spring MVC项目起动报错

spring MVC项目启动报错
错误如下：

严重: StandardWrapper.Throwable

controller文件大概如下：

@Controller
@RequestMapping("/query")
public class TestJsonData {

@Autowired
@Qualifier("commonDAO")
private CommonDAO comdao;
}

commonDAO是我在spring启动时的一个bean

<bean id="commonDAO" class="snt.common.dao.base.CommonDAO">
</bean>

是不是配置顺序除了问题？ spring mvc
[解决办法]
第一：你的service实现类是否已经用了@Service
第二：保证你的启动顺序正确，看样子你的spring配置文件没有在启动的时候加载进来。

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
        classpath*:ctxconf/applicationContext.xml
        </param-value>
</context-param>
