java - Spring MVC : URL Pattern

Question

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>

如果我更改此代码

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

到

<url-pattern>/learn/abc/</url-pattern>

我可以点击我的 Controller 代码，如下所示

@Controller
@RequestMapping(value = "/learn")
public class ControllerClass
{
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String callRequest(ModelMap model)
    {
        return "index";
    }

    @RequestMapping(value = "/abc/", method = RequestMethod.GET)
    public String personController(ModelMap model)
    {
        return "welcome";
    }
}

但我也想使用第一种方法，否则我将添加更多方法，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

使用此 url 模式 <url-pattern>/learn/*</url-pattern>配置，要命中您的方法，url 路径将为:/learn/learn

web.xml 上的 url-pattern 属性就像 spring servlet 的基本路径。因此，一个不错的选择是将 url-pattern 更改为/* ，如下所示:

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

或者，如果您想要一些基本路径，请将 url 模式更改为如下所示:/基本路径/*

要使用您的方法，您需要使用路径 url:/basepath/learn
