Unit testing 模拟OSGi上下文中的服务激活异常

在我的Maven项目中，我创建了一个简单的OSGi服务，它只接受一个引用：

import org.apache.sling.api.resource.ResourceResolverFactory;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

@Component
public class MyFoo {
    @Reference
    private ResourceResolverFactory factory;
}

然后，使用osgi模拟教程，我创建了以下测试类：

import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.testing.mock.osgi.junit.OsgiContext;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
public class MyFooTest {
    @Rule
    public OsgiContext mockContext = new OsgiContext();

    @Test
    public void test() {
        ResourceResolverFactory mockFactory = Mockito.mock(ResourceResolverFactory.class);

        mockContext.registerService(ResourceResolverFactory.class, mockFactory);
        mockContext.registerInjectActivateService(new MyFoo());
    }

}

测试在最后一行崩溃，出现以下异常：

org.apache.sling.testing.mock.osgi.NoScrMetadataException: No OSGi SCR metadata found for class MyFoo

    at org.apache.sling.testing.mock.osgi.OsgiServiceUtil.injectServices(OsgiServiceUtil.java:381)
    at org.apache.sling.testing.mock.osgi.MockOsgi.injectServices(MockOsgi.java:148)
    at org.apache.sling.testing.mock.osgi.context.OsgiContextImpl.registerInjectActivateService(OsgiContextImpl.java:153)
    at org.apache.sling.testing.mock.osgi.context.OsgiContextImpl.registerInjectActivateService(OsgiContextImpl.java:141)
    at MyFooTest.testGetResolver(MyFooTest.java:22)

根据互联网上的建议，我已经联系到并确保我的

pom.xml

具有与

maven bundle plugin

完全相同的配置-但这并没有解决问题

知道我在哪里出错了吗？

我尝试复制您的问题，最初遇到了相同的异常，现在可以正常工作了。问题可能是由于类路径损坏，因为

maven-scr-plugin

和

maven-bundle-plugin

之间存在可传递的依赖关系

确保您已准备好以下各项：

• 使用osgi mock 2.x mock依赖项，它与osgi R6兼容。这是我用过的

      <dependency>
          <groupId>org.apache.sling</groupId>
          <artifactId>org.apache.sling.testing.osgi-mock</artifactId>
          <version>2.3.6</version>
          <scope>test</scope>
      </dependency>
  

• 确保插件构建部分包含生成所需DS元数据所需的配置。你可以参考你链接的felix文档，了解更多信息

      <plugin>
          <groupId>org.apache.felix</groupId>
          <artifactId>maven-bundle-plugin</artifactId>
          <extensions>true</extensions>
          <executions>
              <execution>
                  <id>scr-metadata</id>
                  <goals>
                      <goal>manifest</goal>
                  </goals>
              </execution>
          </executions>
          <configuration>
              <exportScr>true</exportScr>
              <instructions>
                  <Bundle-SymbolicName>com.aem.chula.chula</Bundle-SymbolicName>
  
                  <Sling-Model-Packages>
                    com.aem.models
                  </Sling-Model-Packages>
  
                  <_dsannotations>*</_dsannotations>
                  <_metatypeannotations>*</_metatypeannotations>
              </instructions>
          </configuration>
      </plugin>
  

  
  org.apache.felix
  在我的例子中，我必须添加ds注释依赖项
  
  <dependency>
      <groupId>org.apache.felix</groupId>
      <artifactId>org.apache.felix.scr.ds-annotations</artifactId>
      <version>1.2.10</version>
      <scope>provided</scope>
  </dependency>
  
  
  org.apache.felix
  添加对
  org.apache.sling.testing.osgi mock的依赖似乎已经解决了这个问题。谢谢：）
  <dependency>
      <groupId>org.apache.felix</groupId>
      <artifactId>org.apache.felix.scr.ds-annotations</artifactId>
      <version>1.2.10</version>
      <scope>provided</scope>
  </dependency>
