SSH综合项目实战（快递） -- day08 邮箱激活、用户登录、city-picker

一、客户邮箱激活

1、引入JavaMail的jar包坐标

2、复制邮件工具类到前台系统工具类包中

package com.itheima.bos_fore.utils;

import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

public class MailUtils {
	private static String smtp_host = "smtp.126.com"; 
	private static String username = "[email protected]"; 
	private static String password = "147963qP"; 

	private static String from = "[email protected]"; // 使用当前账户
	public static String activeUrl = "http://localhost:8082/bos_fore/customerAction_activeMail";

	public static void sendMail(String subject, String content, String to) {
		Properties props = new Properties();
		props.setProperty("mail.smtp.host", smtp_host);
		props.setProperty("mail.transport.protocol", "smtp");
		props.setProperty("mail.smtp.auth", "true");
		Session session = Session.getInstance(props);
		Message message = new MimeMessage(session);
		try {
			message.setFrom(new InternetAddress(from));
			message.setRecipient(RecipientType.TO, new InternetAddress(to));
			message.setSubject(subject);
			message.setContent(content, "text/html;charset=utf-8");
			Transport transport = session.getTransport();
			transport.connect(smtp_host, username, password);
			transport.sendMessage(message, message.getAllRecipients());
		} catch (Exception e) {
			e.printStackTrace();
			throw new RuntimeException("邮件发送失败...");
		}
	}

	public static void main(String[] args) {
		sendMail("测试邮件", "你好，传智播客", "[email protected]");
	}
}

3、redis的安装使用

（1）、解压windows版本的redis压缩包并启动

（2）、在项目中引入jedis的jar包坐标

（3）、编写测试类测试jedis

package bos_fore;

import org.junit.Test;

import redis.clients.jedis.Jedis;

public class JedisClientTest {

	@Test
	public void testJedis(){
		Jedis jedis = new Jedis("localhost");
		//存
		jedis.set("key1", "value1");
		jedis.set("key2", "value2");
		//取
		String value1 = jedis.get("key1");
		System.out.println(value1);
		//删
		jedis.del("value1");
	}
}

4、spring data redis的使用

（1）、引入jar包坐标

（2）、在前台项目的spring配置文件中加入jedis的配置

（3）、spring整合redis测试

package bos_fore;

import java.util.concurrent.TimeUnit;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class JedisClientTest {

	@Autowired
	private RedisTemplate redisTemplate;
	
	@Test
	public void testJedis(){
		//增
		redisTemplate.opsForValue().set("key3", "value3");
		//增加并设置超时时间
		redisTemplate.opsForValue().set("key4", "value4", 8, TimeUnit.SECONDS);//设置超时时间为8s
		//删
		redisTemplate.delete("key3");
	}
}

5、完善CustomerAction中客户注册时发送激活邮件

6、客户端邮箱激活操作

（1）、编写CRM系统中CustomerService上激活邮件的方法

	/**
	 * 用户激活的方法
	 * @param telephone
	 */
	public void activeMail(String telephone) {
		dao.activeMail(telephone);
	}

	/**
	 * 根据手机号查询客户信息
	 */
	public Customer findCustomerByTelephone(String telephone) {
		return dao.findByTelephone(telephone);
	}

（2）、编写CRM中dao层代码

	/**
	 * 用户激活的方法
	 * @param telephone
	 */
	@Query("update Customer set type = 1 where telephone = ?")
	@Modifying
	public void activeMail(String telephone);

	/**
	 * 根据手机号查询客户信息
	 */
	public Customer findByTelephone(String telephone);

（3）、重新生成CRM的客户端代码

（4）、在CustomerAction中提供激活邮件的方法

	// 属性驱动，接收页面传递的激活码
	private String activeCode;

	public void setActiveCode(String activeCode) {
		this.activeCode = activeCode;
	}

