关于ssm整合的豆知识<一>

在整合过程中如果遇到：

org.springframework.beans.factory.NoSuchBeanDefinitionException:

No matching bean of type [com.Dao.UserDao] found for dependency:

expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations:

{@org.springframework.beans.factory.annotation.Autowired(required=true)}

那么可以优先查看你的web.xml监听器是否被启动

我的监听器代码

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

添加上后问题解决
