关于spring的一个莫名其妙的错误

Question

各位高手：
    小弟刚开始学习spring，照着书编的，除了逻辑上改动一下之外，就没什么改动了，但是他一直说我有下面这个错误。严重: Servlet.service() for servlet jsp threw exception
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

真是不知道为什么会有上面那个问题  麻烦高手帮帮忙了，小弟的信心被这东西打击到谷底了

Answer 1

在jsp页面中，我用到了spring:bind
如下<spring:bind path="command.password">
密&nbsp;&nbsp;码:
<input type="password" name="${status.expression}" value="${status.value}" size="14" maxlength="50" style="font-family:arial;font-size:13px;height:20px"/>
<br>
<span style="color:red font-size:11px"><c:out value="${status.errorMessage}"></c:out></span>
</spring:bind>要是我不用<spring:bind path="command.password">的话，就不会出现上述错误了，只要一用，就会有这个错误

Answer 2

  <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>你的spring配置文件配置到web容器里去了么？好像你注释掉了

Answer 3

我一直没搞清楚，applicationContext.xml的作用是什么呀？有了dispatcherServlet-servlet.xml，为什么还要applicationContext.xml呢？？然后，applicationContext.xml是怎么编写的呀？我不是很清楚这里边应该怎么写呢，麻烦指教一下啦，谢谢

Answer 4

ApplicationContext.xml 几乎配置整个项目的80%的部分 , 首先就是dateSource 和 SessionFactory 吧 以前hibernate的工作托管了

Answer 5

需要配置ContextLoaderListener简单的说，ContextLoaderListener是负责加载spring的bean初始化applicationContext的
而DispatcherServlet是用来加载spring的mvc的，如果不用spring mvc而是用struts等mvc框架，那么DispatcherServlet 的配置可以去掉

Answer 6

在ssh中用于托管hibernate、sruts中配置吧

Answer 7

在web.xml里面  <!-- Spring的ApplicationContext.xml的载入 -->    <listener>       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>  加上这句,,,如果你的applicationContext.xml没有改名的话,他会在/WEB-INF下找你的这个文件/WEB-INF/applicationContext.xml找不到你启动TOMCAT的时候又会警告..郁闷啊...<!-- Spring ApplicationContext配置文件的路径,可使用通配符，多个路径用,号分隔      此参数用于后面的Spring-Context loader -->    <context-param>       <param-name>contextConfigLocation</param-name>       <param-value>classpath*:spring/*.xml</param-value>    </context-param>这段代码相信大家一看就清楚是啥回事,对就是把spring/下的所有XML文件都加到classpath里面去..
