springboot+redis验证码登录功能

好的,以下是Spring Boot Redis验证码登录功能的基本步骤:
1. 首先在Spring Boot项目中添加依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
```
2. 创建一个Redis配置类,并配置Redis连接信息:
```java
@Configuration
public class RedisConfig {
@Bean
public RedisConnectionFactory redisConnectionFactory() {
return new LettuceConnectionFactory(new RedisStandaloneConfiguration("localhost", 6379));
}
@Bean
public RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(redisConnectionFactory());
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return redisTemplate;
}
}
```
3. 创建一个用户实体类,并添加相应的字段:
```java
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private String username;
private String password;
private String email;
private String verificationCode;
}
```
4. 创建一个验证码登录控制器,并在其中添加验证码生成和校验逻辑:
```java
@RestController
public class VerificationCodeLoginController {
private final RedisTemplate<String, Object> redisTemplate;
public VerificationCodeLoginController(RedisTemplate<String, Object> redisTemplate) {
this.redisTemplate = redisTemplate;
}
@PostMapping("/login")
public String login(@RequestParam String username,
@RequestParam String password,
@RequestParam String verificationCode) {
User user = new User(username, password, null, verificationCode);
Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<User>> violations = validator.validate(user);
if (!violations.isEmpty()) {
return "Invalid user information.";
}
// Get the verification code from Redis.
String key = "verification_code:" + username;
String storedVerificationCode = (String) redisTemplate.opsForValue().get(key);
if (storedVerificationCode == null || !storedVerificationCode.equals(verificationCode)) {
return "Invalid verification code.";
}
// Remove the verification code from Redis.
redisTemplate.delete(key);
// Log the user in.
// ...
return "Login successful.";
}
@GetMapping("/verification-code")
public String getVerificationCode(@RequestParam String username) {
// Generate a random verification code.
String verificationCode = RandomStringUtils.randomNumeric(6);
// Save the verification code to Redis.
String key = "verification_code:" + username;
redisTemplate.opsForValue().set(key, verificationCode, 5, TimeUnit.MINUTES);
// Return the verification code.
return verificationCode;
}
}
```
在以上代码中,`login()`方法用于校验用户名、密码和验证码,并根据校验结果执行登录逻辑。在校验过程中,它首先从Redis中获取该用户的验证码,并与传入的验证码进行比较。如果两者不一致,则返回“Invalid verification code.”,否则从Redis中删除验证码,并执行登录逻辑。`getVerificationCode()`方法
