为了进行测试，我想在Apache Camel应用程序的蓝图中获得bean的实例。
在JUnit测试中，如何在daos.xml中获取Bean的实例，因为它们将存在于应用程序的OSGI容器中？
的种类
AuditPageNavDao aDao = Daos.getInstance("auditPageNavDao");
我有一个带有插件的Maven pom.xml：
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-Name>DaoServicesCommon</Bundle-Name>
<Bundle-Activator>com.acme.dao.bundle.Activator</Bundle-Activator>
<Meta-Persistence>META-INF/persistence.xml</Meta-Persistence>
<Import-Package>
javax.persistence,
org.hibernate.proxy,
javassist.util.proxy,
*
</Import-Package>
</instructions>
</configuration>
</plugin>
META-INF / persistence.xml看起来像
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

<property name="hibernate.enable_lazy_load_no_trans" value="true" />
<property name="show_sql" value="true" />
</properties>
</persistence-unit>
</persistence>
和OSGI-INF / blueprint / daos.xml看起来像
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"

最后一个激活器是
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
public class Activator implements BundleActivator
{
@Override
public void start(final BundleContext context) throws Exception
{
}
@Override
public void stop(final BundleContext context) throws Exception
{
}
}
最佳答案
这取决于您如何运行测试。有两种方法：
使用PAX EXAM，它将启动OSGi容器并在其中部署捆绑软件
使用CamelBlueprintTestSupport类作为测试的父类，这将启动一个小的嵌入式容器来运行Camel
您可以使用JUnit或TestNG来运行测试，测试框架无关。
还要注意，PAX EXAM可以运行您选择的确切JBoss Fuse版本。
使用PAX EXAM
PAX EXAM通过在容器内注入“探针束”来运行测试。将该探针包想象为正在运行的测试类的“副本”。因此，在测试课程中，您可以完全访问OSGi内部。
然后从BundleContext您可以要求OSGi提供您注册的服务之一。
这是有关如何获取auditPageNavDao bean的粗略思路：
@RunWith(PaxExam.class)
class YourTest {
@javax.inject.Inject
protected BundleContext bundleContext_;
@Test
testMethod() {
ServiceReference<AuditPageNavDao> daoServiceReference_ = bundleContext_.getServiceReference(AuditPageNavDao.class);
AuditPageNavDao dao = bundleContext_.getService(daoServiceReference_);
// use DAO here
}
}
使用CamelBlueprintTestSupport
您可以轻松地与组件和端点进行交互，例如
MyBatisComponent mbc = context.getComponent("mydb", MyBatisComponent.class);
mbc.getSqlSessionFactory().openSession().getConnection();
// don't know if this will work
Object dao = context.getRegistry().lookupByName("auditPageNavDao");
我不知道如何获得Blueprint bean，可能CamelContext是一个很好的起点。
