我第一次使用Spring Dynamic Modules。我试图通过一个bundle公开一个服务(简单的listofValuesDAO Bean),并试图将它注入另一个bundle来使用bean。 下面是Bundle1的osgi-context.xml中的配置标记,通过该标记公开了服务:
<osgi:service ref="listOfValuesDAO" auto-export="interfaces"/>
我试图通过osgi-context.xml中的下面标记在Bundle2中获取它:
<osgi:reference id="listOfValuesDAO" interface="com.dao.IListOfValuesDAO" />
问题在于,当我尝试使用以下配置将它注入Bundle2中的bean:
<bean id="exportServiceImpl" class="com.service.impl.ExportServiceImpl">
<property name="listOfValuesDAO" ref="listOfValuesDAO"/>
</bean>
系统抛出异常:
Exception in thread "SpringOsgiExtenderThread-85"org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'exportServiceImpl' defined in URL [bundle://325.16:0/META-INF/spring/module-context.xml]:
Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'listOfValuesDAO' of bean class [com.service.impl.ExportServiceImpl]:
Bean property 'listOfValuesDAO' is not writable or has an invalid setter method. Did you mean 'listOfValuesDao'?

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:517)
以下是我的ExportServiceImpl类中的属性:
public class ExportServiceImpl implements IExportService {
IListOfValuesDAO listOfValuesDao;
public void setListOfValuesDao(IListOfValuesDAO listOfValuesDao) {
this.listOfValuesDao = listOfValuesDao;
}
public IListOfValuesDAO getListOfValuesDao() {
return listOfValuesDao;
}
}
有人可以帮我解决这个问题吗?
答案 0 :(得分:2)
似乎是案件不一致的问题:listOfValuesDao
和listOfValuesDAO
是不同的名称。
您使用Service中的第一个版本,以及XML bean定义中的第二个版本。尝试:
<bean id="exportServiceImpl" class="com.service.impl.ExportServiceImpl">
<property name="listOfValuesDao" ref="listOfValuesDao"/>
</bean>
