java AEM 6.5@Reference（target=“（component.name=componentName）”）不工作

Question

我正在尝试使用@Reference注释的target属性注入AEM组件

这就是我试图注入的组件

import org.osgi.service.component.annotations.Component;
import okhttp3.Interceptor;


@Component(immediate = true, name = "myInterceptorComponent", service = {Interceptor.class})
public class myInterceptor implements Interceptor {

  public static final String COMPONENT_NAME = "myInterceptorComponent";
    
  //... some implementation

}

这是使用它的组件，它是：

import okhttp3.Interceptor;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

@Component(immediate = true)
public final class anotherComponent {

  @Reference(target = "(component.name=myInterceptorComponent)")
  private Interceptor myInterceptor;
  
  //... another implementation
}

这是我正在运行的测试：

@ExtendWith({AemContextExtension.class})
class anotherComponent Test {
    private final AemContext context = AppAemContext.newAemContext();

    @BeforeEach
    public void setUp() {
        this.context.registerInjectActivateService(myInterceptor.class);
        this.context.registerInjectActivateService(anotherComponent.class);
    }

    @Test
    void testMethod(){
        //Test implementation
    }
}

运行测试时，出现以下错误： org.apache.sling.testing.mock.osgi.ReferenceViolationException: Unable to inject mandatory reference 'myInterceptor' for class com.test.anotherComponent : no matching services were found.

如果我使用@Reference引用组件，而不使用target属性，那么测试工作正常。不幸的是，我有不止一个拦截器，component.name属性让我区分它们

你知道为什么会失败吗

注册服务时，需要传递其他配置以指定目标名称。 在您的情况下，类似于：

this.context.registerInjectActivateService(new MyInterceptor(), Collections.singletonMap("component.name", "myInterceptorComponent"));
