eclipse 和Myeclipse中搭建SSH框架的不同

在myeclipse中搭建SSH框架，需要在spring的配置文件applicationContext.xml中：每个注册的DAO方法中定义sessionFactory
例：

--dao注册--
<bean id="adminsDAO" class="com.zhicunkj.dao.impl.AdminsDAO">
     <property name="sessionFactory" ref="sessionFactory"></property> 
</bean>

否则会异常：
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘adminsDAO’ defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: ‘sessionFactory’ or ‘hibernateTemplate’ is required

而在eclipse中不需要每个DAO方法中都配置。
