Spring MVC：URL模式

Question

這是我的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>

如果我更改此代碼

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

至

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

我可以點擊我的控制器代碼

@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";
    }
}

但我也想打第一種方法，否則我將添加更多方法，這是我無法實現的

/learn/abc/

在網址映射中。

所以請幫我

pom.xml

請讓我知道我是否錯過任何依賴

Answer 1

使用此url-pattern <url-pattern>/learn/*</url-pattern>配置，要執行您的方法，URL路徑將為： / learn / learn

web.xml上的url-pattern屬性就像spring的servlet的基本路徑一樣。 因此，一個不錯的選擇是將url-pattern更改為/ *，如下所示：

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

或者，如果您需要一些基本路徑，請將url模式更改為如下形式：/ basepath / *

要使用您的方法，您需要使用路徑URL： / basepath / learn
