Spring Boot 2.1：不从 application-test.yml 加载属性

Question

我试图在执行单元测试期间从 application-test.yml 读取属性，但取而代之的是从 application-dev.yml 读取属性。我没有 application.yml 文件。感谢您的帮助。

AppProperties.java

@Component
@ConfigurationProperties(prefix="app")
public class AppProperties {

    private String test;    

    public String getTest() {
        return this.test;
    }

    public void setTest(String test) {
        this.test = test;
    }
}

application-dev.yml

spring:
  profiles: dev
  application:
    name: testApplication
app:
  test: 1

application-test.yml

spring:
  profiles: test
  application:
    name: testApplication
app:
  test: 2

AppServiceTest.java

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {AppProperties.class}, initializers= ConfigFileApplicationContextInitializer.class)
@EnableConfigurationProperties
@ActiveProfiles("test")
public class AppServiceTest{

@Autowired
AppProperties appProperties;

@Test
public void test(){    
    appProperties.getTest();  
    //This returns "1" instead of the desired "2"
}

在单元测试类上使用@SpringBootTest注解

Spring Boot 提供了一个 @SpringBootTest 注解，当您需要 Spring Boot 功能时，可以将其用作标准 spring-test @ContextConfiguration 注解的替代品。注释通过 SpringApplication 创建测试中使用的 ApplicationContext 来工作。除了 @SpringBootTest 之外，还提供了许多其他注释来测试应用程序的更具体的切片。

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {AppProperties.class}, initializers= 
ConfigFileApplicationContextInitializer.class)
@EnableConfigurationProperties
@SpringBootTest
@ActiveProfiles("test")
public class AppServiceTest{

@Autowired
AppProperties appProperties;

@Test
public void test(){    
appProperties.getTest();  
//This returns "1" instead of the desired "2"
 }
