发送邮件
邮箱设置
springEmail
properties
spring.mail.host=smtp.qq.com
spring.mail.port=465
spring.mail.username=
spring.mail.password=
spring.mail.protocol=smtps
spring.mail.properties.mail.smtp.ssl.enable=trueMailClient
@Component
public class MailClient {
private static final Logger logger = LoggerFactory.getLogger(MailClient.class);
@Autowired
private JavaMailSender mailSender;
@Value("${spring.mail.username}")
private String from;
public void sendMail(String to, String subject, String content){
try {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
mailSender.send(helper.getMimeMessage());
} catch (MessagingException e) {
logger.error("发件邮件失败" + e.getMessage());
}
}
}
先初始化message，然后把message交给helper
helper可以设置发送方from，接收方to，标题subject，内容content，true是表示能不能接收html文件
然后用mailSender.send来发送邮件
MailTest
@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = CommunityApplication.class)
public class MailTests {
@Autowired
private MailClient mailClient;
@Test
public void testTextMail(){
mailClient.sendMail("", "TEST", "Welcome");
}
}模版引擎：发送html
MailTest
@Autowired
private MailClient mailClient;
@Autowired
private TemplateEngine templateEngine;
@Test
public void textHtmlMail(){
Context context = new Context();
context.setVariable("username", "sunday");
String content = templateEngine.process("/mail/demo", context);
System.out.println(content);
mailClient.sendMail("", "HTML", content);
}先把username值传到html文件中，然后拼接出来，最后传content这个html文件，helper那里设置成了true
开发注册功能
访问注册页面
点击顶部区域内的链接，打开注册页面
直接由controller调用模板，响应html页面就可以
LoginController.java
@RequestMapping(path = "/register", method = RequestMethod.GET)
public String getRegisterPage() {
return "/site/register";
register.html
改一下
<html lang="en" xmlns:th="http://www.thymeleaf.org">
改一下css和js的数据格式
<link rel="stylesheet" th:href="@{/css/global.css}" />
<link rel="stylesheet" th:href="@{/css/login.css}" />
index.html
可以通过header复用
在register.html复用
提交注册数据
前期准备
引入判断空值什么的包
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.9</version>
</dependency>把链接做成可配置的，在properties里面
community.path.domain=http://localhost:8080写一个工具类，用于生成随机字符串和md5加密
服务端验证账号是否已存在、邮箱是否已注册
注册是对用户表进行操作->操作UserService层
通过表单提交数据
服务端发送激活邮件
UserService.java
LoginController.java
@RequestMapping(path = "/register", method = RequestMethod.POST)
public String register(Model model, User user) {
Map<String, Object> map = userService.register(user);
if (map == null || map.isEmpty()) {
model.addAttribute("msg", "注册成功,我们已经向您的邮箱发送了一封激活邮件,请尽快激活!");
model.addAttribute("target", "/index");
return "/site/operate-result"; // 成功之后return到一个第三方页面
} else {
model.addAttribute("usernameMsg", map.get("usernameMsg"));
model.addAttribute("passwordMsg", map.get("passwordMsg"));
model.addAttribute("emailMsg", map.get("emailMsg"));
return "/site/register";
}
}operate-result.html
<!-- 内容 -->
<div class="main">
<div class="container mt-5">
<div class="jumbotron">
<p class="lead" th:text="${msg}">您的账号已经激活成功,可以正常使用了!</p>

th:value="${user!=null?user.username:''}"

</div>
</div>
</form>
</div>
</div>确定表单的提交方式
每一个框都要有相应的name，这些name要和controller中user对象的属性名对应
如果usernameMsg是非空的就加上is-invalid
因为如果usernameMsg是空的话，说明没错误，下面的div就显示不出来，有一个连带关系
激活注册账号
点击邮件中的链接，访问服务端的激活服务
已经发送链接之后，说明前面注册的功能已经完成了，现在要对一个url进行验证，有三种情况：
- 激活成功
- 这个链接已经被验证过
- 无效链接
现在util包里面写出激活的三个常量
public interface CommunityConstant {
/**
* 激活成功
*/
int ACTIVATION_SUCCESS = 0;
/**
* 重复激活
*/
int ACTIVATION_REPEAT = 1;
/**
* 激活失败
*/
int ACTIVATION_FAILURE = 2;
}这三个变量有什么卵用呢？为什么三个常量还要给一个高大上的名字呢？
userservice
public int activation(int userId, String code) {
User user = userMapper.selectById(userId);
if (user.getStatus() == 1) {
return ACTIVATION_REPEAT;
} else if (user.getActivationCode().equals(code)) {
userMapper.updateStatus(userId, 1);
return ACTIVATION_SUCCESS;
} else {
return ACTIVATION_FAILURE;
}
}这个函数是通过controller层的userid和那个user对应的生成的code，从数据库中看那个user的status属性，如果是1的话，就说明重复添加了，返回repeat；如果user的status初始值是0，而且它传入的code和数据库里面user的code是一样的话，就说明还没有被激活，此时就要把这个status设成1，返回success；如果code不一样，就说明是一个假冒伪劣网址，就要返回failure
loginController
// http://localhost:8080/community/activation/101/code
@RequestMapping(path = "/activation/{userId}/{code}", method = RequestMethod.GET)
public String activation(Model model, @PathVariable("userId") int userId, @PathVariable("code") String code) {
int result = userService.activation(userId, code);
if (result == ACTIVATION_SUCCESS) {
model.addAttribute("msg", "激活成功,您的账号已经可以正常使用了!");
model.addAttribute("target", "/login");
} else if (result == ACTIVATION_REPEAT) {
model.addAttribute("msg", "无效操作,该账号已经激活过了!");
model.addAttribute("target", "/index");
} else {
model.addAttribute("msg", "激活失败,您提供的激活码不正确!");
model.addAttribute("target", "/index");
}
return "/site/operate-result";
}这个controller就要从service层获取activation方法值了，传递的是ul里面的userid和code，这个url是由上面userservice层拼出来的
