1、pom文件

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>

<!-- 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>

<load-on-startup>1</load-on-startup>
</servlet>
<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"

</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"

<!-- 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 -->

</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">

<!-- 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 -->

<property name="mapperInterface" value="com.hf.idao.IUserDAO" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />

</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：
