spring – 使用tx:annotation-driven可以防止自动装配bean

我正在使用Spring MVC和Virgo Webserver在OSGi应用程序上开发一个模块.

在我的模块上,我有一个Controller,它可以访问Manager,它有一个负责处理报告生成的处理程序列表.

一切都很好,直到我不得不从外部服务调用事务方法.由于我的所有类都不是事务性的,因此我必须添加对转换管理器和注释驱动的引用.然后,我的经理停止接到通知.

我知道当使用注释驱动时,我的所有bean必须实现一个公共接口才能使代理机制起作用.据我所知,所有课程都是(其中一个不是,但后来我改了).

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"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<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>

我的bundle-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"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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"
interface="org.springframework.web.servlet.HandlerMapping"
context-class-loader="service-provider"
auto-export="interfaces"/>

<osgi:service interface="reportmodule.api.manager.ReportManager" ref="reportManager" auto-export="interfaces"/>

<osgi:service interface="reportmodule.api.manager.ReportHandler" ref="mvpepReportHandler" auto-export="interfaces"/>

<osgi:service interface="reportmodule.repository.ReportConfigurationDAO" ref="reportConfigDao" auto-export="interfaces"/>

<osgi:service interface="reportmodule.osgi.OSGIChangeReportHandler" ref="oSGIChangeReportHandler" auto-export="interfaces"/>

<osgi:list cardinality="0..N" id="reportHandler" interface="reportmodule.api.manager.ReportHandler" greedy-proxying="true">
<osgi:listener ref="oSGIChangeReportHandler" bind-method="register" unbind-method="unregister"/>    
</osgi:list>

</beans>

因此,在发布所有服务之后,调用oSGIChangeReportHandler.register(我能够对其进行调整):

@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);
    }


}

虽然调试器在register方法上显示了reportManager和reportHandler的Proxies,但调试器不会在ReportManagerImpl.addReportHandler方法上停止:

@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);
        }
    }

}

我必须强调,当我从bundle-context.xml文件中删除tx:annotation-driven标记时,一切正常(处理程序在启动期间正确添加到列表中).

那么,我在这里错过了什么?

最佳答案
问题解决了!

正如您在上面的代码中看到的那样,我通过XML和Annotation定义了bean,因此每个bean都在运行时被复制.然后,当我添加tx:annotation-driven标签时,应用程序开始拦截错误的bean.它确实是在通知一个豆子,而是一个孤儿豆.
