public class PosterTag extends TagSupport { private int posterParentCode; // 广告分类cd private int posterSonCOde; // 广告内容cd public int getPosterParentCode() {

} public void setPosterParentCode(int posterParentCode) {

} @Override
public int doStartTag() throws JspException {
// 初始化spring配置文件applicationContext.xml
ApplicationContext appContext = new ClassPathXmlApplicationContext(
"applicationContext_ProvinceAndCity.xml");
// 然后拿到service类：
PosterService posterService = (PosterService) appContext
.getBean("posterService");
HttpServletRequest request = (HttpServletRequest) pageContext
.getRequest(); // 创建页面请求对象
JspWriter out = pageContext.getOut(); // 获取jsp页面输出对象
// 调用类中的方法：
List posterList = posterService.queryPosterParentAndPosterSon(
posterParentCode, posterSonCOde);
for (int i = 0; i < posterList.size(); i++) {
System.out.println(posterList.get(i));//测试用看看后台能不能输出数据
}
try {
out.append(posterSonCOde + ":" + posterParentCode + "栏目下没有文章");
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return super.doStartTag();
}
applicationContext_ProvinceAndCity.xml 中的内容<bean id="posterDao" class="com.cattle.daoImpl.PosterDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<bean id="posterService" class="com.cattle.serice.PosterService">
<property name="posterDao" ref="posterDao"></property>
</bean>

请问大家这个是什么问题？ 为什么会找不到'sessionFactory' 呢？
