springboot+html实现简单注册登录

下面是一个简单的Spring Boot和HTML结合实现注册和登录的例子。

首先，你需要创建一个Spring Boot项目并添加相关依赖，比如spring-boot-starter-web和thymeleaf。




<!-- pom.xml -->
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
</dependencies>

然后，创建控制器来处理注册和登录的请求。




// RegistrationController.java
@Controller
public class RegistrationController {
 
    @GetMapping("/register")
    public String registerForm(Model model) {
        model.addAttribute("user", new User());
        return "register";
    }
 
    @PostMapping("/register")
    public String registerSubmit(@ModelAttribute User user) {
        // 这里应该是将用户信息保存到数据库的逻辑
        return "redirect:/login";
    }
}
 
// LoginController.java
@Controller
public class LoginController {
 
    @GetMapping("/login")
    public String loginForm(Model model) {
        model.addAttribute("user", new User());
        return "login";
    }
 
    @PostMapping("/login")
    public String loginSubmit(@ModelAttribute User user) {
        // 这里应该是验证用户信息的逻辑
        return "home";
    }
}

接下来，创建注册和登录的HTML模板。




<!-- register.html -->
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Register</title>
</head>
<body>
    <form action="/register" method="post">
        <div>
            <label>Username:</label>
            <input type="text" th:field="*{username}" />
        </div>
        <div>
            <label>Password:</label>
            <input type="password" th:field="*{password}" />
        </div>
        <div>
            <input type="submit" value="Register" />
        </div>
    </form>
</body>
</html>




<!-- login.html -->
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Login</title>
</head>
<body>
    <form action="/login" method="post">
        <div>
            <label>Username:</label>
            <input type="text" th:field="*{username}" />
        </div>
        <div>
            <label>Password:</label>
            <input type="password" th:fi
