我正在使用Spring MVC和Virgo Webserver在OSGi應用程序上開發模塊。使用tx：annotation-driven防止自動裝配bean
在我的模塊上，我有一個Controller，它訪問一個Manager，它有一個負責處理報告生成的處理程序列表。
一切都很好，直到我不得不從外部服務調用交易方法。由於我的班級都不是交易型的，所以我必須添加對Transation經理和annotation-driven的引用。然後，我的經理停止通知。
據我所知，在使用annotation-driven時，我的所有bean必須實現一個公共接口，以便代理機制能夠工作。據我所知，所有的類都是（其中一個不是，但是我改變了它）。
我的配置文件是：
束-context.xml中：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

<context:annotation-config />
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="reportManager" class="reportmodule.manager.impl.ReportManagerImpl"/>
<bean id="mvpepReportHandler" class="reportmodule.manager.impl.MVPEPReportHandler"/>
<bean id="reportConfigDao" class="reportmodule.repository.impl.ReportConfigurationHibernateDAOImpl"/>
<bean id="oSGIChangeReportHandler" class="reportmodule.osgi.impl.OSGIChangeReportHandlerImpl"/>
<bean id="reportController"
class="reportmodule.controller.impl.ReportControllerImpl"/>
<bean id="reportControllerHandlerMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<value>/module/reportController/**=reportController</value>
</property>
<property name="alwaysUseFullPath" value="true"></property>
</bean>
</beans>
和我的包，osgi.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:osgi="http://www.springframework.org/schema/osgi"
xmlns:osgi-compendium="http://www.springframework.org/schema/osgi-compendium"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/osgi
http://www.springframework.org/schema/osgi/spring-osgi.xsd
http://www.springframework.org/schema/osgi-compendium
http://www.springframework.org/schema/osgi-compendium/spring-osgi-compendium-1.2.xsd">
<osgi:reference id="transactionManager" interface="org.springframework.transaction.PlatformTransactionManager" />
<osgi:reference id="sessionFactory" interface="org.hibernate.SessionFactory" />
<osgi:reference id="smaCoreUtilService" interface="core.util.service.SmaCoreUtilService" />
<osgi:service ref="reportControllerHandlerMapping"

<osgi:listener ref="oSGIChangeReportHandler" bind-method="register" unbind-method="unregister"/>
</osgi:list>
</beans>
所以，畢竟該服務正在發佈oSGIChangeReportHandler.register被稱爲（我可以debbug它）：
@Service(value="oSGIChangeReportHandler")
public class OSGIChangeReportHandlerImpl implements OSGIChangeReportHandler {
private ReportManager reportManager;
/**
* @param reportManager the reportManager to set
*/
@Autowired
public void setReportManager(ReportManager reportManager) {
this.reportManager = reportManager;
}
@SuppressWarnings("rawtypes")
public void register(ReportHandler reportHandler, Map properties) {
reportManager.addReportHandler(reportHandler);
}
@SuppressWarnings("rawtypes")
public void unregister(ReportHandler reportHandler, Map properties) {
reportManager.removeReportHandler(reportHandler);
}
}
雖然調試器顯示了register方法爲reportManager和reportHandler兩個代理服務器，調試器不會在ReportManagerImpl.addReportHandler方法停止：
@Service(value="reportManager")
@Transactional(propagation = Propagation.MANDATORY, rollbackFor = Exception.class)
public class ReportManagerImpl implements ReportManager {
private ReportConfigurationDAO reportConfigurationDAO;
private ArrayList<ReportHandler> reportHandlers = new ArrayList<ReportHandler>();
/**
* @param reportConfigurationDAO the reportConfigurationDAO to set
*/
@Autowired
public void setReportConfigurationDAO(ReportConfigurationDAO reportConfigurationDAO) {
this.reportConfigurationDAO = reportConfigurationDAO;
}
@Override
@Transactional
public InputStream gerarRelatorio(ReportRequest repoReq) throws NegocioException {
// Generates the report...
}
/* (non-Javadoc)
* @see reportmodule.api.manager.ReportManager#addReportHandler(reportmodule.api.manager.ReportHandler)
*/
@Override
public void addReportHandler(ReportHandler handler) {
if (handler != null) {
this.reportHandlers.add(handler);
}
}
/* (non-Javadoc)
* @see reportmodule.api.manager.ReportManager#removeReportHandler(reportmodule.api.manager.ReportHandler)
*/
@Override
public void removeReportHandler(ReportHandler handler) {
if (handler != null) {
this.reportHandlers.remove(handler);
}
}
}
我必須強調的是，當我刪除tx:annotation-driven標籤從bundle-context.xml文件，一切工作正常（handler已正確添加到列表在啓動過程中）。
那麼，我在這裏錯過了什麼？
是'reportManager' 'oSGIChangeReportHandler.register'中的null？ – Avi
不！它在調試器上顯示一個代理對象。但我已經解決了這個問題，答案如下。感謝評論，tho。 :) –
