DefaultServlet-servlet.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context.xsd">

    <mvc:annotation-driven/>
    <context:component-scan base-package="com.piglite.*"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

web.xml 入口文件

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  
  <servlet>
    <servlet-name>DefaultServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>
    <servlet-mapping>
        <servlet-name>DefaultServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

MyController.java 这个文件比较简单

package com.piglite.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(value = "/demo",method = RequestMethod.GET)
public class MyController {
    @RequestMapping("/welcome")
    public String welcome(){
        return "welcome";
    }
}

meaven 的 pom.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>

我在 meaven/conf/settings.xml 中修改了镜像路径

  <mirrors>
      <mirror>
          <id>repo2</id>
          <mirrorOf>central</mirrorOf>
          <name>Human Readable Name for this Mirror.</name>
          <url>http://repo2.maven.org/maven2/</url>
      </mirror>
  </mirrors>

终于配置成功了，一路参考过来，
