1.导入需要的jar包

a)      spring-beans

b)      spring-context

c)      spring-core

d)      spring-expression

e)      spring-web

f)       spring-webmvc

g)      commons-logging(日志包)

2.在web.xml中配置DispatcherServlet服务(通过springMVC-servlet.xml)

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

  <display-name>SpringMVC</display-name>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

 

  <servlet>

      <!-- springMVC默认路径是:/WEB-INF/servletName-servlet.xml

             可以通过init-param来更改:paeam-name:contextConfigLocation,param-value:classpath:(编码后xml所在的具体位置)

      -->

      <servlet-name>springMVC</servlet-name>

      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  </servlet>

  <servlet-mapping>

      <servlet-name>springMVC</servlet-name>

      <url-pattern>*.do</url-pattern>

  </servlet-mapping>

</web-app>

 

3.在springMVC-servlet.xml配置Beans,HandlerMapping(可以不配置默认是:BeanNameUrlHandlerMapping),Controller,InternalResourceViewResolver(加个前缀prefix,后缀suffix)(找文档)

<?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"

    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">

 

       <!-- BeanNameUrlHandlerMapping:通过name找 -->

       <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>

      

    <!-- 配置Controller -->

    <bean name="/my.do" class="com.zhiyou100.kfs.controller.MyController"></bean>

 

       <!-- 配置视图解析器:ViewResolver -->

       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

              <property name="prefix" value="/"/>

              <property name="suffix" value=".jsp"/>

       </bean>

</beans>

 

4.创建Controller,返回ModelAndView对象(还可以是String,java对象(json))

package com.zhiyou100.kfs.controller;

 

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

 

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.AbstractController;

 

public class MyController extends AbstractController{

 

       @Override

       protected ModelAndView handleRequestInternal(HttpServletRequest req, HttpServletResponse resp) throws Exception {

              ModelAndView mv=new ModelAndView();

              mv.setViewName("login");

              mv.addObject("name", "login<br/>hello!");

              return mv;

       }

 

}

 

5.在视图解析层(InternalResourceViewResolver)通过ModelAndView找视图(jsp、excel、pdf、php...)

6.根据视图解析层提供的位置创建jsp

7.web工程包结构:
