我正在使用 pax-exam 来加载、激活和访问 osgi 包。

以下源代码是我的 pax-exam 测试，它使用本机容器使用 pax-exam 2.3 运行。

package fr.xlim.ssd.vtg.osgi;

import java.net.URISyntaxException;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.ops4j.pax.exam.Inject;
import org.ops4j.pax.exam.Option;
import org.ops4j.pax.exam.junit.Configuration;
import org.ops4j.pax.exam.junit.ExamReactorStrategy;
import org.ops4j.pax.exam.junit.JUnit4TestRunner;
import org.ops4j.pax.exam.spi.reactors.AllConfinedStagedReactorFactory;
import org.osgi.framework.BundleContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import static org.junit.Assert.assertNotNull;
import static org.ops4j.pax.exam.CoreOptions.bundle;
import static org.ops4j.pax.exam.CoreOptions.junitBundles;
import static org.ops4j.pax.exam.CoreOptions.options;

@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 方法都失败了，捆绑上下文注入（使用@Inject）或作为测试方法的参数传递始终为 null

  • 即使包在包的 Export-package 中，从包中的类getRodinDb()访问静态方法也会抛出about 。RodinCoreorg.rodinp.core_1.5.0.r14093.jarClassNotFoundExceptionorg.rodinp.core.RodinCoreorg.rodinp.core

检查您的导入。利用

import javax.inject.Inject;

从服务注入页面：

注入由 javax.inject.Inject 注释指示。Pax Exam 自己的 1.x 版本行的 Inject 注释现已弃用。

检查依赖：

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

它应该包含在 pax-exam 测试中。
