值注释在Junit测试中不起作用

Question

@SpringBootTest
public class RuleControllerTest {

@Value("${myUrl}")
private String myUrl;
private HttpClient httpClient = HttpClients.createDefault();

@Test
public void loadAllRules() throws IOException, URISyntaxException {
    String target = myUrl + "/v2/rules";
    String json = generateHTTPget(target);

    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    Rule[] rules = objectMapper.readValue(json, Rule[].class);

    boolean correctResponse = rules != null ? true : false;
    int httpCode = getHTTPcode(target);
    boolean correctStatus = httpCode >= 200 && httpCode <= 300 ? true : false;

    assertTrue(correctStatus);
    assertTrue(correctResponse);
}

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-test</artifactId>
   <scope>test</scope>
</dependency>

并添加注释

@RunWith(SpringRunner.class)

我得到一条消息：没有测试找到test runner JUnit5，并且在Problems选项卡中有SpringBootTest.jar无法读取或者不是有效的ZIP文件

也试过

@PropertySource("classpath:application.properties")

我也试过：

@RunWith(SpringJUnit4ClassRunner.class)

如果我将字符串myUrl硬编码为“http：//localhost:8090”，则测试工作正常，因此问题在于@value不工作

Answer 1

跟踪对我有用。它从application.properties文件中获取值。

@RunWith(SpringRunner.class)
@ContextConfiguration(initializers = ConfigFileApplicationContextInitializer.class)
public class ValueAnnotationTest {

    @Value("${myUrl}")
    private String myUrl;

    @Test
    public void test1() throws Exception {
    assertThat(myUrl).isEqualTo("http://test.com");
    }
}

来自Spring Boot文档：

单独使用ConfigFileApplicationContextInitializer不能提供对@value（“${…}”）注入的支持。它的唯一工作是确保application.properties文件被加载到Spring的环境中。对于@value支持，您需要另外配置一个PropertySourcesPlaceHolderConfigureer或使用@SpringBootTest，它会自动为您配置一个。
