java - 如果设置@Enableconfigurationproperties，为什么@Contexthierarchy不缓存bean？

Question

我决定编写一个没有“@SpringBootTest”的“组件”测试。如果设置@Enableconfigurationproperties，@Сontexthierarchy 不会缓存bean。

当我一起运行“TestOne”和“TestTwo”时，HelloWorld 组件被初始化两次，“init666”中字符串的两次出现就证明了这一点。可能是什么问题？

测试一

@RunWith(SpringRunner.class)
@EnableConfigurationProperties
@ContextHierarchy({
        @ContextConfiguration(classes = TestConfiguration.class),
        @ContextConfiguration(classes = TestOneConfiguration.class)
})
public class TestOne {

    @Autowired
    HelloWorld helloWorld;

    @Test
    public void test () {

    }

}

TestOne配置

@Configuration
public class TestOneConfiguration {
}

测试二

@RunWith(SpringRunner.class)
@EnableConfigurationProperties
@ContextHierarchy({
        @ContextConfiguration(classes = TestConfiguration.class),
        @ContextConfiguration(classes = TestTwoConfiguration.class)
})
public class TestTwo {

    @Autowired
    HelloWorld helloWorld;

    @Test
    public void test () {

    }
}

TestTwo配置

@Configuration
public class TestTwoConfiguration {
}

测试配置

@Configuration
public class TestConfiguration {

    @Bean
    HelloWorld helloWorld () {
        return new HelloWorld();
    }

HelloWorld

@Component

    public class HelloWorld {
        public HelloWorld() {
            System.out.println("init666");
        }
    }

屏幕截图:double appearance of the string in "init666"

附注@SpringBootTest无法使用

目前我找到了唯一的解决方案:

摆脱@Enableconfigurationproperties

从 application.yml 加载属性

TestOne

@RunWith(SpringRunner.class)
@EnableConfigurationProperties
@ContextHierarchy({
        @ContextConfiguration(classes = TestConfiguration.class,
                       initializers = TestContextInitializer.class),
        @ContextConfiguration(classes = TestOneConfiguration.class)
})

public class TestOne {

    @Autowired
    HelloWorld helloWorld;

    @Test
    public void test () {

    }
}

TestContextInitializer

public class TestContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
    @Override
    public void initialize(ConfigurableApplicationContext applicationContext) {
        try {
            Resource resource = applicationContext.getResource("classpath:application.yml");
            YamlPropertySourceLoader sourceLoader = new YamlPropertySourceLoader();
            PropertySource<?> yamlTestProperties = sourceLoader.load("applicationProperties", resource, null);
            applicationContext.getEnvironment().getPropertySources().addFirst(yamlTestProperties);
            String[] profiles = applicationContext.getEnvironment().getProperty("spring.profiles.active").replaceAll(" ", "").split(",");
            applicationContext.getEnvironment().setActiveProfiles(profiles);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

通过Enviroment雕刻所需字段

@Autowired
private Environment environment; 

public Someclass somemethod() {
    Someclass someclass = new Someclass();
    String someField = environment.getProperty("someField");
    someclass.setSomeField(someField);
    return someclass;
}

如果有更好的东西，我会很高兴看到这些建议。
谢谢!
