配置文件

spring:
  redis:
    host: localhost
    port: 6379
    password:
    timeout: 2000
    database: 0

    # 连接池配置
    jedis:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0

    # 或者使用 Lettuce 连接池
    lettuce:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0

Redis 配置类

@Configuration
@EnableCaching
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);

        // 设置序列化器
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer =
            new Jackson2JsonRedisSerializer<>(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,
            ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置key和value的序列化器
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setHashValueSerializer(jackson2JsonRedisSerializer);

        template.afterPropertiesSet();
        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheWriter redisCacheWriter = RedisCacheWriter
            .nonLockingRedisCacheWriter(redisConnectionFactory);

        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration
            .defaultCacheConfig()
            .serializeKeysWith(RedisSerializationContext.SerializationPair
                .fromSerializer(new StringRedisSerializer()))
            .serializeValuesWith(RedisSerializationContext.SerializationPair
                .fromSerializer(new Jackson2JsonRedisSerializer<>(Object.class)))
            .entryTtl(Duration.ofHours(1));
