我在web.xml里面定义多个dispatch-servlet的前缀映射，像下面这样

<!-- Servlets -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/guestbook/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/note/*</url-pattern>
    </servlet-mapping>

在controller里面分别有对应的controller

@Controller
@RequestMapping(value = "/note")
public class Note {
    @RequestMapping(value = "/show", method = RequestMethod.GET)
    public String show(Model model) {
        return "note/show";
    }
...
}

 

@Controller
@RequestMapping(value = "/guestbook")
public class Note {
    @RequestMapping(value = "/show", method = RequestMethod.GET)
    public String show(Model model) {
        return "guestbook/show";
    }
...
}

当有多个前缀映射的时候，springmvc就不认得了?

看起来像前缀映射时springmvc取得的参数是url-pattern里面的*的部分。
