如果你按照上一章节的来的话，你现在的目录结构应该是这样的：

下面继续：

一、填充mybatis的配置文件

AccountMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xupeng.mapper.AccountMapper">
    <insert id="save" parameterType="account">
        insert into account values (#{id},#{name},#{money})
    </insert>

    <select id="findAll" resultType="account">
        select * from account
    </select>

</mapper>

sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <!--加载properties文件-->
    <properties resource="jdbc.properties"></properties>

    <!--定义别名-->
    <typeAliases>
        <!--<typeAlias type="com.xupeng.domain.Account" alias="account"></typeAlias>-->
        <!--给这个包下所有实体设置别名。别名是首字母小写，或者首字母都行-->
        <package name="com.xupeng.domain"/>
    </typeAliases>

    <!--环境-->
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>

    <!--加载映射文件-->
    <mappers>
        <!--<mapper resource="com/xupeng/mapper/AccountMapper.xml"></mapper>-->
        <package name="com.xupeng.mapper"/>
    </mappers>

</configuration>

二、填充spring，springmvc配置文件

applicationContext.xml

<?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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="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.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd
                        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--组件扫描，扫描service和mapper-->
    <context:component-scan base-package="com.xupeng">
        <!--排除controller，因为springmvc有扫了-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter>
    </context:component-scan>
</beans>

spring-mvc.xml

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="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.xsd
                            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--组件扫描，扫描controller-->
    <context:component-scan base-package="com.xupeng.controller"></context:component-scan>

    <!--配置mvc注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!--内部资源视图解析器-->
    <bean id="resourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

    <!--开放静态资源访问权限-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>

</beans>

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_2_5.xsd" id="WebApp_ID" version="2.5">

  <!--监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!--springmvc前端控制器-->
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--乱码过滤器-->
  <filter>
    <filter-name>CharacterEncodingFilter</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>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

三、业务代码

AccountController

package com.xupeng.controller;

import com.xupeng.domain.Account;
import com.xupeng.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    //保存
    @RequestMapping("/save")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return "成功";
    }

    //查询
    public ModelAndView findAll(){
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList",accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}

AccountServiceImpl

package com.xupeng.controller;

import com.xupeng.domain.Account;
import com.xupeng.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    //保存
    @RequestMapping(value = "/save",produces = "text/html;charset=utf-8")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return "成功";
    }

    //查询
    @RequestMapping(value = "/findAll")
    public ModelAndView findAll(){
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList",accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}
