使用 Spring Security 自定义 Redis 密码验证的一个示例如下：

首先，你需要在你的项目中引入 Spring Security 和 Redis 相关的依赖。然后，你可以定义一个自定义的 `AuthenticationProvider` 来验证用户的密码。

下面是一个使用 Redis 连接池和模板类来验证密码的示例：

import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.security.authentication.AuthenticationProvider;
    import org.springframework.security.authentication.BadCredentialsException;
    import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
    import org.springframework.security.core.Authentication;
    import org.springframework.security.core.AuthenticationException;
    import org.springframework.security.core.GrantedAuthority;
    import org.springframework.security.core.userdetails.UserDetails;
    
    import java.util.Collection;
    
    public class RedisAuthenticationProvider implements AuthenticationProvider {
    
        private final JedisConnectionFactory connectionFactory;
        private final RedisTemplate<String, UserDetails> redisTemplate;
    
        public RedisAuthenticationProvider(JedisConnectionFactory connectionFactory,
                                          RedisTemplate<String, UserDetails> redisTemplate) {
            this.connectionFactory = connectionFactory;
            this.redisTemplate = redisTemplate;
        }
    
        @Override
        public Authentication authenticate(Authentication authentication) throws AuthenticationException {
            String username = authentication.getName();
            String password = (String) authentication.getCredentials();
    
            UserDetails user = redisTemplate.opsForValue().get(username);
            if (user == null) {
                throw new BadCredentialsException("用户名不存在");
            }
    
            if (!password.equals(user.getPassword())) {
                throw new BadCredentialsException("密码错误");
            }
    
            Collection<? extends GrantedAuthority> authorities = user.getAuthorities();
            return new UsernamePasswordAuthenticationToken(username, password, authorities);
        }
    
        @Override
        public boolean supports(Class<?> authentication) {
            return authentication.equals(UsernamePasswordAuthenticationToken.class);
        }
    }

然后，你可以在你的 Spring Security 配置类中将这个自定义的 `AuthenticationProvider` 添加到认证管理器中：
