Answer 2

你的web.xml中没有加载spring的配置文件<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/springapp-servlet.xml</param-value>
</init-param>

Answer 3

错误运行的太快了，最开始是报log4j no appender 错误，然后就是报了这么多的错误，只能抓出来这些，我发现这个例子有错误，就是在web.xml和springapp-servlet.xml中的
　＜servlet-mapping＞
　　＜servlet-name＞springapp＜/servlet-name＞
　　＜url-pattern＞*.htm＜/url-pattern＞
　＜/servlet-mapping＞
改成
　＜servlet-mapping＞
　　＜servlet-name＞springapp＜/servlet-name＞
　　＜url-pattern＞*.jsp＜/url-pattern＞
　＜/servlet-mapping＞
　＜bean id="springappController" class="spring.SpringappController"/＞
　＜bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"＞
　＜property name="mappings"＞
　　＜props＞
　　　＜prop key="/hello.htm"＞springappController＜/prop＞
　　＜/props＞
　＜/property＞
＜/bean＞改成
　＜bean id="springappController" class="spring.SpringappController"/＞
　＜bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"＞
　＜property name="mappings"＞
　　＜props＞
　　　＜prop key="/hello.jsp"＞springappController＜/prop＞
　　＜/props＞
　＜/property＞
＜/bean＞

还是那个错误：2005-09-08 14:57:25,827 ERROR [org.springframework.web.servlet.DispatcherServlet] - <Could not complete request>

Answer 5

＜servlet-mapping＞
　　＜servlet-name＞springapp＜/servlet-name＞
　　＜url-pattern＞*.htm＜/url-pattern＞
　＜/servlet-mapping＞
改成
　＜servlet-mapping＞
　　＜servlet-name＞springapp＜/servlet-name＞
　　＜url-pattern＞*.jsp＜/url-pattern＞
　＜/servlet-mapping＞不要改成*.jsp，<prop key="/hello.jsp">springapp</prop>这个地方也要改因为你的页面也叫hello.jsp，url-pattern也叫hello.jsp，
return new ModelAndView("hello.jsp");这样调用会使你的容器进入死循环

Answer 6

谢谢，问题解决了，这个例子没有错，是我问理解错了！
应该用这个url访问:
http://localhost:8083/springapp/hello.htm
