本文详细介绍如何从零开始搭建Spring MVC项目，包括创建Web项目、配置lib库、编辑web.xml、设置DispatcherServlet、定义Controller及视图解析等步骤。

一、首先建立一个Web项目

二、把lib包导入到WEB-INF的lib目录下

这里写图片描述

三、修改WEB-INF下的web.xml

添加

<servlet>
    <servlet-name>springmvc</servlet-name>
    //此处的名字与新建的xml文件有关
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>

四、新建一个xml文件，名字为xxx-servlet.xml，其中xxx为servlet-name

五、修改xxx-servlet.xml

<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- springmvc 注解驱动 -->
    <mvc:annotation-driven/>

    <!-- 扫描com包下的controller -->
    <context:component-scan base-package="com"/>

    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 跳转路径 -->
        <property name="prefix" value="/view/"></property>
        <!-- 页面后缀 -->
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

六、新建一个Controller

package com.sam.controller;

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

@Controller
@RequestMapping("/user")
public class UserController {

    @RequestMapping(value="/list")
    public String list(){

        System.out.println("----查询用户信息----");

        return "userinfo/user_list";
    }
}

七、JSP页面

路径

这里写图片描述

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<!DOCTYPE HTML>
<html>
  <head>
    <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>

  <body>

  <a href="user/list.do">查询</a>

  </body>
</html>

user_list.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE html>
<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP 'user_list.jsp' starting page</title>

    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->

  </head>

  <body>
    <h1>查询用户信息</h1>
  </body>
</html>
