搭建记录：springmvc + maven

新建maven项目

选择 maven-archetype-webapp：

填写项目名称：

修改项目配置：

Java Complier 的版本
Project Facets 的版本

同时注意：

Builder Path 中的JDK版本
pom 中builder的JDK版本

添加依赖：

servlet-api

springmvc依赖

添加依赖：

spring-webmvc

修改web.xml

<web-app>  <display-name>Archetype Created Web Application</display-name>  <servlet>    <servlet-name>spring</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <!-- 自定义 默认是servlet-name-servlet.xml-->      <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-servlet.xml</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>spring</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping></web-app>

关于web.xml配置问题：

Servlet 2.3

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-appPUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"“http://Java.sun.com/dtd/web-app_2_3.dtd"><web-app>…</web-app>

Servlet 2.4

<?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/j2ee"xmlns:web="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd "version="2.4">…</web-app>

Servlet 2.5

<?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_2_5.xsd"id="WebApp_ID" version="2.5">

Servlet 3.0

<?xml version="1.0" encoding="utf-8"?><web-app version="3.0"xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

其中：

Servlet 2.5 版本以后支持多个url映射

<servlet-mapping>  <servlet-name>servletName</servlet-name>  <url-pattern>/index</url-pattern>  <url-pattern>/login</url-pattern></servlet-mapping>

新建和上面servlet名称对应的xml

srping-servlet.xml

内容：

<?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:context="http://www.springframework.org/schema/context"    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"    xsi:schemaLocation="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.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx.xsd          http://www.springframework.org/schema/mvc       http://www.springframework.org/schema/mvc/spring-mvc.xsd">    <!-- 配置扫描的包 -->    <context:component-scan base-package="com.grp.*" />    <!-- 注册HandlerMapper、HandlerAdapter两个映射类 -->    <mvc:annotation-driven />    <!-- 访问静态资源 -->    <mvc:default-servlet-handler />    <!-- 处理器映射器 -->    <bean name="/0101" class="com.grp.testing.springmvc.controller.TestingController1"></bean>    <!-- 处理器映射器 -->    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>    <!-- 处理器适配器 -->    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>    <!-- 视图解析器 -->    <bean        class="org.springframework.web.servlet.view.InternalResourceViewResolver">    </bean></beans>

配置路径问题：可在pom的build标签内进行设置（包括其他路径）

    <resources>        <resource>            <directory>src/main/resources</directory>            <excludes>                <exclude>**/*.properties</exclude>                <exclude>**/*.xml</exclude>             </excludes>            <filtering>false</filtering>        </resource>        <resource>            <directory>src/main/java</directory>            <includes>                <include>**/*.properties</include>                <include>**/*.xml</include>            </includes>            <filtering>false</filtering>        </resource>    </resources>

新建类TestingController1

package com.grp.testing.springmvc.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class TestingController1 implements Controller {    @Override    public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {        // TODO Auto-generated method stub        ModelAndView result = new ModelAndView();        result.addObject("data", "123");        result.setViewName("/page/testing1.jsp");        return result;    }}

修改testing1.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>springmvc</title></head><body>    <h1>This is a springmvc testing1</h1></body></html>

运行结果：
