使用SpringBoot、redis、mybatis、MySQL、jwt、Result、security、thymeleaf、mail实现用户登录、注册、忘记密码功能的具体代码

这个问题的答案比较长，我不能在这里给出完整的代码。但是我可以提供一些指导和示例代码。

首先，您需要设置SpringBoot应用程序并添加所需的依赖项。以下是一个基本的pom.xml示例，其中包括所需的依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>

    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.3.2</version>
    </dependency>

    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>3.6.0</version>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.23</version>
    </dependency>

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-api</artifactId>
        <version>0.11.2</version>
    </dependency>

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-impl</artifactId>
        <version>0.11.2</version>
        <scope>runtime</scope>
    </dependency>

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-jackson</artifactId>
        <version>0.11.2</version>
        <scope>runtime</scope>
    </dependency>
</dependencies>

接下来，您需要创建一个用户模型，用于存储用户的信息。示例代码如下：

public class User {
    private Long id;
    private String username;
    private String password;
    private String email;
    // Getters and setters
}

然后，您需要创建一个MyBatis映射器来处理与数据库相关的操作。示例代码如下：

@Mapper
public interface UserMapper {
    @Select("SELECT * FROM users WHERE username=#{username}")
    User getUserByUsername(String username);

    @Insert("INSERT INTO users (username, password, email) VALUES (#{username}, #{password}, #{email})")
    void insertUser(User user);

    @Update("UPDATE users SET password=#{password} WHERE username=#{username}")
    void updatePassword(String username, String password);
}

然后，您需要创建一个SpringBoot控制器来处理用户登录、注册和忘记密码。以下是示例代码：

@Controller
public class UserController {
    @Autowired
    private UserMapper userMapper;

    @GetMapping("/login")
    public String login() {
        return "login";
    }

    @PostMapping("/login")
    public String doLogin(@RequestParam String username, @RequestParam String password, HttpSession session) {
        User user = userMapper.getUserByUsername(username);
        if (user != null && user.getPassword().equals(password)) {
            session.setAttribute("user", user);
            return "redirect:/";
        } else {
            return "login";
        }
    }

    @GetMapping("/register")
    public String register() {
        return "register";
    }

    @PostMapping("/register")
    public String doRegister(@ModelAttribute User user) {
        userMapper.insertUser(user);
        return "redirect:/login";
    }

    @GetMapping("/forgot-password")
    public String forgotPassword() {
        return "forgot-password";
    }

    @PostMapping("/forgot-password")
    public String doForgotPassword(@RequestParam String username, @RequestParam String email) {
        User user = userMapper.getUserByUsername(username);
        if (user != null && user.getEmail().equals(email)) {
            // Send email with password reset link
            return "password-reset-sent";
        } else {
            return "forgot-password";
        }
    }

    @GetMapping("/password-reset/{token}")
    public String resetPassword(@PathVariable String token) {
        // Verify token and show password reset form
        return "password-reset";
    }

    @PostMapping("/password-reset/{token}")
    public String doResetPassword(@PathVariable String token, @RequestParam String password) {
        // Reset password and redirect to login page
        return "redirect:/login";
    }
}

最后，您需要创建一个Thymeleaf模板来渲染登录、注册和忘记密码页面。以下是示例代码：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Login</title>
</head>
<body>
    <h1>Login</h1>
    <form method="post" action="/login">
        <div>
            <label for="username">Username:</label>
            <input type="text" name="username" id="username" required>
        </div>
        <div>
            <label for="password">Password:</label>
            <input type="password" name="password" id="password" required>
        </div>
        <button type="submit">Login</button>
    </form>
</body>
</html>

您可以使用类似的方式创建其他Thymeleaf模板。

这只是一个基本的示例，您需要根据您的具体需求进行修改。此外，您需要在应用程序中添加安全性和电子邮件配置等其他配置。
