - @ConditionalOnProperty (batch=Crawler) 未找到属性“batch”(OnPropertyCondition)

排除:

None

无条件类:

通过在 @SpringBootTest 添加属性来解决...如下所示。

@SpringBootTest(classes={CrawlerConfiguration.class}, properties = {"batch=Crawler", "name=myName"})
