SpringMVC入门案例
最近在了解Spring MVC框架，试做一个入门程序了解其基本使用。
1、新建Java Web项目，导入相应jar包：
2、右击项目，new-Source Holder，用于存放配置文件。并新建xml文件“springmvc.xml”置于其中。
3、右击src，新建包。在WEB-INF中新建文件夹“jsp”，并新建jsp文件“itemsList.jsp”置于其中。完成后，项目结构基本完成。
4、配置web.xml：
springMvc01
springmvc
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:springmvc.xml
springmvc
*.action
index.html
index.htm
index.jsp
default.html
default.htm
default.jsp
5、配置springmvc.xml：
6、编写java类：
package com.js.springmvc.first;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
/**
* 入门程序，商品列表查询
* @author js
*
*/
public class ItemController1 implements Controller {
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
// 使用静态数据将商品信息列表显示在jsp页面
// 商品列表
List itemsList = new ArrayList();
Items items_1 = new Items();
items_1.setName("联想笔记本");
items_1.setPrice(6000f);
items_1.setCreatetime(new Date());
items_1.setDetail("ThinkPad T430 联想笔记本电脑！");
Items items_2 = new Items();
items_2.setName("苹果手机");
items_2.setPrice(5000f);
items_2.setDetail("iphone6苹果手机！");
itemsList.add(items_1);
itemsList.add(items_2);
ModelAndView modelAndView = new ModelAndView();
//将数据填充到request
// request.setAttribute("itemsList", itemsList);
modelAndView.addObject("itemsList", itemsList);
//指定转发的jsp页面
modelAndView.setViewName("/WEB-INF/jsp/itemsList.jsp");
return modelAndView;
}
}
package com.js.springmvc.first;
import java.util.Date;
public class Items {
private Integer id;
private String name;
private Float price;
private String pic;
private Date createtime;
private String detail;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name == null ? null : name.trim();
}
public Float getPrice() {
return price;
}
public void setPrice(Float price) {
this.price = price;
}
public String getPic() {
return pic;
}
public void setPic(String pic) {
this.pic = pic == null ? null : pic.trim();
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail == null ? null : detail.trim();
}
}package com.js.springmvc.first;
public class Orderdetail {
private Integer id;
private Integer ordersId;
private Integer itemsId;
private Integer itemsNum;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getOrdersId() {
return ordersId;
}
public void setOrdersId(Integer ordersId) {
this.ordersId = ordersId;
}
public Integer getItemsId() {
return itemsId;
}
public void setItemsId(Integer itemsId) {
this.itemsId = itemsId;
}
public Integer getItemsNum() {
return itemsNum;
}
public void setItemsNum(Integer itemsNum) {
this.itemsNum = itemsNum;
}
}package com.js.springmvc.first;
import java.util.Date;
public class Orders {
private Integer id;
private Integer userId;
private String number;
private Date createtime;
private String note;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number == null ? null : number.trim();
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note == null ? null : note.trim();
}
}package com.js.springmvc.first;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
/**
*
* Title: User
* Description: /p>
*

* @author
* @date 2015-3-1710:00:07
* @version 1.0
*/
public class User implements Serializable {
private int id;
private String username;
private String sex;
private Date birthday;
private String address;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
@Override
public String toString() {
return "User [id=" + id + ", username=" + username + ", sex=" + sex
+ ", birthday=" + birthday + ", address=" + address + "]";
}
}
7、编写itemsList.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
查询商品列表
项目编写完成，访问：http://js-pc:8080/springmvcProj01/itemList.action，页面如下所示。
