web.xml里面有关url-pattern配置的问题

Question

<servlet>
<servlet-name>webappServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/conf/webapp-dispatcher.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>webappServlet</servlet-name>
<url-pattern>/web/*</url-pattern>
</servlet-mapping> <servlet>
<servlet-name>wapappServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/conf/wapapp-dispatcher.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>wapappServlet</servlet-name>
<url-pattern>/wap/*</url-pattern>
</servlet-mapping>
以上 如果使用 /wap/index 或者/web/index则能准确匹配，但是使用*号 或者直接使用/web/之类则全部报404错误。在线等 很急 谢谢

这个是webapp-dispatcher.xml代码。。
wapapp-dispatcher.xml和上面是一模一样的 只是base-package 和<property name="prefix" value="/WEB-INF/views/webapp/" />不一样

提示错误是：stdout: |WARN | No mapping found for HTTP request with URI [/mvc/wap/index] in DispatcherServlet with name 'wapappServlet' | 2012-12-17 15:30:43176 | org.springframework.web.servlet.DispatcherServlet.noHandlerFound(DispatcherServlet.java:1080) 

Answer 3

确定配置成/*和/web/* 不能访问么，你访问路劲是什么

2个名字一样的servlet？似乎按照你的说法的话是下面这个servlet有效

Answer 5

楼上说的对，2个servlet名字都是webappServlet。

Answer 6

问题点：
1、2个servlet名称冲突，那么第一个servlet将被第二个servlet覆盖，第一个servlet将失效2、关于<url-pattern>/web/*<url-pattern>尽量避免使用web这样的关键字，以免出现莫名奇妙的错误。
以上两点希望对你有所帮助。

<servlet>
<servlet-name>webappServlet</servlet-name>

</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>webappServlet</servlet-name>
<url-pattern>/web/*</url-pattern>
</servlet-mapping> <servlet>
<servlet-name>wapappServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>wapappServlet</servlet-name>
<url-pattern>/wap/*</url-pattern>
</servlet-mapping>楼主这两个配置的都是一样的，冲突啦