	@Action(value="customerAction_activeMail",results={
			@Result(name="success",type="redirect", location="/active-success.html"),
			@Result(name="error",type="redirect", location="/active-fail.html"),
			@Result(name="hasBind",type="redirect", location="/active-has.html")
	})
	public String activeCode(){
		//获取手机号
		String phone = model.getTelephone();
		//从redis中获取激活吗
		String redisActiveCode = redisTemplate.opsForValue().get(phone);
		if(redisActiveCode != null && phone != null && redisActiveCode.equals(activeCode)){
			//提供的激活码正确，判断用户是否已经激活
			Customer customer = service.findCustomerByTelephone(phone);
			if(customer.getType() == null || customer.getType() != 1){
				//调用crm完成激活操作
				service.activeMail(phone);
				//清除redis中的激活码
				redisTemplate.delete(phone);
				return SUCCESS;
			}else{
				//用户已经激活，跳转到一个页面
				return "hasBind";
			}
		}
		return ERROR;
	}

二、前台系统客户登录

1、登录页面生成验证码的validatecode.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ page import="java.util.Random"%>
<%@ page import="java.io.OutputStream"%>
<%@ page import="java.awt.Color"%>
<%@ page import="java.awt.Font"%>
<%@ page import="java.awt.Graphics"%>
<%@ page import="java.awt.image.BufferedImage"%>
<%@ page import="javax.imageio.ImageIO"%>
<%
	int width = 80;
	int height = 32;
	//create the image
	BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
	Graphics g = image.getGraphics();
	// set the background color
	g.setColor(new Color(0xDCDCDC));
	g.fillRect(0, 0, width, height);
	// draw the border
	g.setColor(Color.black);
	g.drawRect(0, 0, width - 1, height - 1);
	// create a random instance to generate the codes
	Random rdm = new Random();
	String hash1 = Integer.toHexString(rdm.nextInt());
	// make some confusion
	for (int i = 0; i < 50; i++) {
		int x = rdm.nextInt(width);
		int y = rdm.nextInt(height);
		g.drawOval(x, y, 0, 0);
	}
	// generate a random code
	String capstr = hash1.substring(0, 4);
	//将生成的验证码存入sesison中
	session.setAttribute("validateCode", capstr);
	//设置验证码的颜色
	g.setColor(new Color(0, 100, 0));
	//设置字体
	g.setFont(new Font("Candara", Font.BOLD, 24));
	g.drawString(capstr, 8, 24);
	g.dispose();
	response.setContentType("image/jpeg");
	out.clear();
	out = pageContext.pushBody();
	OutputStream strm = response.getOutputStream();
	ImageIO.write(image, "jpeg", strm);
	strm.close();
%>

2、添加点击验证码图片，重新加载验证码的事件

3、添加form表单的提交地址

4、扩展CRM系统中用户登录的方法

（1）、service层

	/**
	 * 用户登录的方法
	 * @param telephone
	 * @param password
	 * @return
	 */
	public Customer login(String telephone, String password) {
		return dao.findByTelephoneAndPassword(telephone,password);
	}

（2）、dao层

	/**
	 * 用户登录的方法
	 * @param telephone
	 * @param password
	 * @return
	 */
	public Customer findByTelephoneAndPassword(String telephone, String password);

5、编写用户登录的方法

	/**
	 * 客户登录的方法
	 */
	@Action(value="customerAction_login",results={
			@Result(name="home",type="redirect",location="/index.html"),
			@Result(name="login",type="redirect",location="/login.html")
	})
	public String login(){
		//获取手机号
		String telephone = model.getTelephone();
		//获取密码
		String password = model.getPassword();
		//从session中获取生成的验证码
		String validateCode = (String) ServletActionContext.getRequest().getSession().getAttribute("validateCode");
		//判断两个验证码是否相同
		if(StringUtils.isNotBlank(validateCode) && StringUtils.isNotBlank(checkcode) && checkcode.equals(validateCode)){
			//验证码相同，调用crm服务对象进行登录验证
			Customer customer = service.login(telephone, password);
			if(customer != null){
				//登录成功，将用户信息存入session中
				ServletActionContext.getRequest().getSession().setAttribute("loginCustomer", customer);
				return "home";
			}else{
				//登录失败，跳转回登录页面
				return LOGIN;
			}
		}
		return LOGIN;
	}

三、使用city-picker实现省市区三级联动

1、解压city-picker的压缩包

2、编写测试之 -- 使用html的方式

3、编写测试之 -- 使用js动态加载
