   <mvc:annotation-driven /> <context:component-scan base-package="com.hainan.cs.controller"/> <mvc:resources mapping="/resources/**" location="/resources/" />

2. application-config.xml 配置数据源等

    <!-- 配置session factory -->
    <!-- Hibernate 4 SessionFactory Bean definition -->
    <bean id="hibernate4SessionFactory"
