关于spring+jsf 的bean 的配置问题!请高手指教!谢谢	2006年03月10日 16:04

首先我在Spring 的applicationcontext.xml中创建了testService bean
<bean id="testService" class="jobcn.model.service.impl.gzPerdotServiceImpl">
<property name="gzperdotdao"><ref local="gzperdotdao"/></property>
</bean>我在我的日志文件中找到说明创建testService 成功
log:15:27:22,312 INFO SQLErrorCodesFactory:167 - Database product name found in cache {1321194}. Name is Microsoft SQL Server
15:27:22,312 INFO DefaultListableBeanFactory:158 - Creating shared instance of singleton bean 'gzperdotService'
15:27:22,312 INFO DefaultListableBeanFactory:158 - Creating shared instance of singleton bean 'testService'

在我的jsf bean 中需要使用这个bean testService. 我在jsf中的face-config.xml文件也配置了这个property
<managed-bean>
<managed-bean-name>gzperdotBean</managed-bean-name>
<managed-bean-class>jobcn.view.bean.gzPerdotBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>testService</property-name>
<value>#{testService}</value>
</managed-property>
</managed-bean>
但问题总是说我的testService is null 所以就出现了java.lang.NullPointerException这个异常!
请高人指点
