操作方法
大家看看applicationContext.xml中的配置如下： <bean id="FacebookVoteRecordDAO" class="hk.egame.web.dao.FacebookVoteRecordDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteSubjectDAO" class="hk.egame.web.dao.FacebookVoteSubjectDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteTitleDAO" class="hk.egame.web.dao.FacebookVoteTitleDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteMgr" class="hk.egame.facebook.service.FacebookVoteMgr"> <property name="facebookVoteRecordDAO"><ref local="FacebookVoteRecordDAO" /></property> <property name="facebookVoteSubjectDao"><ref local="FacebookVoteSubjectDAO" /></property> <property name="facebookVoteTitleDAO"><ref local="FacebookVoteTitleDAO" /></property> </bean> <bean name="/facebook/vote" class="hk.egame.facebook.action.FacebookVoteAction"> <property name="facebookVoteMgr"><ref bean="FacebookVoteMgr" /></property> </bean> 而FacebookVoteMgr.java中： private FacebookVoteRecordDAO facebookVoteRecordDAO; private FacebookVoteSubjectDAO facebookVoteSubjectDao; private FacebookVoteTitleDAO facebookVoteTitleDao; public void setFacebookVoteRecordDAO(FacebookVoteRecordDAO facebookVoteRecordDAO) { this.facebookVoteRecordDAO = facebookVoteRecordDAO; } public void setFacebookVoteSubjectDao(FacebookVoteSubjectDAO facebookVoteSubjectDao) { this.facebookVoteSubjectDao = facebookVoteSubjectDao; } public void setFacebookVoteTitleDao(FacebookVoteTitleDAO facebookVoteTitleDao) { this.facebookVoteTitleDao = facebookVoteTitleDao; } applicationContext.xml中的正确配置： <bean id="FacebookVoteRecordDAO" class="hk.egame.web.dao.FacebookVoteRecordDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteSubjectDAO" class="hk.egame.web.dao.FacebookVoteSubjectDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteTitleDAO" class="hk.egame.web.dao.FacebookVoteTitleDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property> </bean> <bean id="FacebookVoteMgr" class="hk.egame.facebook.service.FacebookVoteMgr"> <property name="facebookVoteRecordDAO"><ref local="FacebookVoteRecordDAO" /></property> <property name="facebookVoteSubjectDao"><ref local="FacebookVoteSubjectDAO" /></property> <property name="facebookVoteTitleDao"><ref local="FacebookVoteTitleDAO" /></property> </bean> <bean name="/facebook/vote" class="hk.egame.facebook.action.FacebookVoteAction"> <property name="facebookVoteMgr"><ref bean="FacebookVoteMgr" /></property> </bean> 结论如下： applicationContext.xml中bean的property的name必须和set方法注入时的名字完全相同，包括大小写。 报错内容如下： [08:51:42.546] {main} org.springframework.beans.factory.BeanCreationException:Error creating bean with name 'FacebookVoteMgr'
