核心思想：

这里写图片描述

步骤：

这里写图片描述
1. 客户端向spring容器发起一个http请求
2. 发起的请求被前端控制起所拦截(DispatcherServlet)，前端控制器会去找恰当的映射处理器来处理这次请求
3.
4. 在控制器中处理所发送的请求，并以modeandView（属性值和返回的页面）的形式返回给向前端控制器
5. 前端控制器通过查询viewResolver对象来试着解决从控制返回的视图
6. 如果前端控制找到对应的视图，则将视图返回给客户端，否则抛异常。

入门配置：

pom.xml(将maven仓库地址改成国内的):

contextConfigLocation下的value表示配置文件在/WEB-INF/applicationContext.xml；

servlet-mapping下的url-pattern表示以这个结尾的请求会通过这个servlet。（还可以试.jsp,.html等）

applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"        xmlns:aop="http://www.springframework.org/schema/aop"        xmlns:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc"        xmlns:tx="http://www.springframework.org/schema/tx"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">    <mvc:annotation-driven />    <context:component-scan base-package="com.fly.*" />    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/" />        <property name="suffix" value=".jsp" />    </bean></beans>

表示当spring在启动时，回加载这个包下面的所有组件（这就包的自动扫描机制，即spring会将标有@Controller @Component等类加载到spring容器管理中）

ViewResolver是一个使徒解析器，就是我们第一部分提到的springMVC生命周期中的第五步，上面这段的配置的意思就是，当我们从后端控制器中返回的视图时，前端控制器就根据这一段配置来返回一个具体的视图，如后端控制返回的是一个hello，根据上面的配置，最后前端控制器会组并成这样的一个地址：hello.jsp(/代表根目录下),然后从根目录下面查找一个hello.jsp返回客户端。

Controller:

package com.fly.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.fly.model.Book;@Controller@RequestMapping("/book.do")public class IndexController {    @RequestMapping(params = "method=add")    public String add(Book book){        System.out.println("bookname:" + book.getName());        System.out.println("author:" + book.getAuthor());        return "success";    }}

index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"    pageEncoding="ISO-8859-1"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body>    <form method="post" action="<%=request.getContextPath()%>/book.do?method=add">        bookname:<input type="text" name="name" id="name">         author:<input type="text" name="author" id="author">         <input type="submit" value="Add">    </form></body></html>

Book:

package com.fly.model;public class Book {    private int id;    private String author;    private String name;    public Book(){}    public Book(int id, String author, String name){        super();        this.id = id;        this.author = author;        this.name = name;    }    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getAuthor() {        return author;    }    public void setAuthor(String author) {        this.author = author;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}
