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。

这是我要注入的组件。

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
}

这是我正在测试的运行ning:

@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
    }
}

当我运行测试时，出现此错误： 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，则测试有效。不幸的是，我有不止一个拦截器，component.name 属性让我区分它们。

关于失败原因的任何想法？

注册服务时需要传递额外的配置来指定目标名称。在你的情况下是这样的：

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