Java UnsatifiedPendencyException:请求的bean当前正在创建无法解析的循环引用

我有一个源类，它显然破坏了集成测试。代码如下所示

@Configuration
@Import( EmailageConfiguration.class )
public class EmailageServiceConfiguration {

    private static final String EMAILAGE_ACCOUNT_ID_CONFIG_KEY = "emailage.key";
    private static final String EMAILAGE_API_KEY_CONFIG_KEY = "emailage.secret";

    private final EmailageConfigHolder holder;

    public EmailageServiceConfiguration( final EmailageConfigHolder holder ) {
        this.holder = holder;
    }

    @Bean
    public EmailageConfigHolder emailageConfigHolder( Environment env ) {

//        final EmailageConfigHolder holder = new EmailageConfigHolder();

        holder.setApiKey( env.getRequiredProperty( EMAILAGE_API_KEY_CONFIG_KEY ) );
        holder.setAccountId( env.getRequiredProperty( EMAILAGE_ACCOUNT_ID_CONFIG_KEY ) );

        return holder;
    }

}

提供了IT测试

public class EmailageServiceIT {

    private static final String EMAILAGE_RESPONSE_FILE = "emailage-response.json";

    private final static String EMAILAGE_ENDPOINT = "/emailage";

    private EmailageService service;

    @Rule
    public WireMockRule wireMockRule = new WireMockRule( wireMockConfig().dynamicPort() );

    @Before
    @SuppressWarnings( "resource" )
    public void setup() {
        int port = wireMockRule.port();

        System.setProperty( "emailage.uri", "http://localhost:" + port + EMAILAGE_ENDPOINT );
        System.setProperty( "emailage.key", "123" );
        System.setProperty( "emailage.secret", "123" );
        System.setProperty( "emailage.connection_timeout", "10000" );
        System.setProperty( "emailage.read_timeout", "10000" );
        System.setProperty( "kafka.bootstrap_servers", "localhost" );
        System.setProperty( "kafka.topic", "ella-test-topic" );

        ApplicationContext context = new AnnotationConfigApplicationContext( EmailageServiceConfiguration.class );
        service = context.getBean( EmailageService.class );
    }


 // .........................

}

当我运行maven命令时，我得到了错误堆栈

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'emailageServiceConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'emailageServiceConfiguration': Requested bean is currently in creation: Is there an unresolvable circular reference?
    at com.ratepay.ella.service.EmailageServiceIT.setup(EmailageServiceIT.java:64)
Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'emailageServiceConfiguration': Requested bean is currently in creation: Is there an unresolvable circular reference?
    at com.ratepay.ella.service.EmailageServiceIT.setup(EmailageServiceIT.java:64)

因此，IT测试基本上在LOC中中断

ApplicationContext context = new AnnotationConfigApplicationContext( EmailageServiceConfiguration.class );

我还为这个问题添加了

EmailageConfigHolder

类

@Getter
@Setter
public class EmailageConfigHolder {

    private String apiKey;
    private String accountId;

}

我该怎么纠正呢？

也许我错了，但是

EmailageServiceConfiguration

负责创建Bean

EmailageConfigHolder

（这不是@Bean注释所表达的吗）

那么spring应该如何将它传递给应该创建它的对象的构造函数呢？这就是你的循环依赖性最可能的来源

若要修复此问题，请为EmailageServiceConfiguration创建一个独立的生产者。

是否可以根据此问题添加示例代码段？我尝试了几个选项，但迄今为止都没有成功。我对spring不是很熟悉，但您是否可以提供有关EmailageConfigHolder的更多信息（以及生成它所需的内容/例如从何处获取环境？）我可以在正确的方向指出你。我在BuffDeCI中添加了<代码> EMAGAGECOMPLAND 这是一个后续问题，因为在发布这个问题后，代码发生了变化：我会考虑调用构造函数<代码>最终eMaGeAcGeFraveWordHealth=新eMaGeEngRealOfDeloDe（）；code>在你的工厂方法中（毕竟，这是一种工厂方法），并重新考虑单元测试/断言（如接受答案的第二段所述）。我同意@sfiss。如果您只是更改了代码以便可以模拟它，我的建议是将其还原为以前的代码，并验证生成的holder对象是否包含正确的值。
