为什么在测试类中设置spring.profiles.active在实际测试类的环境属性中不可用? &g

Question

我将能够访问environment . getproperty ("spring.profiles.active")在类中，我试图通过设置@ActiveProfiles测试类，

@RunWith(SpringJUnit4ClassRunner.class)
@WebMvcTest(value = TradeController.class)
@ActiveProfiles("test)
class TradeControllerTest{
@Autowired
private MockMvc mockMvc;


@MockBean
private TradeServiceImpl tradeServiceImpl;

@Mock
private ConfigurableEnvironment enviroment;

@Before
public void setup(){
MockitoAnnotations.initMocks(this);
}

@Test
public void test() throws Exception{
Mockito.doNothing().when(tradeServiceImpl).getAllTrades(any());
RequestBuilder requestBuilder = MockMvcRequestBuilder.get(new 
URI("/getTrades")).accept(MediaType.APPLICATION_JSON);
MvcResult  result = mockMvc.perform(requestBuilder).andReturn(); // calling the 
actual class under test
assertEquals(result.getResponse().getStatus(), 400);
}
}

下面是类，我在其中读取spring.profiles.active。然而，它是null

@RestController
public class TradeController{
@Autowired
private TradeServiceImpl tradeServiceImpl; 

@Autowired
private Environment environment;
@GetMapping("/getTrade")
public ResponseEntity<String> getTrade(@PathVariable final String 
tradeId){
String profile = environment.getProperty("spring.profiles.active");
}
}

Answer 1

您不能使用environment.getProperty("spring.profiles.active")访问活动的概要文件，有特定的Environment#getActiveProfiles方法返回为该环境显式激活的概要文件集。因此，如果您在课堂上自动连接ApplicationContextctx，您可以获得以下活动配置文件集:

Environment env = ctx.getEnvironment();
String[] profiles = env.getActiveProfiles();
