2、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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    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>Archetype Created Web Application</display-name>

    <!-- Spring 配置文件路径，此处可将Spring MVC的相关配置内容配置到Spring的配置文件applicationContext.xml中，共享同一个配置文件即可 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
    </context-param>

    <!-- Spring 监听器 配置 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

    <!-- 字符集 过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>

    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- Spring mvc 配置，配置文件名称默认为{servlet-name}-servlet.xml，路径默认在/WEB-INF/下 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

3、Spring MVC 配置文件，路径在/WEB-INF/下，springmvc-servlet.xml，里面包括freemarker的配置内容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

        http://www.springframework.org/schema/mvc   
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd   
        http://www.springframework.org/schema/tx   
        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd" >

    <context:component-scan base-package="com.hf.controller" /> 

    <mvc:annotation-driven />

    <!-- <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="suffix" value=".jsp" />
    </bean> -->
    <mvc:resources mapping="/**" location="/"/>
    
    <!-- ===================================================== -->
    <!-- ViewResolver For FreeMarker -->
    <!-- ===================================================== -->
    <bean id="freemarkerResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

        </property>
        <property name="freemarkerSettings"><!-- 设置FreeMarker环境属性 -->
            <props>
                <prop key="template_update_delay">5</prop><!--刷新模板的周期，单位为秒 -->

            </props>
        </property>
    </bean>
    
</beans>

4、applicationContext.xml，此处省略dataSource.properties配置的数据库连接的内容

<?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:p="http://www.springframework.org/schema/p"
    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-2.5.xsd  
                        http://www.springframework.org/schema/context  
                        http://www.springframework.org/schema/context/spring-context-2.5.xsd  
                        http://www.springframework.org/schema/mvc  
                        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
                        
    <!-- 扫描com.hf包里下的所有class文件，配置注解的类全都装入容器中进行管理 -->
    <context:component-scan base-package="com.hf" />
    <!-- 添加注解驱动 -->
    <mvc:annotation-driven />
    <!-- 引入jdbc配置文件 -->
    <context:property-placeholder location="classpath:dataSource.properties" />

    <!--创建jdbc数据源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${driver}" />
        <property name="url" value="${url}" />
        <property name="username" value="${username}" />
        <property name="password" value="${password}" />
    </bean>

    <!-- 配置事务管理  -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 创建SqlSessionFactory，并指定数据源 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="configLocation" value="classpath:mybatis-config.xml" />
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- Mapper文件扫描配置工具，Spring将自动扫描对应配置路径下的Mapper -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="classpath:" />
    </bean>

    <!-- MapperFactoryBean 创建的代理类实现了IUserDAO接口,并且注入到应用程序中，这样不用写实现类 -->
    <bean id="userDAO" class="org.mybatis.spring.mapper.MapperFactoryBean">
        <property name="mapperInterface" value="com.hf.idao.IUserDAO" />
        <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    </bean>

</beans>

5、Mybatis的相关配置文件

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

<!-- 配置映射文件   -->
<configuration>
    <mappers>
    <!--映射文件-->
       <mapper resource="user.xml"/>
    </mappers>
</configuration>

映射文件，user.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.hf.idao.IUserDAO">

    <resultMap type="com.hf.model.UserDo" id="UserDo" autoMapping="true">  
        <id property="id" column="id"/>  
        <result property="username" column="username"/>
        <result property="password" column="password"/>   
    </resultMap> 
  
    <select id="findAllUser" resultMap="UserDo">  
        select * from w_user  
    </select>  
      
     
</mapper>

6、业务代码

model层

package com.hf.model;

import java.io.Serializable;

public class UserDo implements Serializable {

    private int id ;
    private String username ;
    private String password ;
    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 getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
}

dao层

package com.hf.idao;

import java.util.List;

import com.hf.model.UserDo;



public interface IUserDAO {

    public List<UserDo> findAllUser() ;
}

service层

package com.hf.iservice;

import java.util.List;

import com.hf.model.UserDo;



public interface IUserService {

    public List<UserDo> findAllUser() ;
}

package com.hf.service;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.hf.idao.IUserDAO;
import com.hf.iservice.IUserService;
import com.hf.model.UserDo;

@Service("userService")
public class UserService implements IUserService {
    
    @Autowired
    private IUserDAO userDAO ;

    @Override
    public List<UserDo> findAllUser() {
        return userDAO.findAllUser();
    }

}

controller层

package com.hf.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import com.hf.iservice.IUserService;
import com.hf.model.UserDo;

@Controller
public class UserController {

    @Autowired
    private IUserService userService ;
    
    @RequestMapping("/User/helloUser")
    public String helloUser(ModelMap modelMap) {
        List<UserDo> list = this.userService.findAllUser();
        modelMap.addAttribute("userDo", list) ;
        return "/user_list";
    }
}

views层文件user_list.ftl：
