springJDBC 中JdbcTemplate 类方法使用

一，Dao

IUserinfDao

package com.dkt.dao;

import java.util.List;

import com.dkt.entity.Userinfo;

public interface IUserinfDao {

	public int addUserinfo(Userinfo ui);
	//  查询返回的是map集合，一行数据一个map,直接去key为属性
	public List<Userinfo> queryUserinfo(Userinfo ui);
	public Userinfo queryUser(int i);
	
	public String queryUserphone(int id);//查询单个字段
	public int deleteUserinfo(int id);
}

UserinfDaoImpl 

package com.dkt.dao.impl;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.List;

import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;


import com.dkt.dao.IUserinfDao;
import com.dkt.entity.Userinfo;

public class UserinfDaoImpl extends JdbcTemplate implements IUserinfDao{

	public int addUserinfo(Userinfo ui) {
		 int i = super.update("insert into userinfo values(null,?,?,?,?,?)",
				new Object[]{ui.getUserphone(),ui.getUserpnike(),ui.getUserpwd(),ui.getUsergreate().intValue(),ui.getUserreagedate()});
		return i;
	}

	public List<Userinfo> queryUserinfo(Userinfo ui) {
		List<Userinfo> list = super.query("select * from userinfo where userphone='"+ui.getUserphone()+"'",
				new BeanPropertyRowMapper<Userinfo>(Userinfo.class));
		return list;
	}
	
	public int deleteUserinfo(int id) {
		int delete = super.update("delete from userinfo where userid= ? ", new Object[]{id});
		return delete;
	}

	public int updateUserinfo(Userinfo  ui) {
		int update = super.update("update userinfo set userpnike = ?  where userid= ? ", new Object[]{ui.getUserpnike(),ui.getUserid()});
		return update;
	}
	
	public String queryUserphone(int id) {
		String  i = super.queryForObject("select userphone from userinfo where userid=?", new Object[]{id},String.class);
		return i;
	}
	
	public Userinfo queryUser(int i) {
		return super.queryForObject(" select * from userinfo where userid=?",
				new Object[]{i},
//				new BeanPropertyRowMapper<Userinfo>(Userinfo.class)
				//  内部类实现得到对象
				new RowMapper<Userinfo>(){
					public Userinfo mapRow(ResultSet arg0, int arg1)
							throws SQLException {
						Userinfo userinfo = new Userinfo(arg0.getString("userphone"), 
								arg0.getString("userpwd"),
								arg0.getTimestamp("userreagedate"));
						return userinfo;
					}
		});
	}


	
}

二，entity

package com.dkt.entity;

import java.sql.Timestamp;

/**
 * Userinfo entity. @author MyEclipse Persistence Tools
 */

public class Userinfo implements java.io.Serializable {

	// Fields

	private Integer userid;
	private String userphone;
	private String userpnike;
	private String userpwd;
	private Integer usergreate;
	private Timestamp userreagedate;

	// Constructors

	/** default constructor */
	public Userinfo() {
	}

	/** minimal constructor */
	public Userinfo(String userphone, String userpwd, Timestamp userreagedate) {
		this.userphone = userphone;
		this.userpwd = userpwd;
		this.userreagedate = userreagedate;
	}

	public Userinfo(String userphone, String userpnike, String userpwd,
			Timestamp userreagedate) {
		super();
		this.userphone = userphone;
		this.userpnike = userpnike;
		this.userpwd = userpwd;
		this.userreagedate = userreagedate;
	}

	/** full constructor */
	public Userinfo(String userphone, String userpnike, String userpwd,
			Integer usergreate, Timestamp userreagedate) {
		this.userphone = userphone;
		this.userpnike = userpnike;
		this.userpwd = userpwd;
		this.usergreate = usergreate;
		this.userreagedate = userreagedate;
	}

	// Property accessors

	public Integer getUserid() {
		return this.userid;
	}

	public void setUserid(Integer userid) {
		this.userid = userid;
	}

	public String getUserphone() {
		return this.userphone;
	}

	public void setUserphone(String userphone) {
		this.userphone = userphone;
	}

	public String getUserpnike() {
		return this.userpnike;
	}

	public void setUserpnike(String userpnike) {
		this.userpnike = userpnike;
	}

	public String getUserpwd() {
		return this.userpwd;
	}

	public void setUserpwd(String userpwd) {
		this.userpwd = userpwd;
	}

	public Integer getUsergreate() {
		return this.usergreate;
	}

	public void setUsergreate(Integer usergreate) {
		this.usergreate = usergreate;
	}

	public Timestamp getUserreagedate() {
		return this.userreagedate;
	}

	public void setUserreagedate(Timestamp userreagedate) {
		this.userreagedate = userreagedate;
	}

}

三，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:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<bean id="ds" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName"><value>com.mysql.jdbc.Driver</value> </property>
	<property name="username"><value>root</value> </property>
	<property name="password"><value>123456</value>  </property>
	<property name="url"><value>jdbc:mysql://localhost:3306/marry?userUnicode=true&characterEncoding=utf-8</value>  </property>
</bean>

<bean id="userdao" class="com.dkt.dao.impl.UserinfDaoImpl">
	<property name="dataSource" ref="ds"></property>
</bean>

</beans>　

四，test

package com.dkt.test;

import java.sql.Timestamp;
import java.util.Date;
import java.util.List;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.dkt.dao.impl.UserinfDaoImpl;
import com.dkt.entity.Userinfo;


public class TsetJDBC {

	public static void main(String[] args) {
		
		BeanFactory bf = new ClassPathXmlApplicationContext("applicationContext.xml");
		UserinfDaoImpl udao = (UserinfDaoImpl)bf.getBean("userdao");
		/*int i = udao.addUserinfo(new Userinfo("13993723892", "小黑", "qewres",9,new Timestamp(new Date().getTime())));
		if (i>0) {
			System.out.println("添加成功");
		}*/
		Userinfo userinfo = new Userinfo();
		userinfo.setUserphone("13996932874");
		List<Userinfo> user = udao.queryUserinfo(userinfo);
		for (Userinfo userinfo2 : user) {
			System.out.println(userinfo2.getUserid());
		}
		
		/*Userinfo user2 = udao.queryUser(10);
		System.out.println(user2.getUserphone());*/
		
		/*int i = udao.deleteUserinfo(11);
		if (i>0) {
			System.out.println("删除成功");
		}*/
		/*System.out.println(udao.queryUserphone(10));
		
		Userinfo ui = new Userinfo();
		ui.setUserid(4);
		ui.setUserpnike("咳咳");
		int u = udao.updateUserinfo(ui);
		if (u>0) {
			System.out.println("更新成功");
		}*/
	}
}
