请教spring+hibernate的web.xml配置问题。

Question

小弟SSH新手
   在配置WEB.XML的时候，加上下面的几段话的意思不是读取spring配置信息吗？ 然后在用的时候却空指针异常了。求指导
         <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param> <listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>          <filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>

Answer 2

我是用的是servlet在applicationContext.xml中这样配servlet对不对？
<bean id="userServlet" class="web.UserServlet">
<property name="userManager" ref="userManager" />
</bean>

Answer 3

配了 
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Answer 4

applicationContext-*.xml 统一是放在src目录下的 没问题吧？

Answer 5

我记得applicationContext-*.xml这个文件是放在web-info下面的，
修改一下试试看

Answer 6

classpath:applicationContext-*.xml这个意思不是相当于
/WEB-INF/classes/applicationContext-*.xml 这个的意思吗？
放过了 没效果

Answer 7

servlet没有被spring管理到http://pipe.iteye.com/blog/160575楼主看看这个

Answer 8

你的servlet不是从spring容器中拿出来的spring无法给你注入的

Answer 9

我检查了一下 老是说我的userManager是NULL的 
但是用beanfactoy来读是可以拿到 
看来是配置文件的问题 卡住了 不知道哪里出错 
在servlet上拿不到userManager.....

Answer 10

呕~~  太感谢x19881216了 servlet使用spring还是要写点东西在servlet里面啊~~ 
现在可以正常使用了
