Java springmvc:URL模式

这是我的web.xml

<servlet>
      <servlet-name>Learn</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <servlet-mapping>
      <servlet-name>Learn</servlet-name>
      <url-pattern>/learn/*</url-pattern>
   </servlet-mapping>

但我也想点击第一个方法，否则我会添加更多的方法，这是我无法实现的

/learn/abc/

在url映射中

所以请帮我解决这个问题

如果我错过了此url模式的任何依赖项，请告诉我，要点击您的方法，url路径将是：/learn/learn

web.xml上的url模式atribute的工作原理类似于spring的servlet的基本路径。因此，一个好的选择是将url模式更改为/*，如下所示：

<url-pattern>/*</url-pattern>

/*

或者，如果您需要一些基本路径，请将url模式更改为以下内容： /基本路径/*

---

要使用您的方法，您需要使用路径url:/basepath/learn

，那么如果您不更改

，即将其保留为

/learn/*

，会发生什么？对

/learn/

和

/learn/abc/

的请求都有效吗？它对任何人都有效，但我想要url，因此如果它包含/learn/在其中，那么它会击中控制器，问题是，当您将url更改为

/learn/*

时，它没有命中

callRequest

方法，对吗？在这种情况下，它没有命中任何方法，但从逻辑上讲它应该。。正当

/learn/abc/
