第一步：首先创建两张表，并给表中添加值

第二步：然后创建一个动态工程（注意：不是Java工程）

第三步：接下来创建一个默认的index.jsp文件，该文件中我们写入form表单来提交值（注意：action属性的路径必须要与Controller类路径相对应）

<%@ 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>会员表——消费记录</title>
</head>
<body>
<!-- 使用表单来提交值 -->
	<form action="member/consume">
		用户ID:<input type="text" name="mid">
		<input type="submit" value="确定提交"/>
	</form>
</body>
</html>

第三步：其次创建一个Controller类

package com.zhiyuan.controller;


import java.util.List;


import javax.servlet.http.HttpServletRequest;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


import com.zhiyuan.mapper.MemberMapper;
import com.zhiyuan.pojo.Consume;


//使用@Controller来注释这是一个Controller类
@Controller
// 使用@RequestMapping处理地址映射的注解，表示类中的方法
@RequestMapping("/member")


public class MemberController {
	// 使用@Autowired来进行自动装配
	@Autowired
	// 实例化接口
	MemberMapper imember;


	// 使用@RequestMapping处理地址映射的注解，表示类中的方法
	@RequestMapping("/consume")
	// 定义一个ModelAndView类型的方法并给他参数类型
	public ModelAndView getConsumeList(HttpServletRequest request) {
		// 使用参数名调用getParameter方法获取页面值，该方法中的值要与index.jsp中的页面name属性值保持一致
		//将获取的值转换为int类型
		int res = Integer.parseInt(request.getParameter("mid"));
		//使用List集合来装对应的实体类，并调用接口中的方法
		List<Consume> list = imember.consume(res);
		//实例化ModelAndView，并给他一个参数跳转到所创建的JSP文件中去
		ModelAndView mv = new ModelAndView("consume_list");
		//对象名调用addObject方法一键对应一值
		mv.addObject("consume", list);
		//返回一个ModelAndView对象
		return mv;
	}


}

第四步：创建一个对应的接口，并在接口中定义一个要使用的方法（注意：接口中只能定义方法）

package com.zhiyuan.mapper;

import java.util.List;

import com.zhiyuan.pojo.Consume;

public interface MemberMapper {
	public List<Consume> consume(int id);
}

第五步：创建两个相对应的实体类文件

package com.zhiyuan.pojo;

public class Member {
	private int id;
	private String name;
	private int phone;
	private int money;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getPhone() {
		return phone;
	}
	public void setPhone(int phone) {
		this.phone = phone;
	}
	public int getMoney() {
		return money;
	}
	public void setMoney(int money) {
		this.money = money;
	}
}

package com.zhiyuan.pojo;

public class Consume {
	private int c_id;
	private String c_name;
	private int money;
	private String goods;
	private String servers;
	private String content;
	private int m_id;
	private Member member;
	public int getC_id() {
		return c_id;
	}
	public void setC_id(int c_id) {
		this.c_id = c_id;
	}
	public String getC_name() {
		return c_name;
	}
	public void setC_name(String c_name) {
		this.c_name = c_name;
	}
	public int getMoney() {
		return money;
	}
	public void setMoney(int money) {
		this.money = money;
	}
	public String getGoods() {
		return goods;
	}
	public void setGoods(String goods) {
		this.goods = goods;
	}
	public String getServers() {
		return servers;
	}
	public void setServers(String servers) {
		this.servers = servers;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	public int getM_id() {
		return m_id;
	}
	public void setM_id(int m_id) {
		this.m_id = m_id;
	}
	public Member getMember() {
		return member;
	}
	public void setMember(Member member) {
		this.member = member;
	}
}

第六步：配置xxx-xxx-servlet.xml配置文件（注意：前缀，value的值必须与你的文件名路径相对应）

<?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:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
		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-3.0.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<context:component-scan base-package="com.zhiyuan.controller"/>
	
	<bean id="viewResolve" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
</beans>

第七步：配置web.xml配置文件

<?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" id="WebApp_ID" version="3.0">
  <display-name>Spring-mvc-mybatis</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>
  <filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
<!-- 配置Spring主配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:conf/applicationContext.xml</param-value>
	</context-param>
	
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<servlet>
		<servlet-name>spring-mvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>spring-mvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>

第八步：配置Mybatis主配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "mybatis-3-config.dtd" >
<configuration>
	<typeAliases>
		<typeAlias type="com.zhiyuan.pojo.Member" alias="member"/>
		<typeAlias type="com.zhiyuan.pojo.Consume" alias="consume"/>
	</typeAliases>
</configuration>

第九步：配置Spring主配置文件

<?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:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jdbc="http://www.springframework.org/schema/jdbc"
	xmlns:jee="http://www.springframework.org/schema/jee"
	xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
		http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd
		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-3.0.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"
		default-autowire="byName" default-lazy-init="false">
<!-- 配置JDBC数据库连接 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
	<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
	<property name="url" value="jdbc:mysql://127.0.0.1:3306/tests"></property>
	<property name="username" value="root"></property>
	<property name="password" value="liuxi"></property>
</bean>
<!-- 事务管理，管理数据库 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
	<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置映射文件和Mybatis主配置文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<property name="dataSource" ref="dataSource"></property>
	<property name="configLocation" value="classpath:conf/config.xml"></property>
	<property name="mapperLocations" value="classpath*:com/zhiyuan/mapper/*.xml"></property>
</bean>
<!-- 加載映射文件 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	<property name="basePackage" value="com.zhiyuan.mapper"></property>
</bean>
</beans>

第十步：创建一个JSP文件获取值，该JSP文件名必须与Controller类中实例化ModelAndView给他的参数名一样

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
     <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
     <%@ page import="com.zhiyuan.pojo.*" %>
     <%@ page import="java.util.*" %>
<!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>获取信息</title>
</head>
<body>
	<h1 style="font-family:华文行楷">用户信息表</h1>
	<table border="1px" style="border-collapse:collapse;width:400px;height:200px;text-align:center">
		<tr>
		<td>用戶名</td>
		<td>消费金额</td>
		<td>消费类型</td>
		<td>服务项目</td>
		<td>保修时间</td>
		</tr>
		
		<%
			List<Consume> consume=(List<Consume>)request.getAttribute("consume");
			for(Consume cs:consume){
				String name=cs.getC_name();
				int money=cs.getMoney();
				String goods=cs.getGoods();
				String servers=cs.getServers();
				String content=cs.getContent();
		
		%>
		<tr>
			<td><%=name %></td>
			<td><%=money %></td>
			<td><%=goods %></td>
			<td><%=servers %></td>   
			<td><%=content %></td>
		</tr>
		<%
			}
		%>
	</table>
</body>
</html>

最后结果：
