严重: Exception sending context initialized event to listener instance of class cn.tg.core.web.ApplicationListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'systemConfigMngImpl': Autowiring of methods failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void cn.tg.core.manager.impl.SystemConfigMngImpl.setDao(cn.tg.core.dao.SystemConfigDao); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [cn.tg.core.dao.SystemConfigDao] is defined: Unsatisfied dependency of type [interface cn.tg.core.dao.SystemConfigDao]: expected at least 1 matching bean

Mng接口
Java代码
1.public interface SystemConfigMng extends TGCoreManager{
2.}
public interface SystemConfigMng extends TGCoreManager{
}
Mng实现类
@Service
// systemConfigMngImpl
@Transactional
public class SystemConfigMngImpl extends TGCoreManagerImpl
implements SystemConfigMng {
@Autowired
public void setDao(SystemConfigDao dao) {
super.setDao(dao);
}
public SystemConfigDao getDao() {
return (SystemConfigDao) super.getDao();
}
}
在一个servelt里：
Java代码
1.public final class ApplicationListener implements ServletContextListener {
2. private static final String BEAN_NAME = "systemConfigMngImpl";
3. private static final Logger log = LoggerFactory
4. .getLogger(ApplicationListener.class);
5.
6. public void contextDestroyed(ServletContextEvent event) {
7. }
8.
9. public void contextInitialized(ServletContextEvent event) {
10. WebApplicationContext wac = WebApplicationContextUtils
11. .getRequiredWebApplicationContext(event.getServletContext());
12. systemConfigMng = (SystemConfigMng) wac.getBean(BEAN_NAME, SystemConfigMng.class);
13. log.info("系统启动，读取所有站点信息到缓存。");
14. systemConfigMng.loadAllSystemConfigToCache();
15. }
16.
17. private SystemConfigMng systemConfigMng;
18.}
public final class ApplicationListener implements ServletContextListener {
private static final String BEAN_NAME = "systemConfigMngImpl";
private static final Logger log = LoggerFactory
.getLogger(ApplicationListener.class);
public void contextDestroyed(ServletContextEvent event) {
}
public void contextInitialized(ServletContextEvent event) {
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(event.getServletContext());
systemConfigMng = (SystemConfigMng) wac.getBean(BEAN_NAME, SystemConfigMng.class);
log.info("系统启动，读取所有站点信息到缓存。");
systemConfigMng.loadAllSystemConfigToCache();
}
private SystemConfigMng systemConfigMng;
}
用了systemConfigMngImpl就报上面的错，那位大侠能帮忙解决吗？现在那个热锅上的蚂蚁啊！！只有那么多分了……万分感谢！！！
