[eStore] SpringMVC 无JDBC Demo

1. Spring 项目结构:

2. 基础配置文件：

(1) web.xml

<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
    <display-name>Archetype Created Web Application</display-name>

    <servlet>
        <servlet-name>spring-mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

(2) spring-mvc-servlet.xml (该xml的命名同web.xml的dispatchServlet的servlet-name，当然如果想要不同，可以在web.xml下配置不同的xml配置文件名称，供DispatcherServlet初始化配置使用)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" 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">
    <context:component-scan base-package="com.cisco.eStore" />
    <context:annotation-config />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

3. MVC 文档路径：

Controller在com.xx.estore.controller下，Model在com.xx.estore.model, View在spring-mvc-servlet.xml的配置路径下

(1) Controller:

package com.cisco.eStore.controller;

import com.cisco.eStore.model.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/admin")
public class HelloWorldController {

    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public ModelAndView user(){
        return new ModelAndView("user", "command", new User());
    }

    @RequestMapping(value = "/addUser", method = RequestMethod.POST)
    public String addUser(@ModelAttribute("SpringWeb")User user, ModelMap model){
        model.addAttribute("name", user.getName());
        model.addAttribute("password", user.getPassword());
        model.addAttribute("email", user.getEmail());
        return "result";
    }

}

(2) Model:

package com.cisco.eStore.model;

public class User {
    private String name;
    private String password;
    private String email;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

}

(3) view:

user.jsp

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!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=UTF-8">
    <title>用户注册页</title>
</head>
<body>
<h1>This is Add User Page</h1>
<form:form method="POST" action="/admin/addUser">
    <table>
        <tr>
            <td>Name</td>
            <td><form:input path="name"/></td>
        </tr>
        <tr>
            <td>Password</td>
            <td><form:input path="password"/> </td>
        </tr>
        <tr>
            <td>Email</td>
            <td><form:input path="email"/></td>
        </tr>
        <tr>
            <td colspan="2">
                <input type="submit" value="Submit"/>
            </td>
        </tr>
    </table>
</form:form>

</body>
</html>

result.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!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=UTF-8">
    <title>结果页</title>
    <style>
        label{
            margin-right:20px;
        }

    </style>
</head>
<body>
<h1>This is SpringMVC Result Page/h1>
    <label>name:</label><span>${name}</span><br/>
    <label>password:</label><span>${password}</span><br/>
    <label>email:</label><span>${email}</span><br/>
</body>
</html>

4. Demo功能：

(1) 跳转注册用户页：

上述中Controller.user()方法，会跳转到user.jsp，同时新建user对象到jsp中

(2) 添加用户：

上述Controller.addUser()方法，会将页面传来的name, password, email信息填入modelMap中，供result.jsp使用

(3) 展示添加用户信息：

上述Controller.addUser()后 return "result"会直接跳转到 result.jsp，页面中使用${var}方法获取相应参数
