这个例子中，运行时会像你正常起一个 Spring 应用一样效果，会有 Bean 注入、Autowired 的值会被写入，等等。

注意 @ActiveProfiles("local") 必须在 @SpringBootTest 下面。不然不会加载配置文件。目录结构如下：

tsf-resource
    ├── pom.xml
    └── src
        ├── main
        │   ├── java.com.tencent.tsf.resource
        │   |   ├── controller
        │   |   ├── service
        │   └── resources
        │       └── application.yml
        └── test
            ├── java
            │   └── com.tencent.tsf.resource
            │       └── ApiHelperTest.java
            └── resources
                └── application-local.yml

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TsfApplicationStarter.class)
@ActiveProfiles("local")
public class ApiHelperTest {
    private Logger logger = LoggerFactory.getLogger(ApiHelperTest.class);

    @Autowired
    private ContainerConfigV2 containerConfig;

    @Test
    public void testQueryParams() {
        ApiHelper helper = new ApiHelper(containerConfig.getMaster());
        logger.debug("{}", containerConfig.getMaster());
        logger.debug(helper.getUrl("/simple/test/path", null));
    }
}
