我正在创建一个简单的 spring mvc 应用程序。如何配置 spring DispatcherServlet 以接受如下所示的 url 模式。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>SpringMVC</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

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

  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

目前我在启动应用程序时收到低于警告。

WARNING: No mapping found for HTTP request with URI [/SpringMVC/] in DispatcherServlet with name 'spring'

spring-servlet.xml（我也添加了默认的 servlet 处理程序）

首先，您的 web.xml 应该包含 DispatcherServlet 映射（您可以提供 dispatcher-servlet.xml 文件位置或使用默认值）：

    <servlet>
            <servlet-name>dispatcher-servlet</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                    <param-name>contextConfigLocation</param-name>
                    <param-value>/WEB-INF/classes/spring-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
            <servlet-name>dispatcher-servlet</servlet-name>
            <url-pattern>/</url-pattern>
    </servlet-mapping>

将此添加到您的 spring-servlet.xml 文件中：

<mvc:annotation-driven/>

主要步骤，您应该创建将映射到您的路径 /SpringMVC 的控制器，例如

package com.springapp.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


@Controller
@RequestMapping("/SpringMVC")
public class MyController{

     @RequestMapping(method= RequestMethod.GET)
     public ModelAndView springMvcTest(ModelMap modelMap){
         return new ModelAndView("test");
     }
}

尝试使用以下方法之一： 

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/SpringMVC/*</url-pattern>
</servlet-mapping>

或者：

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.form</url-pattern>
</servlet-mapping>

在网页 xml 中

 <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>/</url-pattern>
    </servlet-mapping>

在你的控制器中：

@Controller
@RequestMapping("SpringMVC")
public class MyController {
    Logger logger = LoggerFactory.getLogger(MyController.class);
    @Autowired
    private ContentService contentService;

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String createForm(@RequestParam("user") String user, @RequestParam("requestId") String requestId, Model uiModel) {

 //TODO 
        return "index";
    }

然后您的网址将是 ... localhost:port/SpringMVC/index

您必须在控制器中映射此 url，如下所示：

 @RequestMapping("/SpringMVC")
   public ModelAndView index(HttpServletRequest req,HttpServletResponse){

     // ur business logic

   return new ModelAndView("index");  
  }
