    <!-- 自动扫描 ，查找注解类-->
    <context:component-scan base-package="com.dw" ></context:component-scan>  
       
    <!-- 声明注解，否则需要将@Autowire等注册为spring bean ，当context:component-scan存在时可以省略-->
    <!-- <context:annotation-config/>  -->
    
    <!-- 加载数据源参数 -->
    <context:property-override location="classpath:jdbc.properties"/>
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

        <property name="dataSource" ref="dataSource" />
    </bean>    
    
    <!-- 启用支持 annotation 注解方式事物管理 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

3、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:p="http://www.springframework.org/schema/p"  
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:mvc="http://www.springframework.org/schema/mvc"

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc    
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  
    <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->  
    <context:component-scan base-package="com.dw.controller" />

    <!-- 定义跳转的文件的前后缀 ，视图模式配置-->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->  
        <property name="prefix" value="/WEB-INF/views/" />  
        <property name="suffix" value=".jsp" />  
    </bean>  
</beans>

4、mybatis.xml:

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

<configuration>
    <typeAliases>  <!-- 别名 -->
        <typeAlias type="com.dw.domain.Admin" alias="Admin"/>
    </typeAliases>
</configuration>

5、jdbc.properties：

dataSource.driverClass=com.mysql.jdbc.Driver
dataSource.jdbcUrl=jdbc:mysql://127.0.0.1:3306/db_vote?useUnicode=true&characterEncoding=UTF-8
dataSource.user=root
dataSource.password=root
dataSource.maxPoolSize=20
dataSource.maxIdleTime=1000
dataSource.minPoolSize=6
dataSource.initialPoolSize=5

6、log4j.properties：

log4j.rootLogger=INFO,Console  
   
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.Threshold=DEBUG  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%d]%l%5p:%m%n  
   
log4j.appender.DebugFile=org.apache.log4j.RollingFileAppender

log4j.logger.java.sql.PreparedStatement = DEBUG  
log4j.logger.java.sql.ResultSet = DEBUG  
   
log4j.logger.com.dw=DEBUG

7、pojo类：

package com.dw.domain;

import java.util.Date;

public class Admin {
	private Integer id;
	private String name;
	private String password;
	private Date logintime;

	public Admin() {
		super();
	}

	public Admin(String name, String password, Date logintime) {
		super();
		this.name = name;
		this.password = password;
		this.logintime = logintime;
	}

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public Date getLogintime() {
		return logintime;
	}

	public void setLogintime(Date logintime) {
		this.logintime = logintime;
	}

}

8、DAO 下 接口及mapper映射文件：

package com.dw.dao;

import com.dw.domain.Admin;

public interface AdminMapper {
   public int insertAdmin(Admin admin);
}

<?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.dw.dao.AdminMapper">
  <insert id="insertAdmin" parameterType="Admin"> <!-- Admin为别名 -->
     insert into t_admin(name,password,logintime) values(#{name},#{password},#{logintime});
  </insert>
</mapper>

9、service层：

package com.dw.service;

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

import com.dw.dao.AdminMapper;
import com.dw.domain.Admin;

@Service
public class AdminServiceImpl implements AdminService{
    @Autowired
    @Qualifier("adminMapper")
    //@Resource(name="adminMapper")
	private AdminMapper adminMapper;
	@Override
	public void addAdmin(Admin admin) {
		adminMapper.insertAdmin(admin);
	}
  
}

10、controller层:

package com.dw.controller;

import java.util.Date;

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

import com.dw.domain.Admin;
import com.dw.service.AdminService;

@Controller
@RequestMapping("/Admin")
public class AdminController {
   @Autowired
   private AdminService adminService;
   
   @RequestMapping("/toAdd.do")
   public void toAdd() {
	   Admin admin = new Admin("王五","123456",new Date());
	   adminService.addAdmin(admin);
   }
}
