SpringBoot项目中使用Redis，Mybatis和JWT

以下是一个简化的Spring Boot项目中整合Redis, MyBatis和JWT的示例：

1. 在pom.xml中添加依赖：

<!-- Spring Boot Starter for Redis -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!-- MyBatis Starter -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.3</version>
</dependency>
<!-- JWT -->
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.1</version>
</dependency>

2. 配置application.properties或application.yml文件：

# Redis
spring.redis.host=localhost
spring.redis.port=6379
 
# MyBatis
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.package.model
 
# JWT
jwt.secret=your_secret_key
jwt.expiration=3600000

3. 创建Redis配置类：

@Configuration
public class RedisConfig {
 
    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory connectionFactory) {
        final RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);
        return template;
    }
}

4. 创建JWT工具类：

@Component
public class JwtTokenUtil {
 
    private String secret;
    private long expiration;
 
    public JwtTokenUtil(@Value("${jwt.secret}") String secret,
                        @Value("${jwt.expiration}") long expiration) {
        this.secret = secret;
        this.expiration = expiration;
    }
 
    public String generateToken(UserDetails userDetails) {
        return Jwts.builder()
                .setSubject(userDetails.getUsername())
                .setExpiration(new Date(System.currentTimeMillis() + expiration))
                .signWith(SignatureAlgorithm.HS512, secret)
                .compact();
    }
 
    public boolean validateToken(String token, UserDetails userDetails) {
        String username = Jwts.parser()
