        <tx:annotation-driven transaction-manager="transactionManager"/>
    </beans>

3、spring-mvc.xml:

    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"> 
         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);
       }
    }
