spring实现注册（邮箱验证+有效时间）
spring实现注册（邮箱验证+有效时间）
实现逻辑
用户注册时，输入邮箱地址，获取验证码，我们随机生成5位数字验证码发送给用户的邮箱。同时我们把验证码和当前时间存储到HttpSession对象中(格式 ： 验证码#时间)。
然后用户通过表单提交自己的注册信息和验证码。我们先判断用户名是否重复（为空和密码一致就交给前端吧），然后我们从session中取出我们存储的字符串分隔，获取验证码和生成验证码的时间，先比较验证码是否正确，如果正确就比较时间是否在一段时间内，都符合才注册（进行数据库操作）。
代码实现尊崇ssh框架结构，action，service，dao逐层调用。
1：引入jar包
spring自带的包 spring-context-support, 就可以使用spring自带的发送邮件API。
2：创建MailUtil对象
import java.util.Properties;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
public class MailUtil {
//使用对象注入的方式 记得配置文件
private JavaMailSenderImpl senderImpl;
public void setSenderImpl(JavaMailSenderImpl senderImpl) {
this.senderImpl = senderImpl;
}
private SimpleMailMessage mailMessage;
public void setMailMessage(SimpleMailMessage mailMessage) {
this.mailMessage = mailMessage;
}
private Properties prop;
public void setProp(Properties prop) {
this.prop = prop;
}
//发送验证码的方法,to是目标邮箱地址，text是发送的验证码（事先生成）
public boolean sendMail (String to,String text) {
System.out.println("sendMail...util...");
try{
//设定mail server
senderImpl.setHost("smtp.163.com");
// 设置收件人，寄件人 用数组发送多个邮件
// String[] array = new String[] {"[email protected]","[email protected]"};
// mailMessage.setTo(array);
mailMessage.setTo(to);
mailMessage.setFrom( "自己的邮箱" );
mailMessage.setSubject( "主题" );
mailMessage.setText("内容" + text);
senderImpl.setUsername("自己的邮箱");
senderImpl.setPassword("密码");
prop.put("mail.smtp.auth","true");
prop.put("mail.smtp.timeout","25000");
senderImpl.setJavaMailProperties(prop);
//发送邮件
senderImpl.send(mailMessage);
System.out.println("发送邮件成功");
return true;
}catch (Exception e) {
System.out.println("发送邮件失败");
return false;
}
}
}
3：创建TimeUtil类
因为我们是保证有效时间的，所以就要时间工具
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import org.junit.Test;
public class TimeUtil {
//获取时间 返回毫秒级时间
public String getTime() {
System.out.println("getTime...util...");
//SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Calendar calendar = Calendar.getInstance();
Long date = calendar.getTime().getTime(); //获取毫秒时间
//String dateStringPaString = sdf.format(date);
//System.out.println(dateStringPaString);
return date.toString();
}
public boolean cmpTime(String time) {
System.out.println("cmpTime...util...");
long tempTime = Long.parseLong(time);
System.out.println("tempTime"+tempTime);
//在获取现在的时间
Calendar calendar = Calendar.getInstance();
Long date = calendar.getTime().getTime(); //获取毫秒时间
System.out.println("date"+date);
if(date - tempTime > 600000 ) { //10分钟
return false;
} else {
return true;
}
}
}4：Action
//获取邮箱验证码
public String getVCode() throws IOException {
System.out.println("getVCode...action...");
//获得request和response对象
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("application/json;charset=utf-8");
response.setHeader("Access-Control-Allow-Origin", "*");
PrintWriter out = response.getWriter();
JSONObject json = new JSONObject();
try{
String email = request.getParameter("email");
boolean flag = userService.getVCode(email);
if(flag == true) {
json.put("msg","1"); //生成了验证码并发送给了用户
} else {
json.put("msg","0"); //未获取到
}
}catch (Exception e) {
json.put("msg","0");
}finally {
out.write(json.toString());
out.flush();
out.close();
}
return null;
}
//用户注册
public String register() throws IOException {
System.out.println("register...action...");
//获得request和response对象
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("application/json;charset=utf-8");
response.setHeader("Access-Control-Allow-Origin", "*");
PrintWriter out = response.getWriter();
JSONObject json = new JSONObject();
try{
String username = request.getParameter("username");
String password = request.getParameter("password");
String nickname = request.getParameter("nickname");
String email = request.getParameter("email");
String vcode = request.getParameter("vcode");
//先查找该用户名是否被注册
boolean flag = userService.searchUser(username);
if(flag == true) {
json.put("msg","3"); //用户名重复
} else {
//看验证码是否正确以及是否失效
flag = userService.cmpVCode(vcode);
if(flag == true){
User user = new User();
user.setUsername(username);
user.setPassword(password);
user.setNickname(nickname);
user.setEmail(email);
boolean flag2 =userService.register(user);
if(flag2 == true) {
json.put("msg", "1"); //注册成功
} else {
json.put("msg","0"); //注册失败
}
} else {
System.out.println("验证码匹配失败");
json.put("msg", "0"); //验证码匹配失败
}
}
} catch(Exception e) {
System.out.println("注册异常");
json.put("msg", "0"); //注册 异常
} finally {
out.write(json.toString());
out.flush();
out.close();
}
return null;
}5：service
//发送邮件获取验证码
public boolean getVCode(String email) {
System.out.println("getVCode...service...");
//随机生成5验证码
Integer x =(int)((Math.random()*9+1)*10000);
String text = x.toString();
boolean flag = mailUtil.sendMail(email, text);
if(flag == true){
//发送成功，把验证码和时间记录
String nowTime = timeUtil.getTime();
//存入session 验证码#时间
HttpSession session = ServletActionContext.getRequest().getSession();
session.setAttribute("vcodeTime",text+"#"+nowTime);
System.out.println(session.getAttribute("vcodeTime"));
return true;
} else {
return false;
}
}
//比较验证码是否正确以及是否失效
public boolean cmpVCode(String vcode) {
System.out.println("cmpVCode...service...");
try{
HttpSession session = ServletActionContext.getRequest().getSession();
String vcodeTime = (String) session.getAttribute("vcodeTime");
String vcodeTimeArray[] = vcodeTime.split("#");
//先比较验证码是否正确
if(vcodeTimeArray[0].equals(vcode)) {
boolean flag = timeUtil.cmpTime(vcodeTimeArray[1]);
if(flag == true){
return true;
}
}
return false;
} catch (Exception e) {
System.out.println(e.toString());
return false;
}
}
//注册
public boolean register(User user) {
System.out.println("register...service...");
int flag = userDao.addUser(user);
if(flag != 0) {
HttpSession session = ServletActionContext.getRequest().getSession();
session.setAttribute("uid", flag); //用户id放入 session
return true;
} else {
return false;
}
}6：dao
//添加用户
public int addUser(User user) {
System.out.println("addUser...dao...");
try{
int flag = (int)hibernateTemplate.save(user);
System.out.println("save后返回的flag值" + flag);
return flag;
}catch (Exception e) {
System.out.println(e.toString());
return 0;
}
}
