RedisTemplate配置

在使用Spring Boot时，可以通过如下配置类来配置RedisTemplate：

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofMinutes(10))
                .disableCachingNullValues()
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));
        return RedisCacheManager.builder(redisConnectionFactory)
                .cacheDefaults(redisCacheConfiguration)
                .build();
    }

}

其中，`redisTemplate`方法用于创建一个`RedisTemplate`实例，同时配置了默认的key和value的序列化方式为`StringRedisSerializer`和`GenericJackson2JsonRedisSerializer`。

`cacheManager`方法用于创建一个`CacheManager`实例，并配置了默认的key和value的序列化方式为`StringRedisSerializer`和`GenericJackson2JsonRedisSerializer`，同时设置了缓存的过期时间为10分钟，并禁用了缓存空值。
