Java BundleContext在使用pax考试的单元测试中为空

我正在使用pax考试加载、激活和访问osgi捆绑包

下面的源代码是我的pax考试测试，它使用pax考试2.3和本机容器运行

package fr.xlim.ssd.vtg.osgi;

@RunWith(JUnit4TestRunner.class)
@ExamReactorStrategy(AllConfinedStagedReactorFactory.class)
public class BasicOSGILoaderTest {

    private Logger logger = LoggerFactory.getLogger(BasicOSGILoaderTest.class);

    @Inject
    private BundleContext bundleContext;

    @Configuration
    public Option[] config() {

    String projectRoot = null;

    try {
       projectRoot = ClassLoader.getSystemResource(".").toURI().toURL().toString();
       projectRoot = projectRoot.toString().substring(0,projectRoot.toString().length() - 27);
       logger.debug("project root: {}", projectRoot);
    } catch (MalformedURLException e) {
       logger.error("malformed URL to project root: {}", projectRoot, e);
       throw new IllegalStateException(e);
    } catch (URISyntaxException e) {
       logger.error("URI Syntax Error to project root: {}", projectRoot, e);
       throw new IllegalStateException(e);
    }

    return options(
       junitBundles(),
       logProfile(),
       bundle(projectRoot + "libs/org.eclipse.ant.core_3.2.300.v20110511.jar"),
       bundle(projectRoot + "libs/org.eclipse.core.contenttype_3.4.100.v20110423-0524.jar"),
       bundle(projectRoot + "libs/org.eclipse.core.expressions_3.4.300.v20110228.jar"),
       bundle(projectRoot + "libs/org.eclipse.core.jobs_3.5.100.v20110404.jar"),
       bundle(projectRoot + "libs/org.eclipse.core.resources_3.7.100.v20110510-0712.jar"),
       bundle(projectRoot + "libs/org.eclipse.core.runtime_3.7.0.v20110110.jar"),
       bundle(projectRoot + "libs/org.eclipse.equinox.app_1.3.100.v20110321.jar"),
       bundle(projectRoot + "libs/org.eclipse.equinox.common_3.6.0.v20110523.jar"),
       bundle(projectRoot + "libs/org.eclipse.equinox.preferences_3.4.1.R37x_v20110725.jar"),
       bundle(projectRoot + "libs/org.eclipse.equinox.registry_3.5.101.R37x_v20110810-1611.jar"),
       bundle(projectRoot + "libs/org.eventb.core_2.4.0.r14093.jar"),
       bundle(projectRoot + "libs/org.eventb.core.ast_2.4.0.r14093.jar"),
       bundle(projectRoot + "libs/org.eventb.core.seqprover_2.4.0.r14093.jar"),
       bundle(projectRoot + "libs/org.rodinp.core_1.5.0.r14093.jar"),
       equinox().version("3.7.1")
     );
    }

    @Test
    public void checkBundleContext1() {
       assertNotNull(bundleContext);
    }

    @Test
    public void checkBundleContext2(BundleContext bc) {
       assertNotNull(bc);
    }

    @Test
    public void checkAccessToRodinDB() {
      RodinCore.getRodinDB();
    }
}

但我有以下问题：

• checkBundleContext方法失败、bundle上下文注入（使用

  @Inject

  ）或作为测试方法的参数传递始终为空

• 从bundle

  org.rodinp.core\u 1.5.0.r14093.jar中的class
  RodinCore
  访问静态方法
  getRodinDb（）
  ，即使包
  org.rodinp.core
  在bundle的导出包中，也会抛出一个
  ClassNotFoundException
  关于
  org.rodinp.core.RodinCore
  

检查您的导入。使用

import javax.inject.Inject;

发件人：

注入由javax.inject.inject注释表示。圣像牌 考试自己的1.x发行版行的Inject注释现在是 不赞成

检查相关性：

<groupId>org.ops4j.pax.exam</groupId>
<artifactId>pax-exam-inject</artifactId>

org.ops4j.pax.exam
已添加，但仍不起作用：assertNotNull使用bundleContext注释和
@Inject
抛出AssertionError您是否也可以提供POM？注入由javax.inject.inject注释指示。耶！你说得对：正确的解决方案是使用
javax.inject.inject
。
