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.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://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.xsdhttp://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://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>
